Other Substances
Evidence-based overview of nicotine, cannabis, and other commonly used substances.
๐ The Story: Beyond Alcohol and Caffeineโ
Alcohol and caffeine get the most attention, but many people use other psychoactive substancesโnicotine, cannabis, prescription medications, supplements, and more. Each has distinct mechanisms, risks, and potential benefits. The goal here is not to be moralistic but to provide clear, evidence-based information for informed decision-making.
Here's what makes this topic important: many substances are marketed with health claims that aren't supported by evidence, while others have legitimate therapeutic uses that are stigmatized. Nicotine patches aren't cigarettes. Medical cannabis isn't recreational use. Prescription stimulants aren't the same as street drugs. Context, dose, route of administration, and individual factors all matter.
The principle: Understand mechanism of action, evidence for benefits and harms, and make informed choices based on your health goals.
๐ถ The Journeyโ
Whether quitting, reducing, or making informed decisions about substance use, the path involves understanding, honesty, and often discomfort before relief.
What to Expect (If Quitting/Reducing):
- Week 1: Awareness can be uncomfortable; denial may surface
- Weeks 2-4: Withdrawal symptoms (physical and psychological) peak then decline
- Months 2-3: Cravings still exist but become manageable; benefits start showing
- Months 3-6: New patterns established; occasional triggers but equipped to handle
- 6+ Months: Significant health improvements; former use pattern feels distant
๐ง The Science: Common Substancesโ
Nicotineโ
- How Nicotine Works
- Delivery Method Matters
- Benefits & Risks
Nicotine is a stimulant that binds to nicotinic acetylcholine receptors:
| Effect | Mechanism | Result |
|---|---|---|
| Dopamine release | Reward pathway activation | Pleasure, reinforcement, addiction |
| Acetylcholine increase | Cognitive enhancement | Focus, attention, memory |
| Norepinephrine release | Sympathetic activation | Alertness, energy, heart rate โ |
| Appetite suppression | Multiple pathways | Reduced food intake |
Why it's addictive:
- Rapid dopamine spike (especially smoking)
- Short half-life (~2 hours) โ frequent dosing
- Tolerance develops quickly
- Withdrawal is uncomfortable (irritability, cravings)
Nicotine harm depends almost entirely on delivery method:
| Method | Harm Level | Why |
|---|---|---|
| Cigarettes | Very High | Combustion produces tar, carcinogens, toxins; nicotine + smoke = deadly |
| Cigars / Pipes | High | Combustion products; often absorbed through mouth (oral cancer risk) |
| Vaping / E-cigarettes | Moderate-Low | No combustion; fewer toxins; long-term effects still uncertain |
| Smokeless tobacco (chew/snuff) | Moderate | Oral cancer risk; no lung damage; high nicotine absorption |
| Nicotine patches | Very Low | Controlled release; no combustion; minimal health risk |
| Nicotine gum / lozenges | Very Low | Minimal risk; slower absorption than smoking |
| Nicotine pouches (e.g., Zyn) | Low | No tobacco; oral absorption; less studied |
Key insight: Nicotine itself is not highly carcinogenicโthe harm from smoking comes primarily from combustion products, not nicotine. Pure nicotine (patches, gum) has relatively low health risk but remains addictive.
Potential benefits (nicotine alone, not smoking):
| Benefit | Evidence | Notes |
|---|---|---|
| Cognitive enhancement | Moderate | Improved attention, focus, reaction time |
| Neuroprotection | Limited | Some evidence for Parkinson's, Alzheimer's prevention (observational) |
| Appetite suppression | Strong | Effective but not healthy weight-loss strategy |
| Mood modulation | Moderate | Temporary improvement; rebound on withdrawal |
Risks (nicotine itself):
| Risk | Severity | Notes |
|---|---|---|
| Addiction | High | Highly addictive; withdrawal is uncomfortable |
| Cardiovascular stress | Moderate | โ heart rate, โ blood pressure (acute); less concerning without smoking |
| Insulin resistance | Moderate | May worsen glucose metabolism |
| Pregnancy risks | High | Fetal development concerns; avoid entirely during pregnancy |
Smoking-specific risks (not nicotine alone):
- Lung cancer, COPD, emphysema
- Cardiovascular disease (heart attack, stroke)
- Oral, throat, esophageal cancers
- Accelerated aging
- Smoking reduces life expectancy by ~10 years on average
The data is unambiguous:
- Smoking is the leading cause of preventable death globally
- ~480,000 deaths/year in the U.S. alone
- 10-year life expectancy reduction on average
- No safe level of cigarette smoking
If you smoke: The single best thing you can do for your health is quit. Use nicotine replacement therapy (patches, gum) if needed. Vaping is harm reduction if it helps you quit smoking, but not harmless.
