What is known to happen if i were to mix librium with marijuana?

Sedation increases: Taking librium & marijuana will create more sedation (i.e. make the user more sleepy) and lethargy. Clearly a bad combination of drugs if you are looking to do anything that requires concentration and attention such as driving a car, taking an exam, making a landmark decision on the bench of the Supreme Court, or trying to do a lumbar puncture on a patient at 3am in an emergency room.

Not recommended: If Librium is mixed with Marijuana, it can boost the relaxant and euphoric properties of marijuana. The mixture is a potential overdose on Librium attributed to its use in combination with other CNS depressant. Ask your prescribing physician for more information.
