I have chronic pain due to arthritis in my lower back. I live in a State that has medical marijuana. I don't have a card from the State yet, so I buy from the recreational side of the State approved dispensaries. I started with the oils, no help. Then tried CBD buds, but they had a low amount of CBD, only 11%. It took a few months before I found what I think might work. It's a vape pen and cartridge (battery). It has 68% CBD, and only 4.5% THC. I've only been smoking this for about a week, but I'm hoping at some point it will help with my arthritis. The cartridge is from "Freedom Pen". We have to pay a hefty tax on all CBD products, but I think it's worth it because everything sold in the State approved dispensaries has been approved by labs in the State I live in. Good luck everyone.....AChronicPainer