If you don't smoke: Don't startโeven "social smoking" or "just when drinking" carries significant risk.
Cannabis (Marijuana / THC)โ
- THC: The Main Psychoactive
- Risks & Concerns
- Medical Use
- CBD (Cannabidiol)
ฮ9-tetrahydrocannabinol (THC) is the primary intoxicating compound:
| Effect | Mechanism |
|---|---|
| Euphoria / "High" | Dopamine modulation in reward pathways |
| Relaxation | GABA modulation; reduced anxiety (at low doses) |
| Altered perception | Sensory and temporal processing changes |
| Increased appetite | Hypothalamic signaling ("the munchies") |
| Impaired memory | Hippocampal CB1 receptor activation |
| Impaired coordination | Cerebellum and motor cortex effects |
Acute effects (during intoxication):
- Relaxation, euphoria, altered perception
- Impaired short-term memory
- Slowed reaction time
- Impaired driving ability (similar to alcohol)
- Increased appetite
- Anxiety or paranoia (especially high doses or sensitive individuals)
Short-term risks:
| Risk | Details |
|---|---|
| Impaired driving | Reaction time and judgment compromised; increases accident risk |
| Anxiety / paranoia | Especially with high-THC products or predisposition |
| Acute psychosis | Rare; more likely with very high doses or edibles |
| Cognitive impairment | Memory, attention, decision-making affected while intoxicated |
Long-term / chronic use risks:
| Risk | Evidence | Details |
|---|---|---|
| Dependence | Moderate | ~9% of users develop dependence; higher with early/heavy use |
| Cognitive effects | Mixed | Heavy adolescent use may impair development; adult effects debated |
| Mental health | Moderate | Association with psychosis, schizophrenia in vulnerable individuals |
| Respiratory (if smoked) | Moderate | Bronchitis, lung irritation (not lung cancer, surprisingly) |
| Motivation | Mixed | "Amotivational syndrome" debated; may affect some heavy users |
| Sleep architecture | Moderate | REM suppression (similar to alcohol); rebound on cessation |
Particularly concerning for:
- Adolescents (brain development)
- Individuals with or at risk for psychotic disorders
- Pregnant/breastfeeding women
- Those with cardiovascular disease (acute heart rate increase)
Legitimate medical applications:
| Condition | Evidence | Notes |
|---|---|---|
| Chronic pain | Moderate | Some benefit; not first-line treatment |
| Chemotherapy nausea | Strong | FDA-approved synthetic THC (dronabinol) |
| Appetite stimulation (wasting) | Moderate | AIDS, cancer cachexia |
| Epilepsy (CBD) | Strong | CBD (not THC) for specific seizure disorders |
| Multiple sclerosis spasticity | Moderate | Nabiximols (THC/CBD spray) approved in some countries |
| PTSD | Limited | Some evidence; needs more research |
| Insomnia | Weak | May help initiation but impairs sleep architecture |
Important: Medical cannabis should be under medical supervision, not self-prescribed. CBD (non-intoxicating) has better evidence for some conditions than THC.
CBD is non-intoxicating cannabinoid with different effects:
Claimed benefits:
- Anxiety reduction
- Anti-inflammatory effects
- Seizure reduction (proven for certain epilepsies)
- Pain management
- Sleep improvement
Evidence:
- Strong: Specific epilepsy syndromes (Dravet, Lennox-Gastaut); FDA-approved (Epidiolex)
- Moderate: Anxiety (some studies show benefit; needs more research)
- Weak/Mixed: Pain, inflammation, sleep (preliminary evidence)
Safety:
- Generally well-tolerated
- Minimal abuse potential (not intoxicating)
- Can interact with medications (affects liver enzymes)
- Quality and purity vary widely (unregulated market)
Bottom line: CBD shows promise for specific conditions but is overhyped in consumer market. Most products are unregulated and may not contain stated amounts.
