If the behavioral profile is the same, then the different effects on neurotransmitters balance each other enough to produce the same addictive or physiological response. The behavioral profile includes addiction. Illegal methamphetamine made from ephedrine is pure D-MAMP while Adderall is a mixture of D-AMP and L-AMP, that is the major difference between the two.
>The results of these studies indicate that, while the dopamine, norepinephrine and 5-HT responses to these drugs probably contribute to the expression of stimulant-induced behaviors, simple relationships between the neurotransmitter responses and the behavioral profiles were not evident.

@telos You are the only person here who has mentioned addiction even one time. I said "the effects of amphetamine use" aka, brain damage, heart problems, rotting teeth, withdrawals when you stop using it. etc....... And in response to your twisted logic on addiction and dopamine. Coffee gives less dopamine than cocaine but people are addicted to both. Some people have drank coffee and tried cocaine and never became repeat users, or addicts of either.
