Is CBD Oil Safe?

Yes, but only for CBD used as a food supplement, and only as a provisional value. In February 2026, the European Food Safety Authority (EFSA) set this level at 0.0275 mg per kilogram of body weight per day; for a 70 kg adult, that comes to about 2 mg a day. The value applies only to supplements that are at least 98% pure, contain no nanoparticles, are produced in a way judged safe and have had the risk of genetic damage ruled out. This is an agency assessment and it is based on animal studies: it was calculated from an increase in liver weight seen in rats, leaving a 400-fold safety margin. It was kept provisional because information on possible effects on the liver, nervous system, hormones and reproduction is still missing; EFSA will review the value when new data come in. Safety could not be established for people under 25, women who are pregnant or breastfeeding, and people taking medicines. This number is an upper limit calculated by the agency; it is not a personal dose recommendation or an amount you should take, and it does not count as permission to sell (when the opinion was written, no CBD product taken by mouth had been authorized as a novel food in the European Union). The approved CBD medicine is outside the scope of this assessment; its doses are assessed separately, as a medicine, and are set by a doctor. If you take medicines, you can check the drug interaction tool and talk with your doctor (Source: EFSA, February 2026).
