Is 72 hrs long enough for meth to get out of your urine? only a small amount and not a frequent user

Probably: 72 hours is the average time it takes for methamphetamine to drop off a urine drug test but many factors can affect this including the pH of your urine, level of hydration, activity, how much you took and by what route. If important issues like a job or court orders ride on this I would delay beyond 72 hours. 96 would be safer and one week or more, ideal
