Yeah, if there is no leeway in the testing not worth risking it. However, I do know, around here anyway, that some CBD shops are pretty professional and understand that certain people cannot test positive and they provide pretty good advice and technical information. But I don’t think I would trust the manufacturer if my job was on the line. I didn’t have to worry about that aspect so I used the full spectrum stuff. If you have bone on bone happening, I doubt that CBD is going to work miracles anyway.
