Black tar heroin is very potent and cost $50.00 per gram around here.
larry Reviewed by larry on . Opium anybody??? How much does opium go for a gram??? I have the choice between red rock and black tar. I have tried red rock and it was nice but wanted to try black tar. I got the red rock for $15 a gram and can now get the black tar for $15 a gram also. So are these good prices if you can get them??? -peace Rating: 5
