muskrat is a specific composition of cannabis and is so - called because it has a very strong smell , but these days it has changed the generic term for stronger forms of the weed . it is listed as stronger because it contains much stronger levels of the active ingredient in cannabis , tetrahydrocannabinol ( thc ) . it also forms much lower levels of cannabidiol ( cbd ) , what is an counter - psychotic substance that can moderate the benefit of thc on the overall health of users .
The "skunk" cannabis is used to treat mental health problems.
