What does the European food-safety assessment say?
In February 2026, EFSA set a provisional level of 0.0275 mg/kg/day, about 2 mg for a 70 kg adult. It applies only to supplements with at least 98% pure CBD, no nanoparticles, a safe production process and excluded genotoxicity (potential damage to genetic material). Safety could not be established for under-25s, pregnancy, breastfeeding or people taking medicines. This is a narrow food-safety assessment, not a treatment dose. 1
What adverse effects are known?
The prescription medicine can cause drowsiness, diarrhea, reduced appetite and increased liver enzymes. Its medical use includes liver monitoring. 2
Why a medication check matters
The product information identifies greater liver-enzyme risk with valproate and, to a lesser extent, clobazam. Alcohol and other sedating substances can intensify drowsiness; impaired alertness also matters for driving. 3
