now ive read on the forums that tabs don't contain heroin, but why do the speed-based pills have more of a burn when i snort them, and the h-bombs (with brown specks, i might add) have a softer more powdery feel? it still burns, but it even smells like opiates when i snort them...ive never personally done heroin, but ive snorted norcos and roxicodones and had a similar scent/feel enter my nose...what could possibly be in my tabs that make me mellow and just want to stretch the fuck out when i snort a couple of "h-bombs" as i'm told they are?
