I am on 20mg oral adderall, and I've had 3-4 beers, and smoked a little bit o' weed. Of course, the adderall is defeating the others by a long shot Man, the great thing about adderall is that it feels like shitty E... which is just speed lol. And since Dextroamphetamine is dopaminergic & serotinergic its a really crappy substitute... but still gets you high
