I've been smoking pot for about a year a half now. The first four times I did it with friends, very little happened. The fifth time however, probabaly beacuse of the strain, I got incredibly high. The only problem was it caused something in the area of a panic attack. I had absolute irational fear for about 2 hours. At the time, it was the worst feeling I'd ever had in my life. After that, smoking turned normal, had some great stones, doing it about twice a week. A month and a half ago, I hot knived for the first time which caused me to feel the same way I did that first time, only tenfold. I knew what it was and rode the fear out until it passed. It wasn't so bad. The only problem was, a week later, the same irrational fears started appearing in my daily routine, and since then I have been in a complete fog of semi-fear and outofbodiness. I was wondering if anyone had any similar experiences, especialy persisting ones, or if anyone could lend any advice. Thanks
