I haven’t been on this site for awhile. I have had 3 back surgeries and 3 compression fractures within the past 3 years. I have had moderate chronic pain in my lower back. I started using CBD last Sept. I use the tincture but don’t hold it under my tongue very long. The rule is start low and go slow. I started at 1 dropper (0.8 ml) of 1000m/30 ml strength. Increase no more often than weekly. I take mine, currently about 50 mg per dose every 4 hours while awake. It took awhile but my pain decreased by 50%. People quit early but need to keep increasing the dose for relief. I’m a retired hospice nurse and volunteer once a week and golf twice a week. Not great but much better. I did get my MM license but have not been able to find a product concentrated enough and would have to drink a half bottle. Good luck. - Margit
