Hemp oil is non-toxic, and no known fatal overdoses have ever been reported. That said, too much of any good thing will make your tummy hurt.

The U.S. Department of Health & Human Services (2011) concluded, ‘no signs of toxicity or serious side effects have been observed following chronic administration of hemp oil to healthy volunteers (Cunha et al., Pharmacology 21:127- 185, 1980), even in large acute doses of 700 mg/day (Consroe et al., Pharmacol, Biochem, Behav. 40:701-708, 1991).’
