What is the legal status of these chemicals?
While legal under federal law, products containing JWH-018 and JWH-073 are banned in several states and by the U. S. armed forces. At present, JWH-250 is illegal in only one state. Legal restrictions on these compunds are likely to be imposed nationwide. Additionally, they are banned by a number of European countries, including Britain, France, Germany, Poland and Russia, as well as South Korea. The Drug Enforcement Administration (DEA) labeled them a “drug and chemical of concern” in 2009.
