What are the differences in the withdrawal effects of methamphetamines versus "mixed salt amphetamines"

Question

..better known as adderall. It seems to me that they may be very similiar, in cases where the adderall was actually illegally obtained and abused.

Answer 1

The difference is in dosage and strength. Adderall is administered in pills measured in 'milligrams'. Methampehtamine is substantially stronger, and generally dosed in hundreds of milligrams to grams at a time. They are essentially identical drugs, differing in potency, with the same withdrawal effects. The difference is that because Adderall is less potent (contains 'amphetamine' not 'methamphetamine') getting off it tends to be somewhat easier.