๐ Signs & Signalsโ
How to Know If Substance Use Is Problematicโ
| Category | Healthy/Informed Use | Problematic Use |
|---|---|---|
| Frequency | Occasional, deliberate | Daily or increasing frequency |
| Motivation | Social, recreational, or medical | Coping with stress/emotions |
| Impact | No negative effects on life | Affecting work, relationships, health |
| Control | Can easily stop or reduce | Difficulty cutting back |
| Honesty | Comfortable discussing with doctor | Hiding or minimizing use |
| Consequences | None or minimal | Continuing despite negative effects |
| Thought patterns | Occasional consideration | Frequent thinking about substance |
| Tolerance | Stable dose | Needing more for same effect |
Specific Substance Signalsโ
Nicotine (Smoking/Vaping):
- Warning: Any daily smoking; can't go hours without craving
- Concern: Smoking first thing in morning; smoking alone
- Action needed: Tried quitting multiple times unsuccessfully
Cannabis:
- Warning: Daily use; using before noon; using alone habitually
- Concern: Memory/motivation issues; relationships affected
- Action needed: Can't stop despite wanting to; life goals suffering
Prescription Medications:
- Warning: Taking more than prescribed; running out early
- Concern: Doctor shopping; using without prescription
- Action needed: Can't function without it; withdrawal when stopping
Red Flags (Any Substance)โ
- Using to cope with negative emotions
- Hiding use from others
- Breaking rules or laws to obtain
- Relationships damaged because of use
- Tried and failed to quit or cut back
- Feel guilty or ashamed about use
- Physical or mental health declining
- Using alone more than socially
Positive Indicatorsโ
- Use is truly occasional (not habitual)
- No negative impacts on health, work, relationships
- Can easily take breaks or stop
- Comfortable being honest with healthcare provider
- Using for clear, legitimate reasons
- No escalation over time
Cannabis can be consumed multiple ways:
| Method | Onset | Duration | Lung Risk | Dosing Control |
|---|---|---|---|---|
| Smoking (joint, pipe) | Minutes | 2-4 hours | High (combustion) | Moderate |
| Vaporizing (dry herb) | Minutes | 2-4 hours | Lower (no combustion) | Moderate |
| Edibles | 1-2 hours | 6-8 hours | None | Poor (delayed, intense) |
| Tinctures / Oils | 15-45 min | 4-6 hours | None | Good |
| Vaping (concentrates) | Minutes | 2-4 hours | Uncertain (additives?) | Moderate-Good |
Edibles are particularly risky for overdose (non-lethal but very uncomfortable) due to delayed onset and long duration. People often consume more before effects are felt.
Prescription Medicationsโ
- ADHD Stimulants
- Benzodiazepines (Anxiety)
- Antidepressants (SSRIs)
- Sleep Medications
Amphetamines (Adderall) and methylphenidate (Ritalin, Concerta):
Legitimate medical use:
- ADHD: Well-established efficacy; improves focus, impulse control
- Narcolepsy: Promotes wakefulness
Mechanism:
- Increase dopamine and norepinephrine in prefrontal cortex
- Improves attention, focus, executive function
Risks with prescription use:
- Appetite suppression, weight loss
- Sleep disruption (if taken too late)
- Increased heart rate and blood pressure
- Tolerance and dependence (with chronic use)
- Potential for misuse
Non-prescribed use (cognitive enhancement in healthy individuals):
- Does improve focus and alertness short-term
- Not sustainable long-term (tolerance, side effects)
- Ethical and legal concerns
- Risk of dependence and adverse effects
Bottom line: Effective for ADHD under medical supervision. Misuse for "study drugs" is risky and not sustainable.
Diazepam (Valium), alprazolam (Xanax), lorazepam (Ativan):
Legitimate medical use:
- Acute anxiety or panic attacks
- Seizure emergencies
- Alcohol withdrawal
- Insomnia (short-term)
Mechanism:
- Enhance GABA (inhibitory neurotransmitter)
- Produces calming, sedative effect
Risks:
- Highly addictive with regular use
- Tolerance develops quickly
- Severe withdrawal (can be life-threatening)
- Cognitive impairment (memory, reaction time)
- Respiratory depression (especially with alcohol or opioids)
- Rebound anxiety when stopped
Important: Benzodiazepines are effective for acute use but problematic for chronic use. Long-term anxiety management should use other approaches (therapy, SSRIs, lifestyle). Tapering must be gradual under medical supervision.
