Cannabis - marijuana How does marijuana affect anxiety and depression? Does marijuana affect respiratory function? Especially during exercise? Is marijuana more destructive to your brain than alcohol?
5
Cannabis Cannabis sativa ◦ Different subspecies/varietals used for clothing vs drug use Active ingredient: THC THC is a cannabinoid ◦ Interacts with cannabinoid receptors in brain ◦ Many other cannabinoids exist, but not thought to cause psychoactive reactions DEA: Schedule I Despite state regulations, marijuana still federally illegal

Cannabis Acute effects THC acts on cannabinoid receptors, increases dopamine, serotonin Increases appetite ASAP Science: Your Brain on Marijuana (via YouTube)Your Brain on Marijuana Overdose generally doesn’t occur ◦ Large amount required ◦ Smoking a lot may induce sleepiness ◦ Eating too much may trigger nausea, vomiting ◦ Q13 News story, Michiganstory Mixing any chemical substances can potentially cause a problem
9
Alcohol vs Cannabis More research on alcohol Age dependent Amount of alcohol/amount of cannabis Mixing substances Alcohol interferes with neurogenesis of brain cells (Gary L. Wenk, Psychology Today, 2010) (Gary L. Wenk, Psychology Today, 2010) Cannabis: 2014 study showing regular use impacted decision-making and judgment (Published online before print November 10, 2014, doi: 10.1073/pnas.1415297111. PNAS November 10, 2014)
10
Depression and Anxiety Many use marijuana to ease mood Regular use may trigger, or worsen, either condition, especially in younger people 2013 Imperial College study showed lower dopamine levels in regular users, which may lead to more anxietyImperial College Marijuana, conversely, may help those with Post- Traumatic Stress Disorder ◦ Memory inhibition
11
Cannabis Chronic effects Respiratory distress Mood swings Impaired memory (potential hippocampus damage) Earlier researchresearch 2011 NIMH/NIDA study ◦ Daily use may reduce brain receptor number ◦ Receptors regenerated with cessation ◦ Society of Nuclear Medicine. "Chronic marijuana smoking affects brain chemistry, molecular imaging shows." ScienceDaily. ScienceDaily, 13 June 2011..
12
Marijuana & Respiratory Function During Exercise Acute effect: any smoke can interfere with oxygen binding to red blood cells Acute: marijuana can disrupt coordination, balance, reaction time Acute: increase heart rate and blood pressure Acute: stored THC in fat could be released into bloodstream during exercise Chronic: depends on how frequently one smokes, type of exercise

Dimethyltryptamine (DMT) Dimethyltryptamine (DMT) What is DMT? How does DMT work as a psychoactive drug?
14
Dimethyltryptamine Chemical structure Hallucinogenic ingredient Present in a variety of plants plants Occurs naturally in the body Schedule I substance Image source: Wikimedia Commons
15
Dimethyltryptamine Often consumed via beverage: ayahuasca tea ◦ Requires MAO-I (specific vine) ◦ Ceremonial purposes ◦ Ashland, OR Brazilian church lawsuit Can be injected, inhaled, smoked
16

17
LSD Learn the effects of acid Are there different types?
18
LSD Albert Hoffman: “Last Friday, April 16,1943, I was forced to interrupt my work in the laboratory in the middle of the afternoon and proceed home, being affected by a remarkable restlessness, combined with a slight dizziness. 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.”
19
LSD Schedule I hallucinogen synthesized in 1930s Manufacturing secretive: Nick Sand (National Geographic, 3:39) Manufacturing secretive: Nick Sand “Types” Same basic chemical structure Illegal, so cannot guarantee contents, care of product Light and air may degrade drug Dosage measured in micrograms (very small)
20
LSD Forms Crystal can be crushed, mixed with other materials into tablets: microdots Gelatin squares Converted to liquid paperpaper ◦ Dosed onto sugar cubes ◦ Placed on candy (gummy bears - Lake Tahoe, 2011, e.g.) Usually taken orally ◦ Can be inhaled, injected, applied transdermally
21
LSD Acute Effects Duration of “trip” = several hours in length 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 experimentation Overdose thought to be rare, but some individuals may not respond well, or may experience problems if drug is different than LSD
22
LSD Chronic effects may involve flashbacks ◦ Sudden onset of abnormal perceptions ◦ Hallucinogen Persisting Perception Disorder Visual images remain longer than in consciousness Dr. Henry Abraham (Tufts University) blogblog
23
LSD Research US Food and Drug Administration allowed LSD research Recent study sponsored by Multidisciplinary Association for Psychedelic Studies, carried out by Swiss physician Peter Gasserstudy ◦ Information published 2014 ◦ 12 patients with terminal illness, end-of-life anxiety ◦ Took two doses of LSD with talk therapy, across eight weeks ◦ Those with larger dose reported improvement
24
Which Drugs are Most Dangerous? Largely depends on availability ◦ Most emergency department (ED) visits: alcohol (DAWN, 2011)DAWN, 2011 ◦ Half + of 2.5 million ED visits: illicit substances
25

MDMA 3,4-methylenedioxy-N-methylamphetamine How does Ecstasy prove to help people with PTSD? What exactly is Molly & why does it kill people? How do you overdose Ecstasy? Molly?
27
MDMA Molly, Ecstasy, Thizz Synthetic drug Stimulant and hallucinogenic properties
28
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-assisted therapy ◦ More on MDMA therapy for PTSD (The Verge via YouTube, MAPS research through 7:00)YouTube
29
MDMA Chronic effects are controversial, per Carl Hart, Columbia University (YouTube)Carl Hart ◦ Well-circulated animal studies showing neuron damage
30
Emergency Department Visits
31
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)Krokodil
32
Which drugs are the most popular? (by country here) here
33
Mushrooms
34
mushrooms Psilocybin/psilocin are two active psyhoacticve substances found in “magic mushrooms” Couple dozen species Taken orally Recognized for centuries Probably used in religious rites Hallucinogen Schedule I
35
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) Johns Hopkins Psilocybin Cancer Project
