Some adverse effects of marijuana may overlap with those of tobacco smoke. Not all studies confirmed whether marijuana per se is harmful to the airways (PMID 29629404). Variation in cannabis/marijuana/haschich potency, concentration (e.g. resin, hash oil), contamination with fungi (PMID 6348548) and possible adulteration should be considered (PMID:18494838). Reviews at PMID 24831571, 24897085, 25996274, 26935046, 29629404, 29971337. Some users vaporize cannabis using electronic cigarette devices (PMID 30835796)
