What is the effect of combining Valium and codeine?

could kill you.both are downers and can stop your heart as well as respiratoin. it happened to a freind of mine recently.take one without the other. best way.but if you can avoid t dont take either. im 17 and was a HEAVY user of lortab which is the same thing as vic. i quit for a while but the withdrawal is absolout helll.they are both so easy to get addicted to because every time you take it you will tell your self tht this is the last. i just had a relapse tonight after only five days. im not anti drug by any means but be careful with them.
