Alcohol, Tobacco, and Cannabis

Alcohol, tobacco, and cannabis use cause oral problems through direct contact, altered immune response, poor blood flow, carcinogenesis, teratogenesis, and accidental trauma. In the case of oral cancers, the effects may be additive when more than one substance is used.

Effects of Cannabis Use

  • Dental caries
  • Increased oral infections