Selective serotonin reuptake inhibitors (SSRIs): fluoxetine (Prozac), sertraline (Zoloft), escitalopram (Lexapro):
Legitimate medical use:
- Major depressive disorder
- Anxiety disorders (GAD, panic, social anxiety, OCD)
- PTSD
Mechanism:
- Increase serotonin availability in synapses
- Effects take 2-6 weeks to manifest
Evidence:
- Moderate-strong for moderate-severe depression
- Weaker for mild depression (lifestyle often as effective)
- Effective for anxiety disorders
Side effects:
- Sexual dysfunction (very common; 50-70% of users)
- Weight gain (in some individuals)
- Initial anxiety or agitation (first 1-2 weeks)
- Emotional blunting (some users report reduced emotional range)
- Withdrawal symptoms if stopped abruptly
Important: SSRIs are valuable tools for moderate-severe depression/anxiety but not without side effects. Work closely with prescriber; combine with therapy and lifestyle changes for best outcomes. Never stop abruptlyโtaper under supervision.
Prescription sleep aids (zolpidem/Ambien, eszopiclone/Lunesta):
Mechanism:
- GABA receptor modulation (similar to benzos but more sleep-specific)
Issues:
- Tolerance develops (diminishing effectiveness)
- Dependence risk
- Next-day cognitive impairment
- Bizarre sleep behaviors (sleepwalking, sleep-eating)
- Don't address root causes of insomnia
Better approaches for chronic insomnia:
- Cognitive behavioral therapy for insomnia (CBT-I)
- Sleep hygiene and circadian alignment
- Address underlying causes (stress, sleep apnea, etc.)
Verdict: Useful for short-term, acute insomnia (travel, crisis). Not a solution for chronic sleep issues.
๐ฏ Practical Applicationโ
Decision Frameworkโ
- Evaluating Substance Use
- Harm Reduction Principles
- Quitting / Reducing Use
Questions to ask yourself:
-
Why am I using this?
- Medical need? Recreation? Habit? Coping?
- Is there a healthier way to meet this need?
-
What's the risk-benefit ratio?
- What are the documented benefits?
- What are the documented harms?
- Does the benefit justify the risk for my situation?
-
Is this sustainable long-term?
- Will I develop tolerance?
- Are there dependencies or withdrawal issues?
- What are the long-term health effects?
-
Am I being honest with myself?
- Is use occasional or habitual?
- Am I minimizing risks or exaggerating benefits?
- Would I be comfortable discussing this with a doctor?
-
What do I need to know?
- Understand mechanism of action
- Know the evidence base
- Be aware of interactions with other substances or conditions
If you choose to use substances, reduce harm:
General principles:
- Know your source โ Purity and dose matter (especially illicit substances)
- Start low, go slow โ Test tolerance before full dose
- Avoid combinations โ Mixing substances increases risk (especially alcohol + anything)
- Don't use alone โ Have someone aware (especially first time or higher doses)
- Set and setting matter โ Environment and mindset affect experience and safety
- Plan for safe transport โ Never drive intoxicated
- Hydrate โ Especially with stimulants or in hot environments
- Know when to seek help โ Recognize overdose or adverse reaction signs
Specific harm reduction:
- Nicotine: Use patches/gum instead of smoking; if vaping, avoid black market products
- Cannabis: Vaporize instead of smoke; start with low-THC products; avoid driving
- Prescription meds: Use as prescribed; don't mix with alcohol; taper under supervision
- Alcohol: Limit quantity; hydrate; never drive; avoid before bed
If you want to quit or reduce:
Nicotine (smoking):
- Most effective: Combination of nicotine replacement (patch + gum/lozenge) + behavioral support
- Consider: Varenicline (Chantix) or bupropion (Wellbutrin) under medical supervision
- Support: Quitlines, apps, support groups
- Expect: Withdrawal for 1-4 weeks; cravings diminish over time
Cannabis:
- Gradual reduction works for most (not physically dangerous to quit)
- Expect: Sleep disruption, irritability, vivid dreams for 1-2 weeks
- Address: Underlying reasons for use (boredom, anxiety, sleep issues)
- Support: Therapy, support groups (MA - Marijuana Anonymous)
Prescription medications:
- NEVER quit cold turkey (especially benzos, opioidsโcan be dangerous)
- Work with prescriber to create taper schedule
- Gradual reduction over weeks to months depending on substance and duration
- Address underlying condition with alternative treatments
Alcohol:
