I bought 3 grams at The Dispensary near Lumpini Park. I bought the weakest strain available (20 percent THC). I have to say everything has changed since I was a youth. Then you bought some cigarette papers, rolled up your joints, and used a roach clip at the end. Now you have 10 kinds of cigarette papers, filters, numerous strains, and you have to grind up the buds yourself.
After I figured out how to roll a joint (and I thought I was an old pro!) I smoked one thin joint and got so high I could hardly walk although my girlfriend said she didn't feel anything. I could hardly eat and had to lie down where I hallucinated until I feel asleep.
In short, this is not your dad's marijuana.
