Coca is a plant native to South America, primarily found in countries like Peru and Colombia. The leaves of the coca plant contain alkaloids that can be processed to produce cocaine, a powerful stimulant drug. Traditionally, indigenous people have chewed coca leaves for their mild stimulating effects and to alleviate hunger and fatigue. Cocaine is often used recreationally for its euphoric effects, but it is illegal in many countries due to its potential for addiction and harmful health effects. The drug can lead to serious physical and psychological issues, including heart problems and anxiety, making its use highly risky.
