Hmmm....nope. Meth heads and stimulant junkies end up fried......unable to function until they get back to baseline and it takes month+ for every month of recreational use to return to baseline......

add in actual chronic usage of amphetamines and cocaine and you end up with the attention span of a mouse and are less functional after you re-up than you were before you ever started....

the impact is so stark from amphetamines and stimulants it's fascinating that until you clean yourself up...you won't see it
