Does Marijuana Cause Lung Cancer?

there are at least 33 carcinogens in marijuana smoke such as polycyclic aromatic hydrocarbons which are products of combustion found in grilled meat and flowing through the bodies of those who smoke marijuana similar to what one sees going through the bodies of cigarette smokers that’s really remarkable most tobacco users inhale way more smoke into their lungs over the course of a day so on a puff by puffs basis is marijuana smoke really that much worse well it does seem to contain more benzopyrene and bends anthros een which are polycyclic aromatic hydrocarbon carcinogens compared to unfiltered cigarette smoke but it may just be that’s cannabis users inhale more deeply and then hold the smoke and longer which can end up depositing four times more tar in the lungs amplifying exposure to these carcinogens and unfortunately bubbling the smoke through water like in a bong does not appear to reduce the risks of tar build-up yeah marijuana smoke tar may have similar tumor promoting effects as cigarette smoke in mice but what about in men and women longtime marijuana users do have more cancer more lung cancer more oral cancer Voicebox cancer but only it seems because they also tend to be more likely to also smoke tobacco after cigarettes are taken out of the equation no increased risk was found same with head and neck cancer a one study found increased risk but five studies reported no association one study found decreased risk so yeah regular use causes airway injury that can lead to chronic bronchitis but no evidence of long-term lung damage like emphysema and despite the presence of carcinogenic components no apparent increased risk of lung cancer though evidence is mixed regarding the risk of heavy long term use and that may be the crux in terms of smoke exposure even smoking a joint every day for ten years may only translate to six months of pakad a cigarette smoking in most studies on tobacco smoking and lung cancer six months in a lifetime might get you classified as a never smoker it may take a couple years of cigarette smoking significantly bump lung cancer risk and so that would be like smoking a joint every day of your adult life no wonder we can’t find a lung cancer linked with casual marijuana use though there is an alternative explanation maybe the anti-tumor effects of the cannabis plant is counteracting the tumor promoting effects of the carcinogens in the smoke weight anti-tumor effects yes in fact the original demonstration of an anti-cancer effect dating back to 1975 was against lung cancer cells showing the THC can’t suppress their growth in a petri dish this kind of data has led to wild claims of cancer cures on the internet extrapolating the results of this preclinical work meaning like in petri dishes and test tubes to humans without any basis in fact as cannabis coiner this 2016 review has not been studied clinically as a treatment for malignancy in people but that’s not really true there was a pilot study performed on terminal brain cancer patients will find out what they found next you
