How did your friend snort tar? You mean water lining? It's possible you missed the vein but with tar it burns like a motherfuck if you miss even a drip and usually will give a big histamine reaction. It's also very possible you have a higher tolerance, through use or just your body's natural state. Also maybe you got different potencies. Hard to tell
If its real heroin it won't get stuck in cotton or spoon, it's completely water soluble. Unless you didn't cook it and just left it in a big chunk.... Doubt you're that stupid though lol. Also possible you over-cooked it and burned it all away, but pretty unlikely.
Possible you got ripped off, got something fake, or super low purity. The first time I did tar I didn't get "high" whatsoever, just really hot And itchy. Sometimes you have to do it a few times to get your body used to it before its really euphoric etc
