What do you mean you can't snort Morphine? You do realize Morphine comes in IR tablets, right? And excluding the filler they add in to make the pill itself, it's pure.
OK, you CAN snort morphine but you're body won't be able to metabolize it this way and it's a waste of the drug. The only effects you get from snorting morphine are the effects you get from the morphine filled mucus sliding down your throat and getting into your stomach so it can be taken in the system and reach the brain.
A shame that you folks across the pond don't get consistent access to nice mdma crystal. I've not come across pills at all since I started rolling this year, always been nice crystal/powder.
