How often and why is marijuana mixed with crystal meth by users?
If by mixed you mean using crystal meth followed by marijuana, it varies of course from persons preferences to another but if you do a large amount of meth and become too edgy marijuana can take the edge off or help you come down. After effects being no differnt than normal after effects of meth, but again smoking meth can be a form of easing the come down from meth as well.
