The potential consequences of performance-enhancing drugs include severe health risks and strict sanctions from sports organizations. Athletes may face short-term effects like increased strength or endurance, but long-term use can lead to serious health issues, including cardiovascular problems, hormonal imbalances, and mental health challenges. Furthermore, being caught using such substances can result in suspensions, damage to reputation, and loss of sponsorship deals. This not only impacts an athlete's career but can also tarnish the integrity of the sport, undermining the principles of fair competition and hard work.
