Why do I can't I control my bladder when I smoke Marijuana?

Well THC and other cannabinoids within Marijuana and its smoke, oil/butter, vapor byproducts cause a relaxation of the muscles all over the body and sense of euphoria-limiting your ability to control some of your bodily functions. The best advice I can give you is to use the restrooms before you smoke/vape/eat Marijuana in any form and to not drink as you smoke, as much as it helps with the coughing and dry mouth don't do it. If your mouth and throat get that dry just gargle and rinse your mouth with water and chew some gum. Once you go get your munchie foods you may drink as long as you compensate for how much you eat as the water or whatever fluids you drink will be absorbed by the food you eat. Hope that helps!
