Hello I'm a new poster on these forums but I had a question that I can't find anywhere. I'm aware that mixing cocaine and oxy's are not a good idea but from what I've found taking oxy's can help alleviate a comedown from cocaine. Is this still just as dangerous as mixing them at the same time even if I wait till my binge is over? It's 2 g of coke. Another side question, would mixing the two make either of these drugs stay in your system for longer than alone? Any advice would be greatly appreciated, thank you!
