i would be able to tell you if something were say an og kush, or a haze, or say sour d, chemdawg, or something i've grown and am familiar with..
but if it's not something i've grown or one of the above that imo are pretty easy to tell apart, i think i'd be hard pressed to know what it was..
last summer me and a friend were drinking outside of the social distortion concert, and my friend will talk to anyone who stands still long enough.. long story short, he starts talking to these guys who were out there selling t shirts, and of course bud comes up.. one guy runs over to his audi r8 and grabs a satchel and opens it up, i smell the one bud, and said it smells like chemdawg.. it was a chem x, and he was pretty impressed...
