Except in the case of opioids, government and regular ARE the problem. If they were legal and available through a regulated supply, most of the OD's would never happen. They happen because someone gets a dose of the drug that's 10-100 times stronger than the one they had yesterday.

That's no different than people going blind/dying from wood alcohol during prohibition.

The solution is to legalize and regulate, but I'm not holding my breath.

Yeah, seriously. Not everything can or should be addressed by for-profit businesses, or start-ups in particular.
