From The Legal Perspective
The federal Drug Enforcement Agency (DEA) worked with officials in Thailand to shut down three online pharmacies that illegally sold substances containing controlled drugs such as phentermine, a diet pill. Though Internet shopping is legal, a prescription is needed to buy controlled drugs under the federal law. With authorities from both countries working together, Thai officials shut down three Internet pharmacies during November of 1999 through January of 2000.
However, the UN in February 2001 warned that not all countries had laws that could be used to stop Internet drug trafficking. The UN's International Narcotics Control Board called upon countries to adopt laws to halt Internet abuse such as the sale of illegal drugs by online pharmacies and drug stores without prescriptions.
