couchtater, please familiarize yourself with the rules. They are known to change periodically. As this has become legal in several states, it is to only be discussed for medical purposes, any recreational use discussion is forbidden.
As to answer the question, I have used it in the past before being put on transplant list and it has helped a lot with pain. It doesn't last very long but safer than chemical pills in my opinion. If you are not a fan of smoking, you can always get the food products or make them yourself!
