I've been smoking for over 4 years, taking breaks on and off. I started early 9th grade, but only did it like once every other month, and then in 10th grade I started doing it almost daily. After 10th grade I did it about once every other week in 11th and then quit completely my senior year. I started up again my freshman year in college which is where I am now, but I started doing it daily. I usually smoke in my dorm room, at the frat house, or at my house. This issue has happened to me in my dorm room, and at my house. I only start having a bad trip when I notice that I don't feel like, for example when my toungue starts going numb. I usually react with paranoia and panick, for example the first time it happened my heart started pounding like crazy because I so afraid. The second time I was able to be a little more laid back, but I was still kind of afraid. I personally think that it's a side-effect from the weed, but it's hard because sometimes my tounge will not go numb from smoking weed. It's very strange, any help is greatly appreciated. Thanks idude.
