Can you mix coffee and marijuana?

Absolutely! If you're caffeine and/or weed sensitive (in terms of anxiety or paranoia) then I wouldn't recommend it, but if you're neither, you can either mix the two separately, or, (even better), they make hash tea. "They" being the club I go to in Oakland, but maybe you could find the recipe online. Fun fact: Queen Elizabeth I used to drink hash tea for her menstrual cramps. :) Have a wonderful tea party!
