My dealer's coffee table ? Sorry but it sounds as if you are resembling yourself. But yes dope dealers mostly cut to make more money, but also add other products to give their product a kick, or taste to pass it off as "good shit". Fentanyl is just the latest. Arsenic has also been used as has been Quinine (bitter taste). There is so much milk sugar in Heroin that long time addicts actually have their teeth rot out, and get diabetes.
