· People believe snorting like percosettes and vicodin is a waste, just chew them. I disagree, I can swallow half a 10mg vicodin and feel really nothing. If I had snorted it, Id feel pretty good. I usually eat a 7.5, then snort half of another one, and snort the other half about 30 minutes later. and I feel pretty good for about 2-3 hours.
