Can you mix actimenophen with marijuana?
Yes, ofcourse you can mix them together. The more important question is: why would you do that? Acetaminophen has NO recreational value in it.
But yeah, there should not be any adverse reactions as long as you don't get enough Acetaminophen to overdose on (something above 4,000 mg for some people. Other people less; other people more).
You can mix marijuana with most every medication/drug, including Xanax. In fact, I do not know of any drugs that are dangerous to take with marijuana. Marijuana is neither a stimulant nor a depressant; it is a mild hallucinogen, and so it doesn't affect your heart or central nervous system the way other drugs (like speed, cocaine, heroin, oxycodone, Xanax, Ecstasy, etc. do).
