Amphetamines are central nervous system stimulants.  There are illegal forms of amphetamines and also those that are only available via prescription and thus are legal.  Amphetamine was initially given to individuals who suffered from hyperactivity, asthma and sleep disorders.  In the early part of the 20^th century synthetic forms of amphetamine (ephedrine) could be purchased over the counter and did not require a prescription.  This lasted for roughly 20 years and then they were pulled off of the shelves. In WW2, soldiers were given amphetamine in order to increase their energy levels and stave off fatigue.  It was also helpful in keeping them alert.

Individuals that take amphetamines will experience rapid heart rate and increased blood pressure. They may feel powerful, aggressive and focused. Many will lose their appetite. These are all short term affects of the drug.  Individuals that consume amphetamine chronically will also experience long-term effects, some which are very damaging. They include significant weight loss, the shakes, tremors, hallucinations, the inability to sleep, paranoia and psychosis.

Amphetamines can be addicting.  Individuals that take them may build up a tolerance that requires them to consume more of the drug in order to experience its effects. This can be quite problematic. Taking more and more of the drug puts users at an increased risk of overdosing.  One of the most well-known and dangerous amphetamines, is methamphetamine. Meth is extremely powerful and addicting. It also can cause the degeneration of the user at a rapid clip. Many meth addicts are nearly unrecognizable to your family and friends after taking the drug for only a short amount of time. Violence, domestic violence and aggressive behaviors are hallmarks of methamphetamine use and addiction.

Amphetamines are powerful central nervous system stimulants. Individuals that consume them will be energized both mentally and physically. There are legitimate uses for these drugs and also illegitimate ones. Amphetamine (Adderall) is prescribed to treat narcolepsy and ADHD. Examples of illegal amphetamines include methamphetamine and speed. Both of these are very dangerous drugs that can be addicting and in cases of overdose, lethal. Individuals who develop a dependency to an amphetamine may need to enter a drug rehabilitation facility. Those with an addiction to methamphetamine may especially require immediate and intensive treatment.
