Other rugs, such as 3, 4-methylenediozydamphetamine and methylenedioxymethamphetamine (MDA  and MDMA), can be detected for up to two days in urine. Ephedrine and pseudoephedrine can remain present for up to five days.

As a rule, a drug is considered “gone” or no longer present in the body after 5 to 6 half-lives. This means it will take at least five to seven days for ONE dose of phentermine to completely leave the body. Of course, this half-life is influenced by all the other factors listed above to an unknown extent. When a person consumes amphetamines, they are broken down by the liver and released into the bloodstream. For instance, most employers who require testing will use a 4- or 5-panel drug test and an alcohol test. With that said, some professions involving personal and public safety may require regular 10-panel drug tests.



People who fall on the alkaline side of the scale tend to metabolize amphetamines slower than someone with a more acidic body chemistry.

Analyzing the results


Overall, the quicker the drug effect, the shorter the “high,” the faster the body can eliminate amphetamines from the system. Half-life cycles are multiples of the standard half-life time window. On average, up to 90 to 95 percent of amphetamines leave your system after four half-life cycles.


  • Darker hair typically has more methamphetamine in it than those who may have a lighter color hair.

  • In an inpatient medical detox setting, you are under round-the-clock care from doctors and nurses as your body is slowly weaned off the substance.

These may be more accurate in some cases, but the process is more complicated. Everyone has enzymes in their liver that metabolize, or break down, drugs like Adderall.
