This is a list of notable people who follow the straight edge lifestyle. Straight edge is a subculture and subgenre of hardcore punk whose adherents refrain from using alcohol, tobacco, and other recreational/non-prescribed drugs. It was a direct reaction to the sexual revolution, hedonism, and excess associated with punk rock. For some, this extends to not engaging in promiscuous sex, following a vegetarian or vegan diet, and not using caffeine or prescription drugs.
