In my experience with CBD, it, by itself doesn't work at all. I was approved for medical marijuana and use the oil that is mixed with CBD oil and that works far better. They have different strains and strengths so, if you are easily affected like I am, you would use the weakest strain or the one with less THC . It doesn't cause hallucinations or anything like that. They offer sativa, hybrid or indica. Sativa gives you more energy and is uplifting. Indica helps more with pain and sleep issues. I was just approved for the choice to use one with higher THC and that will help with sleep and pain. I'll repost after I use that. I'd just save your money when it comes to CBD alone.
