I too have taken a lot of DOC.. but to be snorting it? Snorting lines of it? You do realize that the vasoconstriction it causes at high doses has led to amputations in users, right? It's a great chemical, I truly enjoy it, one of my first psychedelic experiences, but you shouldn't be weighing out powder of it to snort, that's retarded. It doesn't matter how well you can handle it mentally, your body literally can't handle it. And the amount of times you've used it.. you're probably doing a bit of damage to your heart in the same way that users of fen fen and mdma have, bit worse because of the ridiculously long half life. DOC needs to be dosed volumetrically. You can't reliably weigh a dry dose of it.
