I actually have broken off contact with the drug scene, so I am not sure. The last time I have actually seen Heroin that was purchased from the streets ("Homeopathic Heroin", as I tend to call it) the person who bought it payed 30 or 40 euros (I think it was 30, but I'm not sure) was last August. He had a tolerance for opioids that was just a fraction higher as mine was at the time, but it was a complete rip-off. It had a trail that was as red as the Red Square when smoked on foil, one gram of that so-called "#3" was reported to be equivalent to about 100 milligrams of Oxycodone.
I'm glad that I walked away from the whole illegal drug scene, actually. Not only was the product aweful, most of the people were too!
I have heard about Antwerp having a higher quality of Heroin due to being closer to the harbour (although I probably used to have shit connections). Is it true that you can buy pure #3 that you can mix yourself (you get a bag of the "mix product" apart, or so I have been told)? Have you ever seen #4 or tar (or opium sold as tar) where you live?
I am very glad that I am finally out of that shit game, though. Never again, at least for me personally...
