I respect, and understand your views on the issue, I'm just not convinced yet. I'm not saying your points aren't valid, they are, but there are views that oppose legalization of marijuana that make sense as well.
Alcohol still kills tens of thousands of people each year. Nearly half of all auto accident fatalities are alcohol related. We have enough shit legalized as it is. I certainly do not want some high on pot, and drunk on alcohol, jackass operating any kind of heavy equipment around me or anyone in my family. That said, I do believe consequences for possession of marijuana are too stringent and mostly unhelpful. Marijuana may not kill anyone by itself, but if it compromises judgement then it has the potential to cause unwanted outcomes. Treating it like a prescribed drug, in pill form or something, actually makes sense to me, and is something I could possibly support.
