The most common way of getting addicts into a drug rehab treatment center is by holding a drug intervention.

Those same studies conclude there are about eight million heroin abusers worldwide, with approximately a quarter of that group - two million - in the United States. On average, a heroin addict will spend anywhere from $100 - $200 to support their drug habit. The kerosene is removed and gas crystals of crude cocaine are left at the bottom of the tank. Typically, the crystals are dissolved in methyl alcohol. They are then recrystallized and dissolved in sulfuric acid, which results in cocaine that is about 60% pure. |
