• Intoxicants – A Sikh must not take hemp (cannabis), opium, liquor, tobacco, cocaine, narcotics, etc. In short, any intoxicant is not allowed.
also he can't eat kebabs when he becomes Sikh
• Eating the meat of an animal slaughtered the Muslim or Jewish way (Kutha meat).[3] This is the absolute minimum required by all initiated Sikhs. Although vegetarianism is practiced and recommended by some Sikhs, many Sikhs refrain from eating non-vegetarian food, and believe all should follow this diet. This is due to various social, cultural, political, and familial aspects. As such, there has always been major disagreement among Sikhs over the issue of eating non-vegetarian food. Sikhs following the rahit (code of conduct) of the Damdami Taksal & AKJ also subscribe to this view. The Akali Nihangs have traditionally eaten meat and are famous for performing Jhatka.[4][5][6][7] Thus, there is a wide range of views that exist on the issue of a proper "Sikh diet" in the Panth. Nonetheless, all Sikhs agree with the minimum consensus that meat slaughtered via the Muslim (Halal), Jewish (Shechita) methods or any other religiously slaughtered way, is strictly against Sikh principles.
maybe he doesn't like kebab though. maybe sikhism is the religion compatible with British imperialism when it comes to meat consumption.
