Potency and safety analysis of hemp delta-9 products: the hemp vs. cannabis demarcation problem.

Background: Hemp-derived delta-9 tetrahydrocannabinol (∆ THC) products are freely available for sale across much of the USA, but the federal legislation allowing their sale places only minimal requirements on companies. Products must contain no more than 0.3% ∆ THC by dry weight, but no limit is placed on overall dosage and there is no requirement that products are tested.

Coping, meaning in life, and quality of life in congestive heart failure patients.