- See Alcohol & Caffeine for detailed information
- Medical supervision important for heavy use (withdrawal can be dangerous)
General strategies:
- Identify triggers and develop alternatives
- Replace habit with healthier behavior (exercise, meditation, hobbies)
- Build support system (friends, family, groups, therapy)
- Address root causes (stress, mental health, sleep, pain)
- Track progress and celebrate milestones
- Expect setbacks as part of process, not failure
Special Populationsโ
- Pregnancy & Breastfeeding
- Adolescents
- Mental Health Conditions
Substances to avoid entirely during pregnancy/breastfeeding:
| Substance | Risk | Recommendation |
|---|---|---|
| Alcohol | Fetal alcohol syndrome, developmental issues | Zero tolerance |
| Nicotine (any form) | Developmental issues, low birth weight | Quit entirely; use support if needed |
| Cannabis/THC | Developmental concerns, low birth weight | Avoid completely |
| Most prescription meds | Varies by medication | Consult doctor; many require discontinuation or alternatives |
Even substances considered "safe" normally should be evaluated: Consult healthcare provider about all substances, supplements, and medications.
Substance use during adolescence (brain development period) carries additional risks:
Why adolescence is vulnerable:
- Brain still developing (until ~25 years)
- Prefrontal cortex (judgment, impulse control) matures last
- Reward system more sensitive
- Higher addiction risk
Particularly concerning:
- Nicotine: Rapid addiction; affects attention and learning
- Cannabis: Heavy use may impair cognitive development
- Alcohol: Binge drinking damages developing brain
- Stimulants: Misuse affects development and mental health
Recommendation: Delay substance use as long as possible. Brain development is a limited-time window.
Substance use with mental health conditions:
Depression/Anxiety:
- Alcohol: Worsens both (depressant)
- Cannabis: May worsen anxiety in some; temporary relief followed by rebound
- Stimulants (unprescribed): Can worsen anxiety; not treatment for depression
- Prescription meds: Important to follow medical guidance; don't self-medicate
Psychotic disorders or family history:
- Cannabis: Strong association with psychosis; avoid if vulnerable
- Stimulants: Can trigger or worsen psychosis
- Hallucinogens: High risk of adverse psychiatric events
Bipolar disorder:
- Cannabis, alcohol, stimulants: Can trigger manic or depressive episodes
- Medication adherence critical: Substances can interfere with mood stabilizers
General principle: Substances often worsen mental health conditions long-term, even if providing short-term relief. Work with mental health professionals for appropriate treatment.

- Stay honest with yourself about trajectory
๐ง Troubleshootingโ
Common Problems & Solutionsโ
| Problem | Why It Happens | What to Try |
|---|---|---|
| "I keep relapsing" | Addiction is powerful; triggers not addressed | Don't give upโmost people try multiple times; identify specific triggers; get professional help |
| "Withdrawal is unbearable" | Physical dependence; brain chemistry adapting | Medical support (especially for benzos, alcohol); symptoms are temporary; peaks then improves |
| "Nothing works without it" | Brain has adapted to substance | Temporaryโbrain will readjust; takes weeks to months; alternative strategies exist |
| "I only use when stressed" | Using as coping mechanism | This is problematic pattern; learn other stress management; address root causes |
| "Social situations are impossible without it" | Psychological dependence; social anxiety | Practice sober socializing; it gets easier; address underlying anxiety; support groups help |
| "I'm fine, everyone does this" | Minimization or denial | Compare to signs/signals above honestly; ask trusted person for honest feedback |
| "I can't afford to quit (time/energy)" | Fear of withdrawal or change | Continuing has higher cost long-term; plan for easier time (vacation, weekend); support makes it manageable |
| "My doctor prescribed it so it's fine" | Assumption prescription = no risk | Prescriptions can lead to dependence; have honest conversation with doctor; advocate for alternatives |
| "Just one won't hurt" | Underestimating addiction | For many substances/people, one leads to pattern returning; complete abstinence often easier than moderation |
