Remember, it's the combination that works.
CBD throttles a bit the effect THC has.
You should be looking for the right CBD-->THC proportion.
Everybody's body responds differently.
It's not that it doesn't work for you.
I'ts that CBD, by itself, is not enough.
The gamut runs from 1:1 to about 20:1. (THC:CBD).
You have to find out which proportion works for you.
I'd start with a 3:1 proportion, and move up or down depending on the results.
