QUESTION

If you were on crystal meth and now take malaria pills, will the pills be canceled?

ANSWER

I am pretty sure there has never been any actual research on the effect of crystal meth (methamphetamine) on absorption of malaria medication. However, some compounds do interfere with the uptake of malaria medication, so it is possible that crystal meth could also have such an effect. Given the serious health consequences of using crystal meth, its effect on malaria medication is probably not as much of a concern as all of the other risks!
