This combination is to satisfy the experienced addicts who have a tolerance to the heroin, not to new users. Experienced addicts actually ask for stronger strains such as this fentanyl/methadone combination. This can be a lethal dose when injected to newer inexperienced users, and even the experienced addicts if they are unaware. Unfortunately addicts all flock to locations where other people have overdosed. They do this to obtain the strongest kind of heroin, and they do not care about other people dying. All that addicts care about is getting themselves well, avoiding sickness, and getting high.
