How can Cocaine and Heroin be effectively classified?

When we talk about Cocaine and Heroin, it's crucial to understand their fundamental nature. These substances are derived from plants – cocaine from the coca plant native to South America, and heroin from the opium poppy. However, the key thing is that both are heavily processed and used in ways that drastically alter their effects on the human body. They powerfully affect the brain's reward system, leading to intense cravings and addiction. Because of these effects, and the significant health risks associated with their use, including overdose and long-term organ damage, they are strictly controlled under UK law. They aren't medicines because they lack therapeutic benefits and pose significant dangers. They're also obviously not places or hotels. Therefore, the only accurate classification for both Cocaine and Heroin is as drugs, specifically illegal and highly addictive ones.
