I pesonally don't think that smoking marijuana gives gum deseases and highers your chance of tooth decay. First of all there is not enough proof to say this because many cannabis smokers also smoke cigerettes which is proven to decay teeth. Also the American Medical Association, knows that Marijuana legalization is a big contraversal issue in the United States. Personally I think that Marijuana is more natural than putting man made chemicals in your body for the main symtoms like anxiety and pain that more than 50% of the medicated users use this drug for. While the doctors perscribe addicting opiods and benzos to the patients who should be able to be perscribe marijuana instead(which also is not phyically addictive.)
