Trying to determine exactly how long amphetamine is detectable in the body depends on many variables, including which kind drug test is being used. Amphetamine—also known as Biphematine, Delcobase, Desoxyn, Obetrol, Reds, Meth, Black Beauties, Crosses, Hearts—can be detected for a shorter time with some tests, but can be "visible" for up to three months in other tests. can be detected for a shorter time with some tests, but can be "visible" for up to three months in other tests.

Other factors that can come into play in tests being able to detect amphetamine is how frequent it has been taken, how much was taken, the amount taken, and the quality or potency of the drug.

Detecting amphetamine in the system is also dependent upon each individual's metabolism, body mass, age, hydration level, physical activity, health conditions, and other factors, making it almost impossible to determine an exact time amphetamine will show up on a drug test.

The following is an estimated range of times, or detection windows, during which amphetamine can be detected by various testing methods:

  • Amphetamine can be detected in a urine test from 2-5 days.
  • Blood tests for amphetamine can detect the drug for up to 12 hours.
  • A saliva test can reveal amphetamine for 1-5days
  • Amphetamine, like many other drugs, can be detected with a hair follicle drug test for up to 90 days.

Avoiding Overdose of Amphetamine

One reason that it is important to know how long amphetamine remains in your system is because of the risk of overdose. Here are some of the symptoms of a possible amphetamine overdose:

  • Restlessness
  • Confusion
  • Aggressive behavior
  • Feelings of panic
  • Hallucinations
  • Fast breathing
  • Uncontrollable shaking of a part of the body
  • Fever
  • Dark red or cola-colored urine
  • Muscle weakness or aching
  • Tiredness or weakness
  • Depression
  • Fast or irregular heartbeat
  • Fainting
  • Dizziness
  • Blurred vision
  • Upset stomach
  • Vomiting
  • Diarrhea
  • Seizures
  • Coma

Amphetamines Can Be Addictive

Another danger of taking more amphetamine than prescribed is that it can become addictive. When taken as prescribed for a health condition, amphetamines are not usually addictive, but when misuse—to get high or to improve performance—people can become dependent upon them.

The body can build up a tolerance for amphetamines, meaning it may require more of the drug to achieve the same effect. Taking more to reach the high or performance level you once experienced can lead to addiction.

You can tell if you have become dependent upon amphetamines if you experience withdrawal symptoms when you try to stop, such as:

  • Strong cravings
  • Mood swings
  • Lack of concentration
  • Visual or audio hallucinations
  • Headaches
  • Aches and pains
  • Increased appetite
  • Sleep disturbances

If you experience any of the above symptoms when you try to cut back or stop your use of amphetamines, you should seek medical advice immediately.
