Drug abuse = bad relationships with drugs. "Some people may prefer to see heroin addicts in a methadone treatment rather than seeking heroin on the street, but let us not kid ourselves: the 'treatment' is just addiction to another narcotic." [p2]
- All drugs are dangerous
- "wanting to change your consciousness is not a symptom of mental illness or an unhealthy need to escape from reality."
- "There are no good or bad drugs, only good or bad uses of drugs." [p180]
Is sugar a drug? Chocolate? - drug = any substances that in small amounts produces significant changes in the body, mind, or both. Difference between drug/poison is also unclear.
- What is "good" or "bad" is arbitrary between cultures
- "Most" view all nonmedical drugs other than alcohol, tobacco, and caffeine as bad
- North American Indians use peyote and tobacco, but consider alcohol a curse
- 1960s counterculture consider marijuana and psychedelics as good, but alcohol, tobacco, coffee, and other legal drugs as bad
- Yogis in India use marijuana, but teach that opiates and alcohol are harmful
- Muslims are ok with opiates, marijuana, khat, but not alcohol
- Early Muslim sects used coffee in rituals, but were against alcohol. Roman Catholic Church in 17th century used wine in rituals but were opposed to coffee
Stimulants
- Adrenal (latin) = epninephros (greek) = on the kidney
- Affect sympathetic nervous system, preparing body for fight/flight and suppress vital functions (e.g. hunger)
○ Caffeine: coffee, tea, kola nut, guarana, mate, cacao (also theobromine)
§ Bach was a coffee addict - wrote the "coffee cantata" in 1732 when coffee houses started to invade Europe. "Greatest of pleasures! Coffee, coffee, how I love its flavor, and if you would win my favor, yes! Yes! Let me have coffee, let me have my coffee strong"
○ Coca: simlar to caffeine but soothes the stomach and no jitteriness
§ 0.5% cocaine in coca leaves + many other alkaloids
§ Street cocaine is 60%. Similar to brewed beer or wine vs. distilled alcohol
§ Not very toxic - liver can detoxify every 30min
○ Amphetamines: structure similar to epinephrine / norepinephrine, but effects last 4hrs
§ Amphetamine (Benzedrine), Dextroamphetamine (Dexedrine), methamphetamine (Methedrine)
§ Reasons unknown why amphetamines have a calming effect in children
○ Tobacco/nicotine: one of most powerful / toxic, body quickly develops a tolerance very quickly (in hours)
§ Smoking destroys most of the nicotine
- Four exotic stimulant plants
○ Betel nut
○ Qat (khat, chat, miraa)
○ yohimbe
○ Ephedrine : similar chemical structure to epinephrine, but more anxiety / less euphoria
§ "Mormon tea"
- Advice on stimulants: keep limited, use purposefully, do not take to help perform ordinary functions (use as performance enhancing on special situations), take by mouth, take diluted forms, do not combine with depressants, avoid look-alikes/synthetics
Depressants
- Low doses cause people to feel stimulated, not fully understood why
- Sedative-Hypnotics:
○ Alcohol: From Macbeth: "it provokes and unprovokes, it provokes the desire but it takes away the performance"
○ Barbiturates / sleeping pills: barbituric acid, phenobarbital
○ Minor tranquilizers: benzodiazepines, less dangerous in combination with alcohol
§ Chlordiazepoxide (Librium), diazepam (Valium), alprazolam (Xanax)
○ GHB (gammahydroxybutyrate) - metabolite of GABA
§ does not cause tolerance or addiction, stimulates pituitary gland to release GH
○ General anesthesia: chloroform (highly toxic), diethyl ether, N2O
- Narcotics: from the greek word meaning "stupor"
○ Opiates. Opium (milky juice from papaver pods) - brought to the west as laudanum
§ morphine - from Morpheus, greek god of dreams - more powerful IV or IM
§ Codeine (methylmorphine) - weaker than morphine but more orally active
§ High potential for addiction / tolearance.
