MARIJUANA AND PERIODONTAL DISEASE

A new study put out by JAMA Psychiatry indicates that use of marijuana is tied to periodontal disease.

The study was done in New Zealand over the past 20 years and involved over one thousand people. Their oral health was tracked from the age of 18 to 38.

The study concluded that those with a high incidence of marijuana use were more likely to have gingivitis by age 38 than those who were moderate in their use or did not use at all, by a factor of 3.

Earlier studies have found that heavy marijuana users also had a higher rate of alcoholism and spent only minimal time brushing and flossing their teeth.
