Has anyone had any cannabis related health issues with concentrates? Would you mind sharing your experience & also what you've learned? Im starting to see more and more people have issues that i've previously had & am wondering what the hell might cause it? I'll go first. Somewhere around 2013 i stopped smoking flowers and strictly did BHO/Rosin for about 12-14 months daily. Eventually towards the end of the year my tolerance got ridiculously high, i started to notice something really strange which only could trigger while high on a good amount of concentrates. I would get these blackouts that last for a second, it always seems to start by "forgetting to breathe" followed by a big gasp of inhale & a jolt of electricity in my head which causes me to lose all motor function for that second but once i snap out of it, i feel completely normal which was super strange considering it literally doesn't last longer then a second. I've given two blood samples over a period of 3 months to check for multiple things yet they both came back pretty "normal". At this point, im 175lbs 5'9 and a pack of day smoker so i decided i needed to make some changes, the first and easiest thing was to convert back to flowers. When i did this it surprised the hell out of me because if i smoke flowers before or after concentrates i NEVER get that feeling of blacking out, so for some reason flowers seem to halt the blackout effects concentrates have on my body. Since then i quit smoking stoges, lost 25lbs, slowed down my concentrate intake and have NEVER had any concentrate related issues again. Has anyone had any related issues or possibly any research about this?
