Hi guys... So basically I was a daily smoker, smoked weed every day for more than a year, each day at least half a gram, I had some bad trips but it was rather rare (3 times a year tops) and not a big deal as after the bad trip I was just getting high just as I would get normally so... u know.. a bad trip sometimes happens... anyway, recently what started happening after I smoke, well I had my joint as regular, after I finished smoking it I was getting high all good, but in like 15-20 minutes after smoking, I started to get these really terrible, hard to describe feelings, something as if an electric shock occured in my body combined with pins and needles, starting from my abdomen reaching my head, this terrible feeling lasted about 10-15 seconds and went away, then came back after like 3-5 minutes, and this was going on for the duration of the entire trip, until I stopped tripping and I was feeling normal again. Now this happened to me for the first time in my life, as I mentioned, a feeling in the body as if u get pins and needles plus an ongoing light electric shock that you just can't get rid off... so as this happened just the first time I thought that it was just a bad trip, then I just had a pause for a day you know just to make sure, then smoked again, same thing happened... I was feeling desperate and I still am feeling desperate, not knowing what's going on, I thought maybe it's a shitty strain, so I got a different strain, same thing happened for the third time in a row, well, from that point on I knew I had to stop. So from a daily smoking I stopped just like that. It was nothing like setting issue or that I was with bad people around, nothing like that, got all the good lovely people around that I've known for years, I even managed to calm myself down throughout the trip in which I was suffering this terrible physical body feelings. I doubt it could be psychological as I have no worries and in general I am just a chill guy, and this happened several times in a row... well... I had a 2 weeks off weed, then, again, I had to try, I wanted to see if I maybe needed a break or something, so I smoke just a very little bit of the joint with my friends, not much, wanted to make sure that the trip is going to be as light as possible, and I was starting to get high, started to get the euphoric effects from weed, the shifted perception from the weed, just a regular mild high, and again, in just about 10-15 minutes, the terror started again... I was fully aware of it, I was trying to describe to my friends the feelings that I was experiencing, but it is just so strange, noone had idea what's going on, they suggested I should stop completely... and so I did... I do not smoke anymore as I am concerned that it might happen again... Its gonna be almost a month without weed and I just feel terrible, not because of some kind of withdraw effects or anything like that, but I just feel like life took away something from my life that I was truly enjoying... I have no idea what could be wrong in here... I smoked joints without adding tobacco to them, so pure weed only... I also do not drink alcohol as I just don't like it. I do not smoke cigarettes either... From a daily use a sudden surge of physical terror... any ideas guys what could be going on?
