What are Amphetamines? 

Amphetamines are stimulants that speed up the body’s system. Many are legally prescribed and used to treat attention-deficit hyperactivity disorder (ADHD). Amphetamine was first marketed in the 1930s as Benzedrine® in an over-the-counter inhaler to treat nasal congestion. By 1937 amphetamine was available by prescription in tablet form and was used in the treatment of the sleeping disorder, narcolepsy, and ADHD. Over the years, the use and abuse of clandestinely produced amphetamines have spread. Today, clandestine laboratory production of amphetamines has mushroomed, and the abuse of the drug has increased. 

How is it Used?

Amphetamines are generally taken orally or injected. However, the addition of “ice,” the slang name of crystallized methamphetamine hydrochloride, has promoted smoking as another mode of administration. Just as “crack” is smokable cocaine, “ice” is smokable methamphetamine.

What Does it Look Like?

Amphetamines can look like pills or powder. Common prescription amphetamines include methylphenidate (Ritalin® or Ritalin SR®), amphetamine and dextroamphetamine (Adderall®), and dextroamphetamine (Dexedrine®).

Common Symptoms

Physical effects of amphetamine use include increased blood pressure and pulse rates, insomnia, loss of appetite, and physical exhaustion.

Overdose effects include agitation, increased body temperature, hallucinations, convulsions, and possible death.

What Are the Effects?

The effects of amphetamines and methamphetamine are similar to cocaine, but their onset is slower, and their duration is longer. In contrast to cocaine, which is quickly removed from the brain and is almost completely metabolized, methamphetamine remains in the central nervous system longer, and a larger percentage of the drug remains unchanged in the body, producing prolonged stimulant effects. Chronic abuse produces a psychosis that resembles schizophrenia and is characterized by: Paranoia, picking at the skin, preoccupation with one’s own thoughts, and auditory and visual hallucinations. Violent and erratic behavior is frequently seen among chronic abusers of amphetamines and methamphetamine. Drugs that cause similar effects include: dexmethylphenidate, phentermine, benzphetamine, phendimetrazine, cocaine, crack, methamphetamine, and khat.

Detecting Amphetamines

Amphetamines can be detected in the blood stream up to 4 days after the consumption of the drug. The amount of time available to detect amphetamines vary depending on the type of test you take. At Teststock, we carry many tests capable of detecting the presence of amphetamines. Our products include urine cup drug tests, urine dip tests, and saliva tests.

Legal Status

Amphetamines are Schedule II stimulants, which means that they have a high potential for abuse and limited medical uses. Pharmaceutical products are available only through a prescription that cannot be refilled.
