Can you smoke marijuana with sulfamethoxazole?

Wouldn't smoke sulfa: I would definitely not smoke the sulfamethoxazole! but seriously, there are no known drug interactions, so marijuana smoking would not interfere with the actions of sulfamethoxazole. There is some evidence that marijuana may sometimes suppress immune function but it is not clear if this is really the case. To be cautious, if you have an infection it would be wise to avoid or minimize marijuana use.

Pot/sulfa: Hypothetically, marijuana interferes with action of sulfa due to compromising the immune system.
