What Illegal addictive stimulant made from coca bush leaves?

The illegal addictive stimulant made from coca bush leaves is cocaine. Cocaine is a powerful stimulant drug derived from the coca plant, native to South America. The coca leaves are processed and refined to extract the psychoactive alkaloid cocaine. It can be taken in various forms, including powder, crystals, or "crack" cocaine, and it exerts its effects on the central nervous system by blocking the reuptake of certain neurotransmitters, resulting in increased levels of dopamine and other neurochemicals that stimulate the brain's reward system. Cocaine is highly addictive and poses serious health risks, including potential cardiovascular problems, seizures, psychosis, and addiction. Its illegal status in most countries reflects the significant harm associated with its use and its potential to cause dependence.
