Methamphetamine

About Methamphetamine Stimulant Limited medical use: narcolepsy, weight control DEA: Schedule II drug
5
Methamphetamine Availability Historically existed as independent laboratories DEA: In 2001, 12,715 labs reported; in 2007, 5,910 labs Reduction due to 2005 U.S. restrictions on OTC cold medications, Mexico restrictions in 2007Mexico Production thought to be increasing as cooks find ways around the regulations (smurfing), some Mexico operations moving to U.S. ~$30-60/gram, depending on purity (“pure gram” price significantly higher)price Purity has been reduced, perhaps due to regulation
6
Methamphetamine Forms Snorted, smoked, orally ingested, injected
7
Methamphetamine Effects Intense high/euphoria May last up to 12 hours (longer than cocaine) Meth known for its dopamine-related effects (Meth Inside and Out clip)effects Increased blood pressure Increased sensation of energy, alertness Higher dopamine levels than cocaine Effects of those near a meth lab (KING TV, November 2009)meth lab
8
Methamphetamine Effects Chronic users may experience hallucinations, rage, paranoia, heart inflammation, sores from “crank bugs”; body wasting, “meth mouth;” brain cell death; damage to dopamine-, serotonin-containing nerve cells“crank bugs”; body wastingmeth mouthbrain cell death Dopamine damage may result in similar symptoms seen in Parkinson’s disease Damage may at least partially return to normal, when meth use halted

31
About LSD Discovered by Albert HoffmanAlbert 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.”
