I smoked cannabis after I was prescribed to adderal... but I find that it makes me hungrier (amphetamine salts make me not want to eat)... I told my doctor this, and he told me that as long as I was on my medication, the benefits outweigh the risks (lung damage)... so I am quite happy to continue on, especially if medical marijuana becomes legalized in the state of Wisconsin. If it ever does, I may just ask to be taken off the adderall and switched to a strict regiment of nugget. I don't like taking the amphetamine salts... they mess with my sleep pattern, and they mess with my appetite, and they mess with my mood. Marijuana doesn't do anything but make me hungry and "comfortable" (not flying around on the web, searching everything and anything, while blowing off the originating task...).
