Which sterioisomer of amphetamine is considered more toxic?
D-amphetamine, to the best of my knowledge DAT mediated uptake is linked to toxicity and it has a far greater affinity for that transporter than L-amphetamine. For reasons that only kind of make sense the NE system is durable as hell so NET uptake doesn't really cause any damage to the nerve terminals.
Granted I don't know how relevant if at all that would be in humans/anything outside a Petri dish.
