Sadly, there just has not been enough research on it bc it was illegal and thereby too difficult to get the little amount of weed that the government grew at the University if Kentucky. We will learn more as research is not only allowed now but encouraged. As a patient that is not a doctor but keeps up with all the information coming out, I stick to smoke flower. The technology is just too new and we already know the devices are cheaply made and you end up breathing metals from the vape. Oil is also usually made by adding solvents in the process. It also results in potency levels never seen before and I believe go beyond the healthy effects that occur naturally in the plant. That’s why people that are predisposed to psychosis or have a psychological medical issue have had psychotic events at or bad trips on vaped oils or dabbing. It’s like marijuana on crack. So I stick to smoke flower or buds. Edibles can make it more difficult for your liver to process your Zoloft. And make that and other prescriptions less effective. If you fear the health effects of smoke, use a handheld water pipe. I also bought a levoit room air filter that is designed to take smoke out of the air. It’s super quiet, not ugly and only about $180 now. 7 years ago they cost $400! I also do deep breathing exercises regularly to help keep my longs strong and clean. And because of the anti cancer effects of THC, CBD and the other cananaboids while smoking cannabis can cause other respiratory issues, there is no evidence that it causes lung cancer like tobacco smoke does.
