Doctor here!

Ive been waiting 14 years for this question, so heres 164k worth of knowledge.


THC reacts with Cannaboid receptors in the brain. A side effect of stimulating these receptors, is the parasympathetic nervous system delays.

The PNS controls saliva glands, and its delayed reactions cause your mouth to get dry, or "cotton mouth" because your saliva glands arent responding on time

Dry taste buds react more seriously to stimulation. Stoners are prone to drink sugary drinks like soda, because the brain rewards them for providing sweet, cold liquid.
