I just got a prescription for benzphetamine and was wondering how(if possible) to turn them into meth?DOes anyone konw if its possible?

We get this question once every 4-6 months.

Yes it is possible, unfortunately it is too difficult for the novice chemist and even for an advanced chemist would not be worth the troble and expense as the extra potency of the final product doesn't make up for the loss of product in the synth.
