For those who don't know what it is from researching or smoking don't answer.
I think it's mainly numb, because I've had a load of spit in my mouth...yet it felt dry. How can it be dry, with spit? lol.
Also, when you are high, sometimes, you leave your mouth open for a while, and you don't even notice. So, that may be the cause of "cotton mouth".
My mouth gets super dry, like my spit straight turns to white foam when I have cotton mouth.
I get the same as Mackenzie, my moath gets dry and my spit gets all sticky.
just really dry and i have to spit a lot
