I am an adult with ADD and several other conditions. I have been taking CBD for several months now. I has helped me to concentrate better, work smarter and stay organized. I purchase my CBD from an online distributor that test all of their products to make sure there are no unwanted thc or other potential harmful ingredients. Lazuras Naturals is where I get mine. Not only has it helped with my ADD it has helped me with most of my other conditions and toned down the rest. I take mine in the a.m. and p.m. .25mg each time.
