A person’s genetic makeup often determines how often their body metabolizes substances.


Our age plays a role in how our organs function as well as our rates of metabolism. Usually, someone who is younger will metabolize substances more quickly than someone who is older. Age is a huge factor in how quickly someone can eliminate toxins from their body.

Body Weight/Height

A person’s body weight and height determine how quickly they can eliminate a substance from their body.

Liver and Kidney Function

Someone with a dysfunctional kidney or liver will have a harder time eliminating the toxins from amphetamines from their body.

Frequency of Use

How much and how often someone uses amphetamines will greatly impact how quickly they can eliminate it from their body.


Although a person’s diet, supplements and how often they exercise play a role, generally someone with a higher metabolism will be able to eliminate toxins more quickly than someone with a slower metabolism.
