Story highlights

  • The FDA sent warning letters to four US companies regarding more than 25 products
  • The products have not been properly evaluated and can pose serious health risks, the agency says

(CNN)The US Food and Drug Administration is cracking down on companies it says are making unsubstantiated claims that certain products made from marijuana can cure cancer.

This week, the agency responsible for policing the American food and drug market issued warning letters to four companies that are "illegally selling products online that claim to prevent, diagnose, treat, or cure cancer without evidence to support these outcomes." It said in a statement, "The illegally sold products allegedly contain cannabidiol (CBD), a component of the marijuana plant that is not FDA approved in any drug product for any indication."
