I support legalization for most of the drugs. To elaborate: 1. All legal drugs will help with contaminated drugs and overdoses. 2. Legal heroin specifically also will help with contaminated drugs and overdoses. 3. Legal heroin is bad on different merits than help with overdosing, simply because it is so extreme and there is almost no way for humans to stop it's use.

Meaning that legal moderate drugs is almost pure benefit with zero drawbacks, while legal extreme drugs has both benefits and drawbacks simultaneously.
