I have experienced panic attacks, like you can't believe. So has my wife. They are not caused by ganj, but can be brought about by smoking it. The panic attacks are always caused by something more serious (i.e. shite boss, inhuman deadlines, girlfriend/boyfriend drama, health concerns, money concerns, family bullshit, etc.). When I was really suffering from panic atttacks, my boss was selling me coke, and taking it out of my paycheck, working me like a slave (switching my shifts constantly), and a bunch of people dies in my family all at once. My solution was to find a new job, stop doing drugs, and spend some serious time trying to calm the fuck down. I can enjoy weed again, but for that moment in life, not smoking it made all the difference.
Panic attacks suck so bad. I wish you the best, and please don't do anything drastic. :)
