Nearly 15% of all drug related emergency room visits come as a result of heroin use. According to police, the price of a dose of cocaine that would give a user a 20 minute high will buy enough meth to keep a user buzzed for a day or two. Three quarters of all heroin brought into the United States comes from South America and Mexico (with South America making up the majority of this amount) The resulting liquid contains unpurified cocaine alkaloids and may additionally contain waxy material from the leaves. This waxy material can be removed by heating and then cooling the mixture, a process that solidifies the unwanted wax. |
