The introduction of drug abuse is the initial stage in which a person first starts to use drugs. This can happen for a variety of reasons, including curiosity, peer pressure, or even just wanting to fit in. Once a person begins using drugs, they may start to feel the need to use them more and more frequently in order to achieve the same desired effect. This can lead to addiction, which is a chronic, relapsing disease characterized by compulsive drug use despite negative consequences.
