Here is my experience with RSO oil. I ordered from simpson-oil.com. They required a medical condition so I stated anxiety. They prescribed M1, the lowest THC they had. I explained that I'm 66 and have been smoking cannabis for 48 years and wanted to give my lungs a break. I asked to step up to more THC like M3 maybe? It cost me less than $195 for a small pouch. They said start with a tiny drop the size of half a short-grain rice. I put it on a Graham Cracker. Nothing. Over the next few week I kept increasing the size of the drop, still nothing, even a drop the size of a quarter, nothing. Next time I will need about 20x the THC than M3, if I would even order from them again.
