I have a professional vape (the arizer) which I set to 230. I always use the plastic tube (whip) at 230 degrees. The problem is that I notice that because it is not traditional smoke, I lose track of time, and I will hit the arizer, for about 3 or 4 hours. My head starts to feel fuzzy, and I am wondering if it is unhealthy to hit the vape for more than a hour or two. Is it dangerous to simply puff on it for a few hours casually? Or can it be harmfull to keep hitting the THC. It is hard to measure how well the vaporizer herb is hitting me, because everything feels cloudy. I fill the chamber with new bud only 2 or 3 times a day, and the chamber is the size of a small bowl/pipe, so not that much bud is being smoked!
