…Smoking is not forbidden by ‘Abdu’l-Bahá; He advises against it for reasons of health, but we have no right to prevent anyone from smoking. But drinking and the use of drugs are strictly forbidden and the Bahá’ís should obey this command.
- Shoghi Effendi (From a letter dated 26 February 1947 written on behalf of Shoghi Effendi; ‘The Light of Divine Guidance, vol. 1)
