The American Herbal Products Association (AHPA), Silver Spring, MD, has adopted a policy to support federal legislation to clarify that controlled substances, as defined by the Controlled Substances Act, may not be included as ingredients in dietary supplements. While no such legislation has been introduced in the U.S. Congress, AHPA plans to support this kind of direct approach to address occasional reports of products labeled as “dietary supplements” that contain anabolic steroids, a class of controlled substances that adulterate supplements and make them unlawful.
