I have heard that a Doctor's prescription of Marinol will provide the same benefits with the protections of the FDA approved supply chain. Unless the State that you live in has superb oversight over the new marijuana industry, the FDA is not operating in that lane, and therefore I would not trust what is said to be inside these products.
The FDA has recently approved CBD oils in some food products under the farm bill, and those are inspected if they are properly labeled. As for potential cancer cures, this is an absolute NO/GO. Cannabinoids do help with nausea and will make you feel better as previously stated. Just one person's opinion.
All the best!
