Have you tried meth? And very much doubt it, you may as well be taking adhd medication which having done many different types as perscription as well as recreationally, and done meth a few times smoked, insufflated abd orally, only difference was duration of the drug. I really dont think these amphetamibes are all that harmful or addictive to begin with a totally safe and non addictive stimulant like that sounds like absolute horseshit
