Final answer:
The reasons for doping include heightened performance expectations, ethical conflicts, stringent regulations, and peer pressure.
Step-by-step explanation:
People's excuses to doping are often far-fetched and unbelievable. The reasons for engaging in doping include heightened performance expectations, ethical conflicts, stringent regulations, and peer pressure. Heightened performance expectations can drive athletes to resort to doping in order to achieve better results. Ethical conflicts arise when athletes face the temptation to gain an unfair advantage over their competitors. Stringent regulations in sports organizations prohibit the use of performance-enhancing drugs. Lastly, peer pressure can influence athletes to participate in doping activities.
