In a recent episode of FBI: Most Wanted, Wellbutrin (under the generic name of bupoprion) figured as a drug of abuse. According to the show, it's often prescribed for PTSD, but the users take too much, then go on the street for additional supplies. It was described as "poor man's heroin."

Since I took Wellbutrin for several months (with limited efficacy), I found this entirely weird. I have no idea how accurate that was.
