I am a former recreational smoker of marijuana. I have not smoked in years though. I was in my mid to late teens the last time I smoked. I used to get amazing feelings when I smoked..or so I thought. But there were times when I would get horribly anxiety attacks and feel like my heart was beating out of my chest. It was so scary but I still felt compelled to do it at times. How stupid!? I don't understand why. I think some of it could have been the peer pressure at the time. Have any of you dealt with anxiety when you've smoked? Also, what do you think causes the anxiety? Is it the strain of marijuana or just the way your brain reacts at that certain time?
