whoa! careful buddy! i dont know your tolerance level to opiates and benzos, but both will be amplified if combined, plus the combined result is going to be an overwhelming CNS depressing effect that can effectively stop your heart!
In NO way will i ever suggest someone tries this combo, but if you combine benzos and opes, PLEASE do very small amount! i mean like start with a .5mg xanax and 1mg oxy at the most. even then that could not be best idea. just the combination in general is extremely bad idea. even if the amounts are small enough to not cause any problems, the risk is too great. on top of that adding weed is just..... ridiculous to even consider opes and benzos together. I've almost lost a few friends who figured because of tolerance and not having enough benzo or opiates on its own to get much effect, they reasoned to themselves that it was necessary to combine to two. but still almost died!
combine either with weed might be nice, just please don't risk opiates and benzos together. Doesnt matter if you have high tolerance to both and not enough of either on their own to get satisfying effects. combining them is lethal.
