Medicinenet has a real downer of a report, dude. Stoners are more likely to contract severe gum disease:
After controlling for other risk factors for gum disease, including tobacco use, the 32-year-old study participants who smoked the most marijuana were 60% more likely to show evidence of gum disease than 32-year-olds who had never smoked pot.
Almost one in three people had some evidence of gum loss.
