"Cottonmouth" is a mental condition from smoking weed. At a low to mid level high cotton mouth will occur when the mind is being offset by T.H.C. Your mouth is actually wet and you are still salivating, it is just a mind game. At a high level of "highness"(blown), cottonmouth can occur and can lead to dehydration.

occurs after one smokes marijuana; refers to the mouth becoming exceedingly dry, spit becoming sparse and thick, and the roof of the mouth becoming seemingly impossible to reach with your tongue
After smoking the weed Diana found stashed in her dad's apartment, Mel, Grace, and Diana had a bad case of cottonmouth and were desperate to get to Sonic for Route 44 oz. slushes.
