Detailed answer
WHO classifies CBD as broadly safe and non-addictive. Common side effects (>1 % of users): fatigue, dry mouth, appetite changes, diarrhea, mild blood pressure reduction. Rare: liver enzyme changes at very high doses (>500 mg/day). Interactions: CBD inhibits cytochrome P450, which can raise levels of blood thinners (warfarin), antiepileptics, some antidepressants and immunosuppressants — consult before combining.
