The selling of illicit drugs, alcohol and pornography to minors are large sources of income for criminal elements in the societies of developed countries. Criminal operators seek to entrap youth in a state of dependence in their wares, and cross-connect their illicit service so that alcohol abuse and pornography may lead to drug addiction, prostitution and equally serious crimes.
After prolonged use of or the development of an obsession for a drug, the personality of the user is notably altered. The problem is exacerbated if the user has also become adjusted to criminal behaviour. While physical addition to a drug is not a prerequisite for criminal activity, the young person who tries to support a drug habit often commands limited funds and thus resorts to any of a wide range of illegal activities.
