Howdy, all first of all the purpose of this post I'm trying to determine if i need to take a extended break to give my receptors a break, so that i can finally getting vaked, with more of a noticeable high. First my bud quality: I usually have 20-30 strands, in quantity's ranging from a quarter to an ounce on hand all the time. I currently as I am a suppler for many peoples medicine, I can maintain large quantities at very little cost. In fact the cost of green for me is near zero. I also have a cousin who owns a dispensery in Colorado, who monthly sends me a medley of some great strands. In order for me to be even "somewhat high" I usually need to vape 2-3 sessions of .2 or more, I probably vape int total, 15-35 times on any given day that is like 200 + hits a day. But, since i need to take in so much vape, it really takes a toll on my respiratory system. Just all that forced sucking, and exhaling, and the expeletive effect of THC is really irritating my lungs, by the end of the day my chest tightens up and its like i have asthma until I fall asleep. I've started tallying the amount of bud I go through a day, and it goes from 5g's to almost 9 g's on some days. I've probably been on this level of use for about 2 years I usually wake up feeling completely fine, with symptoms returning by the end of the day especially if i vaped all day. I've been checekd by my doctor chest xray and mri, and my lungs are very clear, as I only vape no combustion. Also my highs just are good but mellow, and I assure you i'm starting at low temps, and moving up to high temps to get full spectrum of actives. I am also using high end vapes (Dcano, MFLB, ExtremeQ, DBV, SSV, LSV) with the best water diffusion available (Steamline, Waffel) So my question has anyone experienced this problem, how does my use compare to yours (especially for those of you who consider yourself a heavy user) Another thing to note, I really do vape from 8 am till 2 am, I work from home, run my own business, really no reason not to. Thoughts?
