Has anyone tried CBD oil ?

I'm contemplating on whether I should try this CBD oil that a friend suggested. There are many benefits to this oil, and the one that stands out for me is the fact that it may reduce anxiety and depression, which I suffer from. I've been a consistent marijuana smoker for many many years, and since I'm about to be a parent I'm trying to quit and ween off from my daily usage, and try out this CBD oil. Does anyone have experience with this stuff? Is it effective? Safe?
