I think your viewpoint may be better served by the word "destigmatize"? In practice, the word "decriminalization" does not go as far as the word "legalization".

I think your viewpoint may be better served by the word "destigmatize"? In practice, the word "decriminalization" does not go as far as the word "legalization". Decriminalization only refers to removing criminal penalties, while allowing other ones to stand. Legalization refers to complete legalization (they'll most likely still regulate large-scale production like they do alcohol, tobacco, and other psychoactive substances). Ideally legalization should also come with expungement of convictions, as long as no other crimes were committed along the way (and even still, the charges directly related to the drugs themselves should still be vacated, even if there are other valid charges to hold).
