Can you tell me more about the efficacy, safety, and legality of Cannabidiol (CBD) oil?

I recently heard about CBD oil - that it can be effective for chronic pain and anxiety, both of which I've struggled with (and seen many specialists about) for years. But when I went looking for more information, I couldn't find many resources that looked like they came from legitimate, trustworthy sources. Can you shed some light on the subject?


Are there benefits to taking psychedelics?

I have two concerns:

My boyfriend claims psychedelics open your mind to new ideas/perspectives and help you experience the "spiritual world." I maintain that anything you see or think is just a result from a brain overloaded on chemicals. However, I am beginning to feel closed-minded, and I would like to have your opinion on psychedelics — are they beneficial if used for a one-time experience, and will they immediately/permanently alter the way I view the world and myself? Given that I have doubts, should I even try anything this mind-altering? I have read your answers pertaining to short-/long-term effects, but I wanted to know if there was any actual evidence of the beneficial effects.
