Out of Joint?


Bill Clinton, 42nd United States President, famously, or infamously, confessed to having used marijuana, but claimed that he never had inhaled its smoke.  And Barack Obama, 44th President, all but boasted of having binge smoked marijuana in cars and in a Volkswagen bus with the windows shut tight, so that he and his friends could suck in every last whiff of the burning “weed.”  Only two presidencies and marijuana already had gone from verboten to akzeptabel.

But this is not a political blog.  It is all about you.  The scientific community still argues about the extent to which cannabis is a health hazard.  The people in the white coats will not answer the question definitively any time soon because of the powerful lobbies for and against marijuana.

Since most of what I see in the popular press is pro-pot, let me adopt the anti-pot position.  Most striking to me is the astounding fact that many “highly educated” people whom I know or whose work I read, while vociferously denouncing tobacco and its “profiteers” are most blasé, even supportive of, marijuana sucking.  It is as if they believe that we have two sets of smoke-receiving lungs—one for tobacco and one for what they casually call, “joint”.  But who am I to tell you about cannabis and tobacco? Rather, I should give you the information that I have seen recently, and you will reach you own decision. I’ll mostly confine myself to two respiratory-relevant sources.

The first source is Michael Greger, M.D. FACLM, a physician, who—among other professional activities— has published scientific papers in, Family and Community Health, Critical Reviews in Microbiology, the International Journal of Food Safety, Nutrition, and Public Health, and the American Journal of Preventive Medicine, and who has lectured to the National Institutes of Health, United States Congress, and Conference on World Affairs.  His opinion about cannabis smoking is:

“There is unequivocal evidence that habitual or regular marijuana smoking is not harmless and causes respiratory symptoms and airway inflammation.” If you take biopsies from the airways of those that smoke crack, cannabis, or tobacco, compared to nonsmokers, there is significantly more damage in the lungs of crack smokers, marijuana smokers, and tobacco smokers. And, the levels of damage seemed comparable—especially between the marijuana smokers and tobacco smokers—which is remarkable, since the tobacco smokers were smoking about a pack a day, whereas the marijuana smokers were only smoking about 20 joints a week, rather than 25 cigarettes a day. And those smoking crack were just doing a gram or two a week. So, to see similar rates of damage between marijuana smokers and cigarette smokers suggests each joint is way worse than each cigarette.” (2018)

The second source comes to us from the Alcohol and Drug Abuse Institute of the University of Washington (2018). 

“Based on the current scientific research, there is no definitively proven "safe" way of inhaling marijuana (smoke or vapor).

Inhaling marijuana smoke in the long-term is likely to result in damage to the respiratory tract.

Smoking both marijuana and tobacco increases the risk of damage from both substances.

While marijuana smoke contains carcinogens, research about the association between marijuana smoking and cancer is limited and conflicting. The same is true for other lung-related diseases.

Marijuana smoking does appear to increase cough, sputum production, airway inflammation, and wheeze.

Using a water pipe or bong does nothing to reduce exposure to tar and carcinogens in marijuana smoke; using a vaporizer may reduce the harm associated with smoking marijuana, however vaporizers may carry their own risks and more research is needed.”


Please recall that the aforementioned discussion is deliberately limited to a direct comparison of the respiratory effects of cannabis versus tobacco.  You, no doubt, have heard that marijuana also has been implicated in a host of other unhealthful conditions, such as accelerated heart rate, nausea, vomiting, and pregnancy risks.  Neurological and psychological problems also are common, such as: time distortion, mood change, in-coordination, confusion, memory deficits, irritability, sleeplessness, anorexia, cravings, and anxiety.

Therefore, if you plan to run for the United States Presidency or aspire to any other occupation, I suggest that you think at least twice about whether to smoke pot, with or without inhaling.
