I don't like the effects of marijuana very much, but that said, I have used it at certain times in my life and have made the decision to not use it. The opposition to prop 2 describes marijuana as highly addictive. That is a flat out lie! I used marijuana before I joined the Navy. They drug test before you go to bootcamp, they test when you get to bootcamp and they do random individual testing at every command as well as a few command-wide random tests per year. I can't really even say how many drug tests I had to do while I was in the Navy, but it was a lot. And every drug test is "observed" and the observer has to say and then sign a paper affirming that "I witnessed the sample leave the body and enter the bottle." Anyway, all that to say when I decided to join the Navy I went from daily use to no use. It was not hard. I had no withdrawals. The absolute hardest part of bootcamp for me was the first 3 days when I was suffering massive headaches from going cold turkey from my caffeine addiction, because you can't have caffeine until week 5 of bootcamp. The smokers were hating life as well, no tobacco in bootcamp. Meanwhile, stopping MJ wasn't even sort of a problem. MJ is NOT addictive. Any MJ user would have a harder time giving up their smartphone than they would have giving up MJ.
Can MJ be a habit? Yes, it can. Do some people get caught up in all sorts of habitual behaviours? Yes they do. Can it cause anxiety to break a habit? Yes. But MJ is not physically addictive. It just isn't. The biggest issue I think 99% of people who stop MJ after daily use is that they have a hard time falling asleep for 2-3 days because MJ is pretty good sleep medicine.
So my feeling is that I don't care if people enjoy the effects of THC or not. If MJ is beneficial to them in other ways, or even if the effects of THC that your everyday pothead uses it for is in some way beneficial to someone, I think we need to give people that option. Colorado, Washington, places that have legalized recreational MJ, they are doing fine. Will there be pluses and minuses? Yep, but I think the pluses are much greater, and decriminalization is the right way to treat MJ no matter what.
