Personally I've experienced and read about worse effects from marijuana on attention/memory/learning than from long-term stimulant use. Ironic since marijuana is often obsessed over by a certain loud group of drug users that consider it to be somehow special and consider users of other drugs to be somehow misguided.
Hahah very true! Though there is a body of evidence suggesting negative effects of even regular amphetamine on cortical function, I'd hesitate to extrapolate unequivocally even studies on primates to humans. Humans, at very least, respond to neurotoxicity differently, and at most, may be simply more resistant to neurotoxicity across the board. The fact that there isn't a readily observable phenotype for regular amphetamine induced long-term impairment in anything outside of the most extreme of addicts points to this, as well as the more empirical evidence of analyses of deceased meth addicts brains showing many DA markers not decreased that are substantially decreased in all other tested animals (the researchers actually concluded that meth neurotoxicity is absent in humans, but that seems unlikely).
