The BfR recommends acute reference dose as basis for assessing hemp-containing foodstuff

Tetrahydrocannabinol (THC or Δ9-THC) is a psychoactive cannabinoid that can be found in hemp-containing foods. Above a certain intake, the substance can have undesirable health consequences, such as mood swings and fatigue. In order to avoid the occurrence of such effects, the Federal Institute for Health Protection of Consumers and Veterinary Medicine (BgVV) recommended guidance values for maximum THC levels in various food groups in 2000. The guidance value for beverages was given as 0.005 mg/kg, for edible oils with 5 mg/kg and for all other foods with 0.150 mg/kg. In 2018, the BfR came to the conclusion that these values no longer correspond to current scientific knowledge.
