Marijuana users have greater oral cavity deterioration than non-users, with increased risk of caries and periodontal disease. Higher levels of decayed, missing and filled teeth (DMFT) and bacterial plaque indices have been found in marijuana users than in non-users. Moreover, users are more prone to oral infections, possibly due to alterations in oral immunology, and drug use can be associated with dysplastic changes and potentially malignant disorders of the oral mucosa, increasing the incidence of squamous cell carcinoma. Marijuana cigarettes can contain up to twice the amount of polycyclic aromatic hydrocarbons as tobacco cigarettes, and the usual consumption without a filter leads to a higher concentration of inhaled smoke. However, the relationship between marijuana use and oral cancer is still not clear.
