What illegal drug secretes a bad body odor?

Many legitimate and prescribed medications can cause bad or strange body odor. Among them, antidepressants such as Zoloft and Effexor are known for this. Medications that have dehydration as a side-effect or meds that in any way disrupt intestinal homeostasis may crete unpleasant body odor. Of course, someone who is abusing drugs may well be neglecting personal hygeine, as is the case with "meth mouth."
