The Effects
The Effects: http://www.kci.org/meth_info/sites/meth_facts2.htm
The physical effects of amphetamines are similar to those of other stimulant drugs. When amphetamines are taken by mouth, snorted or smoked, the user usually experiences feelings of euphoria, heightened alertness and greater energy. Heart, breathing and blood pressure rates increase, and sensations of hunger and fatigue are reduced. Heart palpitations may be experienced. The mouth is usually dry and swallowing is difficult, which makes eating food difficult. Urination is also difficult.
The users’ pupils are dilated, and reflexes are faster. Rapid speech often occurs, followed by slurred speech. Extremely high doses may cause people to flush or become pale, and cause a rapid or irregular heartbeat, loss of coordination and even physical collapse. Amphetamine injections create such an increase in blood pressure that strokes, high fevers or heart failure may result. As the drug wears off, feelings of fatigue or depression are experienced.
Amphetamines initially produce physical pleasure, so users easily are seduced into the repeated use of these drugs. Often users continually will take amphetamines to avoid the “down” mood they get when the drug wears off. Tissue tolerance develops quickly. It is not uncommon for some users to increase from 5 mg. to 1,000 mg. doses over a one-year period. “Speed freaks” are methamphetamine users who inject their drugs intravenously. Tissue tolerance develops very rapidly with them, as most methamphetamine users are compulsive/addictive users who cannot control their drug taking.
Long-term heavy use of amphetamines may lead to malnutrition, skin disorders, ulcers and diseases resulting from vitamin deficiencies. Regular use may contribute to lack of sleep and weight loss. Intravenous users are at risk for serious, life-threatening diseases such as AIDS, lung and heart disease and other cardiovascular diseases.
Frequent use of large amounts of amphetamines may eventually result in mental illness, suicide and violent death. Amphetamine-induced psychosis is a paranoid state that may develop after ingestion or the injection of large doses of amphetamines.
Amphetamine use increases self-confidence, which often ignores the reality of personal limitations. Amphetamine users may experience “Superman Syndrome,” in which they attempt to perform tasks they are incapable of performing. In well-rested persons, certain physical performances can improve with small doses of stimulant drugs. In tired users, stimulants cause most performance to deteriorate. Users often take unnecessary risks; truck drivers and motorists who use amphetamines are more likely to have accidents. Postponement of sleep due to amphetamine use may result in slower reaction times and decreased watchfulness.
This is a really interesting website to see before and after pictures of people who have used meth for different periods of time. http://www.drugfree.org/Portal/DrugIssue/MethResources/faces/index.html
