well first i'm obligated to note that marijuana smoking is illegal under u. s. federal law even in states that regulate the use of medical marijuana. but as to your question: there shouldn't be any conflict between cannabis use and vicodin (hydrocodone). cannabis is not an opioid the way hydrocodone is. both substances provide mild pain relief so if anything cannabis might make you feel as if the pain relieving effect of the hydrocodone is enhanced. that said it's generally not a good idea to mix drugs with similar properties (such as pain relievers). so your best bet is to avoid smoking marijuana while taking hydrocodone. the hydrocodone should provide sufficient pain relief on its own. if it doesn't please contact your health care provider for a different pain reliever. there are plenty to choose from! hope this helps!
is there a reaction between smoking cannibis and taking vicoden?
