
Famous/notorious for laboratory production, short-term dopamine
effects & long-term effects
Stimulant (blood pressure, heart rate, alertness)
DEA: Schedule II substance (Desoxyn: ADD, narcolepsy, weight
control)
Methamphetamine acute effects
Intense high/euphoria
◦ May last up to 12 hours (longer than cocaine)
◦ Meth Inside and Out video describing effects
 Energetic, talkative, excitable
 Insomnia
 Increased heart rate, blood pressure
 Sweating
 Dry mouth
 Jaw clenching
 Nausea, vomiting
 Comparison: meth vs cocaine,Brookhaven National Laboratory, 2008
Overdose
 DAWN: “stimulants including amphetamines and methamphetamine”
led to 93,562 emergency department visits in 2009

Methamphetamine chronic effects

Chronic users may experience hallucinations, rage, paranoia, heart “meth
mouth;” damage to dopamine-, serotonin-containing nerve cells
◦ Crank Bugs (Meth Project)
◦ Meth Mouth (Meth Project)
◦ Ashley’s Story (Meth Project)
◦ Research supports both brain damage as well as lack of brain damage

LSD

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.”
LSD
Schedule I hallucinogen synthesized in 1930s
• Manufacturing secretive: Nick Sand (National Geographic, 3:39)
• LSD acute 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)
Overdose
◦ Thought to be rare, but some individuals may not respond well, or may
experience problems if drug is different than LSD
◦ DAWN: 4,028 emergency department visits in 2009

LSD

Chronic effects may involve flashbacks
◦ Sudden onset of abnormal perceptions
◦ Hallucinogen Persisting Perception Disorder
 Visual images remain longer than in consciousness

Stimulant and

properties
MDMA
Acute effects:
◦ Euphoria
◦ Feelings of empathy/warmth toward others
◦ Jaw clenching
◦ Increased heart rate, blood pressure, perceived energy
◦ Common “rave” or similar environment can lead to excessive physical
activity, dehydration, increased body temperature
◦ Blurred vision/involuntary eye movement
◦ 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)
Overdose
◦ DAWN: 17,865 emergency department visits in 2008
MDMA

Chronic effects
◦ Depression
◦ Anxiety
◦ Sleep issues
◦ Effects controversial, per Carl Hart, Columbia University (YouTube)
◦ 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)
