Stop in for a cup of coffee

It's an oil extracted from Marjuana. It's legal for use medically in some states. Others it's not. It has no THC. There's been a huge movement on the medical side to get the FDA to make it 50 state legal as studies are producing better results than any prescription drugs for a variety of treatments. Including cancer and siezures
Also, FDA cannot make it 50 State legal. They can only approve a drug product after sufficient clinical studies have been done by a sponsor and then a New Drug Aplication made. After that, if it is approved, only that sponsor can manufacture it for sale through the prescription drug channel. Also, the application is only for the condition studied clinically.

Also, if anyone gets CBD oil approved, all of the other shops selling the stuff will be immediately subject to being shut down by the FDA and banned from selling an illegal prescription drug product.
