Ok I should probably mention that I've had some anxiety problems (mainly caused from weed but that didn't stop me). I've gotten my anxiety under control for the most part and haven't had a problem like this ina while btw. I just want anyones idea or opinion on what happened to me last night. I should also mention I've been smoking every day or twice a day for the past 6 months or so, so I have a big tolerance built up. Anyways, last night me and my friend blazed a good amount of grand daddy purple / northern lights from my bong and it was nearing the end up the night and I was watching tv as I was taking a bong rip and was not watching how much smoke was in there ad I breathed in and bam it hit me soo hard, harder than any bong rip has hit me before. a few seconds after the hit I felt really weird and out of it and nothing really made sense, soon after my legs and my chest started tensing up really tight and I was thinking that it was going to keep getting more tense, and it spread through my whole body and I couldn't really move, if I did I'd start shaking. I'm not sure if this was anxiety or the bud, or both. But I have to say it was extremely intense and I had to use all of my willpower to stop the tensing up and weird feeling in my body. I told my friend I had to relax and i closed my eyes for a good 2 hours until it passed and then I went upstairs and went to sleep. Has anyone ever experienced their body tensing up or shaking from coldness even though you're not cold? Every bong rip before that just made me a little higher, but that last one knocked me into a whole nother world...
I've had something somewhat similar to this happen to me. I was smoking a couple bowls then all of a sudden I started feeling terrible. My heart started racing and my muscles tightened. I felt like I couldn't breathe and eventually thought I was having a heart attack because I felt so badly. I called 911, got taken to the hospital and they ran tests on me, showing that I was OK. The next time I smoked, it happened again, which now, 6 months later, I attribute to anxiety about smoking and thats why I got fucked up. All I'm saying is you might want to take a break to help you. I took close to 6 months and just started again last weekend. Hope this is somehow helpful.
