Smoking is bad on its own, but I wouldn’t recommend CBD either, if you are considering other ways to take it. It is too similar to THC. Some CBD will also contain a little bit of it. There was a similar post and I’ve talked about it before.
I would consider why you want to take it and look for alternatives. Most people take it for relaxation or pain relief or anxiety relief. Why not meditate or do yoga to achieve the same effects? It may not be instant but you’ve advanced yourself in the process instead of becoming dependent on an outside substance.
