In practice, selling CBD seems to be legally riskier than possessing it. The DEA’s priority seems mostly to concern commercial violations; most cases involved smoke shops and non-cannabis vape stores selling CBD cartridges. In 2015, police seized CBD cartridges at a vape store near Milwaukee, but the store owners were never arrested or charged. (A 2014 law made it legal for patients to possess and use CBD oil in Wisconsin, but the law did not make it legal to sell.) That same year, police in central Florida arrested the owner of a local smoke shop chain for selling CBD products. 
I’d love to hear how it worked for you! I’m sorry you have renal failure and congestive heart disease, my mom who is 51 has stage 5 renal failure and congestive heart disease as well, I just bought a cartridge with CBD vape oil and want her to try it. But she’s unsure so I’d really love to hear from you how it may have helped you. I hope things get better for you. I take care of my mom and know the daily stress and struggle it can bring. Again I’m sorry to hear you we’re diagnosed with those diseases.
