Widely used in the 1960s and early '70s for its intense effects, crystal virtually disappeared in the mid-'70s, but has resurfaced on a large scale in recent years. Other names: Crank, meth, go-fast, speed. Smokable forms of crystal are called "ice" or "glass." Appearance White crystalline powder. Although legal amphetamine is odourless, illegal forms of the drug often have a strong ammonia smell, due to incomplete clearing of solvents or reagents during manufacture. Trends Use of crystal soared in the 1990s as new sources of supply emerged, but it shows signs of levelling off in recent national surveys. Actions/Effects Crystal increases arousal in the central nervous system by pumping up levels of two neurotransmitters, norepinephrine and dopamine. At low doses, it boosts alertness and blocks hunger and fatigue. At higher doses, it causes exhilaration and euphoria. At very high doses, the drug can cause agitation, paranoia and bizarre behaviour. Physical effects include an increased heart rate and higher blood pressure and body temperature. Risks/Side-Effects Anxiety, emotional swings and paranoia are the most common psychological effects of chronic use. Symptoms increase with long-term use and can involve paranoid delusions and hallucinations. Violence and self-destructive behaviour are common. Overdose is also a risk with crystal. Symptoms include fever, convulsions and coma. Death can result from burst blood vessels in the brain (triggered by spikes in blood pressure) or heart failure. Demographics Whether crystal has topped out, tapped out or merely levelled off for the moment, whenever it's around it causes problems for people unaware of its reputation as a mind- and body-cruncher. In the United States, meth-related emergencies nearly tripled between 1991 and 2000, when the drug landed 29,702 users in U.S. hospital emergency rooms. - --- MAP posted-by: Beth
