The various physical effects of methamphetamine include, increased energy, change in libido, increased sweating, decrease in appetite (anorexia), insomnia, dilated pupils, tightened jaw muscles (trismus), teeth grinding (bruxism), itching, nausea, vomiting, diarrhea, shortness of breath, involuntary body movements (twitches, grimacing, lip smacking, etc), increased heart rate, increased blood pressure, vasoconstriction, dry mouth, and a difficulty in urination. Serious physical effects include, possibly fatal lung and kidney disorders, possible brain damage, lowered resistance to illnesses, liver damage, heart attack, and stroke. Ecstasy-related emergency room incidents increased nationwide from 250 in 1994, to 637 in 1997, to 1,142 in 1998, to 2,850 in 1999. Both new and experienced users risk overdosing on heroin because it is impossible for them to know the purity of the heroin they are using. (Heroin sold on the street often is mixed with other substances such as sugar, starch, or quinine. An added risk results when heroin is mixed with poisons such as strychnine.) Heroin overdoses--which can result whether the drug is snorted, smoked, or injected--can cause slow and shallow breathing, convulsions, coma, and even death. Cocaine hydrochloride, the form in which cocaine is snorted or injected is often "cut," or mixed, with things that look like it. The final product can be from 1% to 95% pure. Common additives are sugars, such as mannitol, lactose, or glucose, or even sugar substitutes, and local anesthetics such as tetracaine, procaine, and lidocaine. Quinine, talc, and cornstarch have also been used. Some consumers may unknowingly purchase a supply without any cocaine, but just a cocaine substitute such as caffeine, amphetamine, PCP, procaine, and lidocaine. |
