Hi, My son was taking treatwell 20:1 cbd to THC. Inotherwords about 10mg CBD and 1 mg THC so he would not get high. Unfortunately treatwell went out of business. I just saw a gerontology nurse practitioner who specializes in using CBD with her patients including those with psychiatric conditions and autism. We are switching brands so I will let this discussion group know how it goes with the new one she suggested. It is mail order only but less expensive which is good because I do not know of any insurance companies that will cover the cost. . Currently using temporarily Sweet Jane CBD 20:1 but I am not sure it is as effective. From lectures I have attended the product can vary a bit sometimes since it is made from a plant and not a pharmaceutical process
