I have back lower back pain; have had it since August of 1973. Today I took the plunge and purchased a 15cc (one-half an ounce) bottle of CBD oil extracted from hemp. Total price, to include the rapacious sales tax in Washoe County, was ninety-seven bucks. I was told to use it before going to bed and after the next morning's shower; was told the therapeutic effects hang in there for approximately twelve hours. Has anybody within these pages also tried CBD oil? Mine has 30mg of the oil per cc of the liquid; 450 mg total which I've read is pretty heavy with the stuff we want. I'd like to read about any other's experiences with CBD.
