¨Computer crime : Drug trafficking

Drug traffickers are increasingly taking advantage of the Internet to sell their illegal substances through encrypted e-mail and other Internet Technology. Some drug traffickers arrange deals at internet cafes, use courier Web sites to track illegal packages of pills, and swap recipes for amphetamines in restricted-access chat rooms.
The rise in Internet drug trades could also be attributed to the lack of face-to-face communication.
These virtual exchanges allow more intimidated individuals to more comfortably purchase illegal drugs.
The sketchy effects that are often associated with drug trades are severely minimized and the filtering process that comes with physical interaction fades away.
Furthermore, traditional drug recipes were carefully kept secrets. But with modern computer technology, this information is now being made available to anyone with computer access.
