If making drugs cheap means people get to keep a roof over there head & can afford to feed their family. Then I say we make drugs cheap.Look if someone is buying herb instead of properly feeding their kids/ making sure they have a roof over their heads; those embarrassments should not be parents.
When I was a teenager decent weed was $400 a zip. It was my anxiety medicine, I was dependent on it for that. There were times I was short on rent, or missed a few meals, or even had to sell something important. Financial issues snowball into relationship/friendship & professional issues quickly.
Affordability is KEY to reducing the harms of a dependence. Wether its insulin, weed or any other drug. The more expensive the drug, the more harm.
It never gets talked about but most "drug problems" are really just money problems.
