Id like to fill you in on the basics. I'm a 16 year old male. About 110 lbs. I've smoked roughly about 10 times. So I have a question. I smoked a couple days ago & I had what I would consider a bad experience. I only took 2 hits. That's what I usually take. This time things got crazy. Within the first minute I could feel it working. Usually it takes about 10 minutes. I also notice that I tend to get very worried & paranoid. I felt like I was dying. I have high blood pressure and a bad kidney & I felt like my heart was racing out of my chest & my kidney was failing. I was freaking out. I forced myself to sleep. I was so scared. Even after waking up the next day, I still felt high. I thought sleep got rid of it? Well my question is, what can I do to prevent this from happening again? I don't want to quit cause I do it only maybe twice a month, not often. Please, good answers.
