Ask a Stoner: Why Does Cottonmouth Last So Long?
Dear Stoner: Why does smoking weed make my mouth so dry for the rest of the day? My girlfriend knows that Ive smoked hours after the high wears off, like she can taste it.

Think your fresh breath will survive an hour after smoking with no water? Forget it.
Dear Dry Mouf: Your girlfriend doesnt notice pot in your mouth hours after you smoke it, just its drying effects, according to well-known dentist and bacteriologist Dr. Harold Katz. Smoking reduces saliva flow to your mouth, he says, leaving more food debris there while also keeping bacteria that causes bad breath alive. If dry mouth is left untreated, it can take its toll on a persons oral health and cause many side effects, Katz notes. Consequences include oral fungal infections, mouth sores, cavities, gingivitis, receding gums, tooth abcesses and even a loss of teeth.
Cottonmouth is one of the most annoying side effects of smoking. Try to remember to carry water at all times something potheads rarely do or your girlfriend will continue to hate on that dry, barren wasteland when shes forced to kiss it. Youre probably not smoking enough to have a mouth that looks like a garbage disposal, as Katz describes it, but youd still be smart to stay diligent with your oral health. Your girlfriend will thank you.
