I went to a seminar on Hemp CBD oils (which are now fully legal in the USA) So I bought an $80+ little bottle of hemp oil (this one) www.hemplucid.com/collections/all/products/mct/?attribute_pa_strength=500mg
from the lady who was teaching the seminar. I learned a bunch about CBD's from her and began taking 4 drops of the oil daily. I have to say that the use of CBD oil has sharpened my brain up a bunch, and it totally eliminated my finger bone joint problems from guitar practice, and mitigated the other arthritic joint problems to minor irritation instead of sharp pains. Of course I bought the next dose on line for about 20 bucks less as indicated on the link above. The bottle is only a small bottle but I have been taking 6 drops of it daily for about 2 months and I still have half a bottle of the first bottle left. I also learned that just because it is CBD it is not necessarily the best option, so going to the seminar I learned the difference in how the CBD was extracted from the hemp plant and the CO2 extraction is the best (she said) which the bottle above is done in that way.
The one thing she taught me was that our bodies have natural cannabinoid receptors because we as humans have always ingested the hemp and marijuana plants as a matter of course. It has only been since the 1930's or so that it has been outlawed in the USA and other developed countries, and our bodies are starved for that kind of intake. At first for the first week or so, the CBD oil acted like a slight dose of speed until my body got used to it. So I do take my dose early but it no longer has that speedy effect on me.
