Ok i see, im planning on making oil for ingestion. Well i have no lab which can test the thc. Fadedawg yes i have also heared about that cbd can give painrelief but it doesn't work on me. Though i think cbd oil with a small amount of thc could help me.
Without numbers from lab tests, the next best thing is probably titration. The two oils don't have to be mixed to achieve the intended goal, so I suggest that you take the CBD and THC oils separately.
Take one full dose of CBD oil, and work your way up with the THC extract dosage.
Tolerances vary considerably, but around 100mg of RSO is typically about one good dose for an average tolerance person. As some people OD at far lower doses, I suggest starting around 25 mg and titrate up.
Once you establish the ratio that works for you, mix the two together at that ratio.
