The straight edge movement is a social movement that emerged in the early 1980s, primarily within the punk rock subculture. It promotes a lifestyle free from alcohol, tobacco, and recreational drugs, emphasizing personal responsibility and health. The movement often advocates for vegetarianism or veganism as part of a broader commitment to a clean and ethical lifestyle. Members of the straight edge community often identify themselves with the symbol "X" marked on their hands, which signifies their commitment to abstaining from substances. The movement has inspired various bands and artists, contributing to its growth and influence in alternative music scenes.
