For products made with CBD from hemp, even Colorado doesn’t require testing of the finished product. So any COA for those final products comes from testing the company arranged on its own. Though not all manufacturers take that step, many do, Lanier says. That includes even some companies that use imported hemp, such as CV Sciences, which makes Plus CBD Oil from hemp grown in Holland.
Overall, based on my personal HempWorx CBD oil review I would probably recommend HempWorx for people who have been (or plan on) using CBD as a routine daily treatment. Their 750 CBD oil was pretty effective for may anxiety and panic attacks, and it definitely helped me get to sleep in the evenings where I was having more intense episodes than normal.
