The Sikh Code of Conduct is a guide that was published by the SGPC (Shiromani Gurdwara Prabandhak Committee) in 1950. It provides details of how Sikhs should live. It forbids the use of tobacco, cannabis, opium, cocaine and alcohol or any other substance that can affect the mind and so prevent a Sikh’s worship of Waheguru [Waheguru: A Punjabi term used in Sikhism to refer to God. ].
Anyone who wishes to visit a gurdwara (place of worship) is welcome as long as they have no traces of alcohol or tobacco on them.
