Ive never had a bad experience. I did have an interesting one though
a couple years back it had been around 6 months since I had used marijuana and 4-6 months before that it was a few hits off a bowl maybe 2-3 times a week.
I hit my friend up to purchase my first bag, and did so in the fred meyer parking lot from one of the cart boys, he was a clean cut asian dude, and gave me some really killer buds, said they were ak-47 (I actually have a pic for posterity! lol) I think it was that night, maybe the next when I went on the back porch of my apartment smoked a bowl listening to the Beatles, stood up, and fell over. I got to my knees (laughing pretty hard at myself) and opened the glass slider. I crawled my way to my bed where I called my old friend who I first smoked with and tried to tell him how high I was, but he couldnt understand me because I was laughing so hard. A couple of times I thought i might be dying, but i knew that one bowl wasn't going to kill me.
