Marijuana's Harmful Effects on the Mouth

Overview

Marijuana, also referred to as weed, pot and grass, is an illegal substance made from the Cannabis sativa plant. Tetrahydrocannibol (THC) is the main psychoactive ingredient in marijuana that provides a high or euphoric feeling. The amount of THC in the drug determines the level of the high, as well as its harmful effects. Physical and mental side effects are increased by more potent plants, which are determined by the type of plant, weather, soil and time of harvest.

Immediate Effects

Marijuana usually is smoked through a cigarette rolled with thin papers or through a pipe. The immediate effects include dry mouth and throat. Users typically experience increased thirst because of the dryness.

Immunity

Long-term marijuana use affects the immune system, which is vital to maintaining a healthy mouth and teeth. Doctors at Meriter Health Services report that continued use over a long period can lead to infections, tumors and cavities.

Teeth

THC interferes with the transfer of calcium through the body, a vital ingredient to healthy teeth. Long-term use of marijuana affects teeth and makes them more susceptible to rotting and decay.

Cancer

Marijuana's harmful effects on the mouth include the risk of mouth cancer. The Missouri Division of Alcohol and Drug Abuse reports that marijuana has been found to have a higher concentration of cancer-producing ingredients than cigarettes. Pot smokers typically hold the smoke in the lungs and mouth for longer periods than cigarettes, increasing the effects on the mucus lining in the mouth and exposure to the cancer-causing agents. The tar found in marijuana has developed tumors on the skin of animals in laboratory tests.

Self-care

A report by the American Medical Student Association says that marijuana users tend to get sick more than those who don't smoke pot. In addition to the lowered immune system and chemical poisons produced by the THC that linger in the mouth, marijuana users undergo personality changes that lead to poor hygiene and less attention to personal care. They lack energy and lose interest in everyday activities that once were important, including brushing their teeth, flossing and rinsing. The smoke from marijuana causes bad breath, and the lack of mouth care eventually produces additional problems for teeth and gums.
