Does pure CBD actually work?

I'm curious to know, does pure CBD really work? With so many claims and counterclaims out there, it's hard to separate fact from fiction. I've heard it can help with anxiety, pain relief, and even sleep issues, but I want to hear from someone with expertise in the field. Can you tell me more about the scientific evidence behind pure CBD and its potential benefits? Are there any side effects or precautions I should be aware of? And finally, how does pure CBD compare to other forms of CBD, such as those found in supplements or topical creams? I'm eager to learn more and make an informed decision about whether pure CBD is right for me.