| "I've tried everything" | Haven't found right approach yet | Combination approaches work best; professional treatment; medication-assisted; different this time |
Specific Scenariosโ
If nicotine cravings are intense:
- Use combination NRT (patch for baseline + gum for breakthrough cravings)
- Cravings last 3-5 minutesโride them out
- Keep hands busy (stress ball, pen, water bottle)
- Deep breathing exercises
- Remember they diminish significantly after 2-4 weeks
If you're smoking cannabis daily and want to stop:
- Expect 1-2 weeks of sleep disruption (will improve)
- Vivid dreams are normal (REM rebound)
- Boredom will be intense initiallyโplan activities
- Exercise helps with mood and sleep
- If using for anxiety/sleep, address those root causes
- Consider therapy for underlying issues
If concerned about prescription med dependence:
- Don't stop abruptly (especially benzosโcan be dangerous)
- Schedule appointment with prescriber
- Ask about tapering schedule (gradual reduction)
- Discuss alternatives for underlying condition
- If doctor dismisses concerns, seek second opinion
- Support groups exist for prescription drug dependence
If someone expresses concern about your use:
- Listen without defensiveness (defensiveness itself is a sign)
- Ask trusted person for honest assessment
- Consider that outside perspective may see what you don't
- Denial is powerfulโbe willing to examine honestly
- Getting help is strength, not weakness
โ Common Questions (click to expand)
Is vaping safer than smoking?โ
Yes, vaping is significantly less harmful than smoking cigarettesโthere's no combustion, so no tar or many of the carcinogens. However, vaping is not harmless:
- Long-term effects still uncertain (relatively new)
- Nicotine addiction still occurs
- Lung irritation and potential injury (especially black market products)
Best use: As smoking cessation tool, not as new habit for non-smokers.
Can I use cannabis safely?โ
Cannabis is not without risks, but many adults use it occasionally without major issues. To reduce harm:
- Avoid if adolescent, pregnant, or at risk for psychosis
- Vaporize instead of smoke
- Use low-moderate THC products (avoid ultra-high THC concentrates)
- Don't drive while intoxicated
- Avoid using as coping mechanism for mental health issues
- Be honest about frequency (daily use increases dependence risk)
Are prescription stimulants okay for studying if I don't have ADHD?โ
Short answer: No. While they may improve focus short-term, there are significant downsides:
- Tolerance develops (need increasing doses)
- Dependence risk
- Side effects (appetite suppression, sleep disruption, anxiety)
- Ethical and legal issues
- Not sustainable strategy for academic performance
Better approaches: Sleep, exercise, time management, removing distractions, breaks.
Is CBD actually helpful or just marketing hype?โ
CBD has legitimate, proven uses for specific epilepsy syndromes (FDA-approved). For other claimed benefits (anxiety, pain, sleep):
- Some preliminary evidence
- Needs more research
- Overhyped in consumer market
- Quality and purity highly variable (unregulated)
If trying CBD: Look for third-party tested products, start low, manage expectations, and don't rely on it as sole treatment for medical conditions.
โ๏ธ Where Research Disagrees (click to expand)
Cannabis and Cognitionโ
Whether chronic cannabis use causes lasting cognitive impairment in adults is debated. Some studies show deficits persist after cessation; others show recovery. Adolescent use appears more clearly harmful. The magnitude and permanence of adult cognitive effects are uncertain.
Nicotine for Cognitive Enhancementโ
Whether nicotine (in non-smoking forms) is a reasonable cognitive enhancer is debated. Some researchers point to benefits without major harm (if not smoked); others highlight addiction risk and cardiovascular concerns. More research needed on long-term use of pure nicotine.
CBD Efficacy for Anxietyโ
Whether CBD meaningfully reduces anxiety is actively researched. Some studies show benefit; others show placebo-level effects. Quality of studies varies. The hype exceeds the current evidence base.
Cannabis and Mental Health Causalityโ
Whether cannabis use causes mental health issues or people with mental health issues are more likely to use cannabis (reverse causation) is debated. Likely bidirectional, but the magnitude of causal effect is uncertain, especially for depression and anxiety (psychosis link is stronger).
