Cocaine is a stimulant that, when inhaled, snorted, or injected, makes its way to the brain through the bloodstream. Once in the brain, it interferes with the brain’s normal processes including the mesolimbic dopamine system, recognized as the pleasure center of the brain. This interference results in creating a euphoric sensation along with feelings of alertness, increased energy, and elevated heart rate.
Cocaine usually appears as a white, powdery substance and can be consumed by smoking, snorting, or injecting into a vein after being dissolved in water.
Though the highly addictive nature and harmful side effects of cocaine are widely known and studied, it still attracts millions of users in the US. According to the National Survey on Drug Use and Health, there were an estimated 1.9 million active cocaine users in the United States in 2015.
