I started importing CBD extract from PharmaXtracts in the vaping cartridges a few months ago to treat chronic back pain I've suffered on and off for at least the last 10 years (I have a nasty habit of repeatedly pinching back nerves in the gym).
While it did sort of work, I found I had to vape so much that it soon became too expensive to continue long term.
I just went back to smoking full spectrum weed from the black market, which is not only cheaper for me, but IME works way better for my pain relief due to the "high" helping me disassociate from the pain.
The other thing is the CBD would take a bit longer for me to notice any improvement, whereas with THC/CBD I feel better within 5 minutes.
