I think the Myrcene is helping me, although it could be placebo. But no overall I don't think so. The placebo effect only lasted for one day for me when I started on low dose methylphenidate, so due to that I think any plaebo effect with these products would also have gone by now.
These CBD oils I'm using are diluted in "organic olive oil", I cant remember exactly what the ratios are but IIRC I think I read or heard something like 80% to 20% of oil to CBD, respectively. There's another company that are using CBD Hemp oils (again, IIRC) as their carrier, instead of olive oil, and claiming that this makes their product the most naturally broad spectrum CBD possible.
I guess it could be.
But at the moment I'm quite happy with the products I've found, they certainly seem to work, and are noteably strong, to the extent that I had a very minor transportation accident, after dosing in the morning before setting off. I very much doubt that would have happened otherwise.
I now only dose after work in the evenings. It's possible to get a less potent oils, and I have some which is about 1/4 of the strength. I've not tried it yet but it should be more suitable for daytime dosing. Thats one of the issues with dosing with "drops" out of pippetes though - it's so innacurate and random. I mean, how much is a fucking "drop"?
A video from the hemp oil people mentioned that they do gradated pippetes, and that 1/4 of the pippete = such and such a dose etc. It might be worth trying them at least once, to get one of the gradated pippetes.
One thing that I find interesting is that the CBD products are said to be much more effective when used in combination with full spectrum THC weed. And they also make the THC experience more enjoyable IME.
All good news considering that it seems very difficult to find high CBD/Myrcene types of weed on the black market. They only seem easily available via the prescription only medical route. But it definitely seems you can go someway towards making your own tweaks to the effects, as you said above.
Apparently theres just not much demand for high CBD weed on the black market and so they are not profitable for the black market sellers. Most people just want high THC.
