Haircuts: For both Amritdhari and Keshdhari Sikhs, cutting or removing hair (kesh) from any body part is strictly forbidden, including the shaving or trimming facial and nostril hairs. Intoxication: Consumption of drugs and alcohol is not allowed for Amritdhari and Keshdhari Sikhs. Sahajdhari Sikhs do not hold these precepts, but generally avoid alcohol. Marijuana and tobacco are not accepted within the Sikh community as a whole and are strictly prohibited for Amritdhari Sikhs. Gambling: Gambling (jooa), be it in any form—such as lottery, roulette, poker, american bingo or british bingo—is prohibited in some 'codes of conduct', such as the Sikh Rehat Maryada. Blind spirituality: Idolatry, superstitions, and rituals should not be observed or followed, including pilgrimages, fasting, and ritual purification; circumcision; idol or grave worship; and compulsory wearing of the veil for women. Observation of the five Ks, however, is not considered blind superstition, as they are intended to help Sikhs in their everyday life. Material obsession: Obsession with material wealth is not encouraged in Sikhism. Sacrifice of creatures: Animal sacrifice to celebrate holy occasions are forbidden. Non-family-oriented living: Sikhs are discouraged to live as a recluse, beggar, yogi, monastic (monk/nun), or celibate.[citation needed] Worthless talk: Bragging, gossip, lying, slander, "backstabbing," et cetera, are not permitted. The Guru Granth Sahib tells the Sikh, "your mouth has not stopped slandering and gossiping about others. Your service is useless and fruitless." Priestly class: Sikhism does not have priests, as they were abolished by the 10th Guru of Sikhism, Guru Gobind Singh. The only position he left was a Granthi to look after the Guru Granth Sahib; any Sikh is free to become Granthi or read from the Guru Granth Sahib. Eating meat killed in a ritualistic manner: Sikhs are strictly prohibited from eating meat killed in a ritualistic manner (such as halal)—or any meat where it is served[clarification needed], except jhatka meat. For many Sikhs (excluding some small Sikh sects, e.g. Akhand Kirtani Jatha) eating any meat cooked by Jews (i.e., kosher) and Muslims (i.e., halal) is believed to be forbidden. Extramarital sexual relations: Adultery is prohibited; Sikhs are not allowed by their faith to cheat on their spouse. Cutting turbans whilst worn: Cutting turbans too short when worn (excepting excessive material) will be damaged by scissors as it is strictly forbidden the same way as cutting hair[clarification needed]. Swimming water through turbans: Swim caps are a different head gear to wear as a substitute to turbans when all Sikhs go to swimming pools at leisure centres
