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.

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.
