I must have different body chemistry or something because I don't get anything near euphoria from IVing coke. I've tried all different purities. The most that happens is I get a rush of coke taste in nmy lungs followed by intense alertness and rapid heartbeat. If I do too much, my ears start ringing and I feel sick. There is certainly a rush of sorts, but to me it just feels uncomfortable and possibly scary. Never close to the euphoria I would get from dope.
