At home I lay down and sank into a not unpleasant intoxicated-like condition, characterized by an extremely stimulated imagination. In a dreamlike state, with eyes closed (I found the daylight to be unpleasantly glaring), I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colors. After some two hours this condition faded away.” LSD • • • Schedule I hallucinogen synthesized in 1930s Manufacturing secretive: Nick Sand (National Geographic) LSD famous/notorious for its short-term effects • Visual hallucinations (images, color, light) • Altered perception of senses • “Seeing sounds, hearing colors” • Color, size of objects • Altered perception of time, depth • Potential anxiety/panic • Experiences can vary widely • Serotonin receptors may be excited or inhibited • LSD experimentation on British soldiers (YouTube.com) LSD Chronic effects may involve flashbacks Sudden onset of abnormal perceptions Persistent flashbacks known as Hallucinogen Persisting Perception Disorder CONTROVERSIAL FIGURE Carl Hart, Columbia University (YouTube) 2C-I • • • • • “Smiles” Synthetic substance Usually inhaled or taken orally; may also be taken via blotter paper Stimulant & hallucinogenic properties Schedule I 2C-I • • • • Impacts dopamine & serotonin Onset of effects may not be immediate, triggering overdose Little information on brain impact Additives, chemical changes make drug unpredictable, similar to bath salts MDMA • Molly, Ecstasy, Thizz • Synthetic drug • Stimulant and hallucinogenic properties MDMA Acute effects on the brain Increased serotonin release Increased dopamine release Increased norepinephrine release Effects will vary since formula is not standardized or regulated Effects will vary based on the synthetic nature of substance MDMA-assisted therapy (Multidisciplinary Association for Psychedelic Studies, video; 0-2:00; 14 subjects, per website) MDMA Chronic effects are controversial, per Carl Hart Well-circulated animal studies showing neuron damage SYNTHETICS ARE CURRENTLY POPULAR 2C-I, MDMA, bath salts, synthetic cannabis Lower price (think about economy’s influence) Drug popularity changes with time (synthetics were popular in 1970s) Health-related issues will subsequently ebb and flow as drugs move in and out of favor That acknowledged, some can be devastating: Krokodil (CBS, 2013) CANNABIS Cannabis sativa Different subspecies/varietals used for clothing vs drug use Active ingredient: THC DEA: Schedule I Despite state regulations, marijuana still federally illegal CANNABIS (SOURCE: PROCON.ORG) Alaska (98) Montana (04) Arizona (10) Nevada (00) California (96) New Hampshire (13) Colorado (00) New Jersey (10) Connecticut (12) New Mexico (07) Delaware (11) Oregon (98) Hawaii (00) Rhode Island (06) Illinois (13) Vermont (04) Maine (99) Washington (98) Michigan (08) Washington, DC (10) CANNABIS THS acts on cannabinoid receptors, increases dopamine, serotonin Increases appetite ASAP Science: Your Brain on Marijuana (via YouTube) Chronic effects: respiratory distress, mood swings, memory & other cognitive factors may be affected (potential hippocampus damage) Overdose generally doesn’t occur Large amount required Smoking a lot may induce sleepiness Eating too much may trigger nausea, vomiting Q13 News story, Michigan Mixing any chemical substances can potentially cause a problem MUSHROOMS Psilocybin/psilocin are two active psychoactive substances found in “magic mushrooms” Couple dozen species Taken orally Recognized for centuries Probably used in religious rites Hallucinogen Schedule I MUSHROOMS Acute effects: Relaxation Altered perception of reality Altered perception of time Sense of connection to others/universe Visual hallucinations (images, color, light) Potential for anxiety and subsequent panic, heart rate & blood pressure increase Chronic effects: A “bad trip” may trigger fear Hallucinogens may exacerbate mental illness Being investigated as treatment for OCD, depression, smoking cessation Johns Hopkins Psilocybin Cancer Project (via YouTube, 0:30-4:03)
