COCAINE Metabolizes rapidly Effects last 1-2 hours Withdrawal can last 1-2 days METH Metabolizes slowly Effects last several hours Withdrawal can last several days COCAINE vs. METH [2]
2. EPIDEMIOLOGY
STATISTICS • In 2002: • 12 million US residents used methamphetamine at least once in their lifetime. • 600,000 US residents used methamphetamine in the past month. • 18,000 ER drug mentions (13,500 in 2000) • In 2003: • 6% of 12th graders had used methamphetamine in their lifetime.

3. THE CRYSTAL – HIV CONNECTION
THE BASIC PATHWAY 1. Crystal intoxication 2. Extreme sexual arousal 3. Decreased inhibitions/judgment Plus Increased sensation seeking 4. Unsafe sex/barebacking 5. HIV transmission
CRYSTAL & SILDENAFIL • The “crystal dick” problem • In 1998, Viagra became commercially available. • Since 1999, new diagnoses of HIV in men having sex with men have increased almost 18%.
CRYSTAL & THE INTERNET • Sex, both virtual and real, both safe and unsafe, is only a click away. • Lingo: • PNP = Party (drugs) and Play (sex) • Chem Friendly = Drugs • Barebacking = BB = Unprotected anal sex • In the Raw = Unprotected anal sex • Manhunt.com, Gay.com, Gaydar.com, Match.com, etc., etc., etc.
4. TREATMENT
NIDA RECOMMENDATIONS • Cognitive Behavioral Therapy (CBT) • The Matrix Model • Relapse Prevention • Methamphetamine recovery support groups • Motivational Interviewing • CSAT TIP #33, available from www.samhsa.gov
PSYCHOPHARMACOLOGY • No proven psychopharmacological interventions that reduce cravings associated with stimulants. • ? Vigabatrin • Gamma-Vinyl GABA [GVG] • 16/18 subjects tested negative for methamphetamine during the last six weeks of the trial. (Synapse. 2004;55:122-125)
CRYSTALPSYCHOTHERAPY • “There is pressure to show how life can be exciting in sobriety. Sobriety for the patient becomes a dreary foreign land, to which he feels exiled, sent away from the marvelous party by his own doing, and resenting the look of the new landscape. He wonders if the therapist’s life is one worth identifying with.”
5. THE PUBLIC HEALTH CAMPAIGN
HARM REDUCTION • Harm Reduction as Moderation Management • Harm Reduction as Reduction of Medical Consequences • The curse of the word “Abstinence”
