Drinking alcohol can seriously harm one's life in several ways. It is the most commonly used drug worldwide and has been shown to cause cancer. When drinking and driving, alcohol impairs visual abilities, decreases reaction time, and increases risks. Drinking also negatively impacts physical performance by slowing reflexes and coordination. The legal drinking age varies by country but is 18 in most European nations. In Italy, over 40% of those aged 18-24 report drinking, and alcohol is implicated in about one-quarter of deaths of those aged 15-19. Italian law tightly regulates alcohol sales and advertising to minors due to health and safety concerns.
