While it is not necessary to use cannabis to be a Rastafari, many use it regularly as a part of their faith, and pipes of cannabis are dedicated to His Imperial Majesty Haile Selassie I before being smoked. According to the Watchman Fellowship "The herb is the key to new understanding of the self, the universe, and God. It is the vehicle to cosmic consciousness" and is believed to burn the corruption out of the human heart. Rubbing the ashes into the skin from smoked cannabis is also considered a healthy practice.
