hey, well i have extensive experience with IV coke use. To begin with nasal vs smoking vs IV they all feel different almost as if thry were diff drugs. well if u compare inhaling to IV Is like comparing someone running to a JET going full Speed or someone sky diving. I'm gonna try to explain as detailed how it feels to IV coke. First u prepare the shot AND shit bla bla. When u get that shit into ur bloodstream, after less than 10 seconds u go deaf, u can speak AND not hear urself. Then u stsrt tasting the coke in the back of ur mouth, almost as if u had swallowed a bag of coke. When u do too much there's something ppl call the Metallic train, it's what most IV coke users are aiming for. There's a very thin line with this effect AND an overdose. Anyway when u go deaf like i said if u do enough u hear this Metallic distorted sound like a swoosh ur heart feels like it's gonna beat out of ur chest, the paranoia sets in. It's pure bliss, orgásmic AND scary as fuck at the same time. I've had countless seizures from doing coke this way, burned out veins AND arritmia Now. So to sum it up it's not worth doing this shit, it's very hard on ur vascular system but well I'm nobody to Tell u or ur bf what to do ur grown UPS. Just Let me Tell u one last thing IV coke is the Pandora box, something that should never be open. I'm lucky to he alive AND I'm only 25. Well hope this helped u, cheers. nzn
