If you’re from Colorado, you’ve likely been party to this conversation, “You’re from Colorado; marijuana is legal there now, right?” For years Colorado was known for its beautiful mountains, but recently the questions seem to be centered around the legalization of marijuana. It’s long been known that smoking can lead to several oral health issues, not just bad breath and discolored teeth, but gum disease and oral cancer as well. As more and more states are legalizing marijuana for both medical and recreational purposes, you have to wonder what effect smoking marijuana has on teeth and what the research shows about marijuana and oral health.
