just because it looks like black tar doesnt mean it is. No offence to you or your dealer or anything, i am sure you have extremely good hookups, but my guess is if it "fell into your lap" that it is probably fake. I have seen and smoked first hand fake opium that looks exactly like black tar. Its called sopium (i think) and it is sold in the back of high times. It even smells like opium but its fake. If the opium you obtained is any color but a shiny black its definately fake. If its a shiny black tar then take a VERY SMALL amount and smoke it. If you feel no effects, no, you dont need to smoke more, you have fake opium. People dont realize that opium contains morphine and is very very potent and can easily kill you if you do too much. If by some miracle you really do get real black tar opium(and again i do not mean any offence at you or your dealer, black tar is just a rarity and the best of people and the best of dealers have had fake shit). don't just back a typical "bowl" of it and smoke away, that amount of opium would kill you and the other 3-5 people smoking it. Be very careful, and the best way to think of it is if you dont know for sure you are high, you have fake opium
