There is no strain for me, unless I learn how to enjoy feeling like I am dying with my heart racing a mile a minute and also suffocating. It used to chill me out but always came with bad side effects. Now I can't stand to be in a room where people are smoking, or even smell it at a concert just makes me sick personally because of how bad the addiction screwed up my life. I am sorry to say this because I used to love weed, but I am not sorry to say this because it was a sneaky little devil and completely fucked up my life which is a big deal to me since I don't like having my life ruined by an addiction to a silly plant.
For myself it has always been strangely actually much more addictive and destructive even than heroin somehow, although with that one I knew what I was getting into so I was able to consciously exercise self control from the start. With weed, I didn't have a damned clue what was in store for me, so I just chilled out and smoked as much as I wanted to, which turned out to be over an ounce a week of the best available herb in my realm, on top of a lot of hash oil dabs and imported hash. Somehow I never stopped to think, maybe that is a little too much since I was never using it medicinally (it doesn't help with my chronic pain). And then I realized that I could not quit without getting very, very sick and writing myself off for at least a couple months just to recover. One puff and it was back to square one. I had been quitting and relapsing for about 5 years once I finally managed to do it but I had to get a medical intervention which really sucked.
I don't smoke anymore - problem solved except that I get panic attacks now / live with extreme anxiety that I never had before, and it is obvious to me that this is a direct result of the cannabis abuse because I've never had anything remotely like that except after I quit. In fact it was the main reason that got me to quit, my reaction to the drug changed in a drastically negative way. Which makes me feel stupid, I wish I never touched the stuff and that's the only drug for which I will make that claim wholeheartedly. Nonetheless, I have my life back on track as a nice looking package of damaged but hopefully recovering goods. Another few years down the road, maybe my brain will heal up but it's tough to say. That darn weed captured my soul for a while though, and it scarred my brain with long term effects.
