The "hemp seed oil" that I buy in the store (marijuana store,
licensed by the state) in the state of Washington, has THC in it. If you
buy hemp seed oil on-line or in a health food store you're going to get hemp
seed oil, but no THC. It is the THC that provides cures/benefits for such
things as cancer. It is unlikely that regular hemp seed oil provides any
benefits beyond what regular olive oil provides because it doesn't contain THC.
What I understand of Rick Simpson oil is that it is like what I buy - oil
with THC. However, in my state is is so much easier to buy than to make it
that I don't bother going through the Rick Simpson oil production process.