○ Synthetic opiates: heroin, methadone. Treatment = substitution of one dependence for another
Psychedelics / Hallucinogens
- originally called psychomimetics in Europe on the belief that they made people temporarily insane
- Psychedelics = mind manifesting. Lowest potential for abuse. In huge overdoses do not kill
- Indoles - rapid acting (20-40mins with peak at 102hrs)
○ LSD / lysergic acid diamide (LSD-25 because of its effect at 25microgram dose). Only physiological danger is contraction of the uterus - avoid if pregnant
○ Morning Glory seeds - ergine / lysergic acid amide. Other alkaloids cause nausea, need to be extracted
○ Mushrooms / psilocybin - loophole in growing since the spores do not contain psilocybin
§ Does not consider amanita to be a hallucinogen - it's a deliriant
○ Ibogaine
○ DMT / 5-MeO-DMT - smoking toad venom destroys most of compounds except 5-MeO-DMT
§ DMT is destroyed in the stomach (without an MAOi)
§ Rapid development of tolerance if smoked regularly
○ Yage - high level of trial/error to figure out combination of Yage with DMT
- Hallucinogens related to epinephrine / amphetamines (no indole) - gradual onset but longer lasting
○ Peyote / mescaline - 0.5g dose for 10-12hrs
○ STP (DOM) - synthetic mescaline
○ MDA (methylenedixoyamphetamine) - 100-150mg dose for 10-12hrs
§ Chemically related to amphetamine, although it causes relaxation (love feelings). Rarely have visuals
○ MDMA (methylenedioxymethaamphetamine) - shorter duration than MDA, 125mg dose
§ High day-after fatigue
○ Designer psychedelics: MMDA, TMA, PMA, 2CB, 2CT2
Marijuana
- In a class by itself, cannabinoids resemble no other molecule
- Highly hydrophobic - absorbed unevenly when eaten, and stay in the body long due to accumulation in fat
- Very low toxicity, low danger in mixing
○ Highly toxic if contaminated with paraquat (herbicide intentionally used to poison fields)
- Tolerance occurs - gateway drug theory is unproven
Solvents / Inhalants / Deliriants
- Organic solvents - 15-30min high, fear of popularity among children
○ aerosol propellants (Freon)
○ Amyl nitrate - historically used to relieve heart pain as an inhalant. Lasts only a few minutes
§ Called poppers because come in cloth-covered glass capsules that "pop" when broken
§ Popular as a sex enhancer, especially among homosexual population
§ Safe / high ADME
○ Butyl nitrate and isobutyl nitrite
- Deliriants: differ from hallucinogens because of marked confusion / disorientation
○ Can lead to toxic psychosis if overdosed in the brain
○ Nightshades (jimsonweed, datura, belladonna, henbane)
§ Family of plants includes tomatoes, peppers, eggplants, potatoes, and even tobacco
§ Contain scopolamine - poisonous in high doses. In low doses have been used in sleeping pills Even used in the past to make women amnesic to the pain of childbirth
§ Roots contain the least / are safest, seeds are the highest
§ Many physiological effects: fever, inability to focus eyes, rapid heart rate. 12-48hrs
§ Vivid hallucinations but also with some amnesia so hard to remember. More frightening / visions of monsters and devils than psychedelics
○ Amanita: traditionally used by tribes of Siberia. 30min onset, 4-8hr effect
§ Moderate doses - dreamy intoxication but physical discomfort due to toxicity.
§ Ibotenic acid and muscimol - similar to GABA
○ Nutmeg and mace (outer covering of the seed)
§ Contain myristicin, converted in the body to amphetamine-like psychedelics
§ Medium toxicity and heavy hangover. Unpleasant
- Dissociatives
○ PCP (phencyclidine) - originally marketed under Sernyl as an anesthetic. Many unpleasant side effects
§ Sold as "cannabinol" or synthetic THC (falsely)
§ 30min onset, 4-6hr duration, though oral doses last longer
§ Usually blank / rigid, but can result in agitation. Effects are not interesting nor productive
○ Ketamine - closely related to PCP, usually IV or IM
§ More useful dreamy state, without hyperactivity. Patients lie in peaceful dissociative states
Medical Drugs / Herbal Remedies
- Major tranquilizers: chloropromazine (Thorine), haloperidol (Haldol), fluophenazine (Prolixin)
○ for managing severe emotional disorders

○ DHEA (dehydroepiandrosterone) - weak androgenic effect, youthening effect
○ DMAE (dimethylaminoethanol) - small amounts in fish
○ Hydergine - derived from ergot, for TBI. Improves memory/learning
○ Selegiline (eldepryl, deprenyl) - treatment of parkinsons. Wakens brain functions
○ Vasopressin (diapid) - antidiuretic hormone, counteracts the crash of stimulants
