What we know -- and don't know -- about CBD

Hosted by

CBD is a cannabis extract that doesn’t make you high. You can buy it as a balm, spray, mint or oil. It’s not cheap -- a CBD lotion or oil can set you back $50-$80. The wellness industry markets CBD as a miracle drug that can cure everything from headaches to depression. But a lot of those claims aren't backed by science, and there’s a lot we don’t know yet about CBD.
