Half-life durations can run from two to 12 hours depending on the type of amphetamine and route of ingestion used. 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. This means, 90 to 95 percent of amphetamine materials leave your system within eight to 48 hours provided youâre in good health.
By that time, the drug would no longer be working, though 25% would still be in your system. It takes another three days for half of that to be metabolized, and so on. The drug would likely be out of your system in about two weeks (based on metabolism rate toward the lower or fasted end of the scale). For slower metabolisms, this length of time would be doubled.
