I have/do use it. Although i dont use it for pain, i was hoping it would help with anxiety, but it didnt. I still use it though because i found it gave me some much needed cognitive/memory improvements that my other meds were wreaking havoc on.
You must be VERY careful with it though. CBD consumed orally uses the same enzyme in the liver to metabolize as a lot of the meds, which means that i can significantly raise or lower the amounts of the other meds you may be using.
I found this out the hard way when first time i used it i had a near emergency level spike in serotonin because of the mirtazapine i take. It was bad, but i rode it out, it took about 6 hours for it to dissipate.
As well, some CBD does has up to the federally allowed max of %.3 THC.
THC definitely is bad with any anti-depressant and for sure any anti-psychotics.
Be sure to purchase one that clearly states "THC Free".
Also be sure to source it from a reputable supplier. CBD right now is like the wild west and there are many questionable suppliers out there.
Some of the good ones are VerifiedCBD, Green Roads, Charlottes web, and Koi.
