Smoking cannabis may cause oral cancer

A large general population study has shown that the degree of tooth loss at age 32 years is related to the level of cannabis use, irrespective of tobacco smoking.

According to  National Cannabis Prevention and Information Centre (NCPI),

There are a number of short-term and long-term health effects associated with cannabis use. One often less focused on, is the effects of regular cannabis use on oral health.

Regular cannabis users have poorer oral health than non-users, which is evidenced by higher rates of decay, missing and filled teeth, higher plaque scores and less healthy gums.

Saliva is the mouth’s own, effective cleaning system – it dilutes and washes away food particles and acids that cause erosion. Erosion occurs when enamel is dissolved from tooth surfaces, and teeth may appear shorter and have visibly worn surfaces, making them sensitive. Both cannabis and tobacco reduce saliva production leading to a dry mouth. If a person often has a dry mouth, erosion may damage their teeth more quickly.

Lung Damage Studies  The Hype: More Dangerous Than Tobacco  The Berkeley marijuana carcinogenic studies of the late 1970s concluded that “marijuana is one-and-a-half times more carcinogenic than tobacco.”
This is only true if you compare the smoke from the broad leaf of the tobacco to the broad leaf of the marijuana plant, which is how the government does it.,
The Facts: Not If You Smoke the Buds  The marijuana flowers have one third or less carcinogenic tars as tobacco leaf, and virtually all the carcinogens can be removed by using a water pipe system. Our government omitted this information and its significance to the results of such studies when speaking to the press.
In fact, it has been U.S. government policy to only compare leaf to leaf, even though it knows that 95% to 99% of marijuana smoked by Americans are the flowering tops (or buds) of the female plant.

Marijuana leaf sells for $20 to $100 per ounce on the street, but “buds” from the same plant will often sell for around $200 per ounce. Yet even the most naive marijuana smokers prefers a gram of bud to an ounce of leaf.
Yet this difference in tar comparisons with tobacco leaf carcinogens gives a totally false interpretation in the public mind of marijuana smoking verses tobacco smoking and the carcinogenic properties of each. Also a tobacco smoker will smoke 20 to 60 cigarettes a day, where a heavy marijuana smoker may smoke five to seven joints a day.
