Okay, so I've only been smoking for a couple years now. I used to do a little bit everyday until this year when I cut back to doing it about 2 days a week. Now sometimes when i take a big hit or blaze a lot I experience some weird **** happening to me. I start to feel really light headed and almost want to pass out. Everything goes black and I get dizzy. This has happened 3 times now and it's really weird. The first time my whole body was drenched in sweat and I can never hear anything when this happens. Its like a big ringing in my ears, or really loud static. DOES ANYONE KNOW WHAT THIS IS or how I can prevent it?
