The US Navy has banned sailors and Marines from using shampoo, lotions, and other body care products that contain hemp or cannabidiol. According to the official statement, their rationale is that the products could contain so much THC that it might "negatively impact mission readiness and disqualify a sailor from continued service." From Stars and Stripes:
The new rule follows a ban imposed last summer by the Navy on the ingestion of products containing hemp or hemp derivatives without a valid prescription, after a 2018 farm bill removed low-THC hemp from the Controlled Substances Act.[…]
The new rule still allows for the use of CBD-containing products that have been approved by the Food and Drug Administration, if a service member has a valid prescription. The rules do not prohibit the use of "durable hemp goods" such as rope, twine or clothing[…]
"We have to be fit to fight and can't take a risk in allowing our sailors to consume or use these types of products," said L.A. Parker, head of the drug detection and deterrence branch of the 21st Century Sailor office.
