The U.S. Air Force prohibits its airmen from use of supplements that contain hemp byproducts, such as hemp seed and hemp seed oil. The use of steroids is also prohibited, unless prescribed by a licensed doctor. Products used by bodybuilders as dietary supplements are generally not off-limits to airmen, although there are exceptions.
The U.S. Air Force aeromedical policy requires airmen on special duty, such as those on flying status or in the Personal Reliability Program, to report the use of artificial products marketed as dietary supplements.
While the use of hemp byproducts is not illegal in the United States, and the substances do not contain tetrahydrocannabinol, a prohibited marijuana ingredient, the seeds may become contaminated with the chemical during processing. If consumed by a member of the air force, THC can be detected during drug testing. Since it’s difficult to tell whether traces of THC detected in urine came from use of marijuana or hemp seed oil products, the prohibition against use of both substances by members of the Air Force stands.
Punishment for use of outlawed dietary supplements by Air Force personnel includes termination of service, criminal prosecution or administrative action. The airmen can avail themselves of nutritional products that do not contain prohibited substances at fitness centers within their bases.
