I'll join the conversation!
The very idea of criminalizing possession should have never been considered in a free country. I live in Canada, and part of the barriers to legalizing weed is that we signed 3 international agreements banning the sale and consumption.
How oppressive is it to dictate what I do with my own body? How disgusting is it that we throw addicts in jail instead of addressing addiction for what it is, a mental health problem? Why do we continue to criminalize drugs that aren't on the books yet? Three years ago the Canadian government criminalized Salvia. No real problem with it, it's not being widely abused, it's not addictive. But it was a drug they took notice of, and apparently grown adults can't make their own choices.
