Happiness and contentment are often described as emotions that come from deep inside the heart. In reality, these are states that come about due to chemical changes deep inside the brain. Those chemically induced feelings can be brought to life through drug abuse. Cocaine is one of the most effective pleasure-inducing drugs available to drug users.
The National Institute on Drug Abuse (NIDA) reports that cocaine brings about pleasure by tapping into a part of the midbrain known as the ventral tegmental area. When this part of the brain is augmented and changed, people feel intensely happy. They feel as though the change is rewarding and worth repeating.
That is what makes cocaine so addictive. People can come to that addiction via one of the two formats of cocaine. One is a powdered form of cocaine, typically called simply cocaine. The other is a glassy, rock-like form of cocaine, typically called crack. The two share many similarities, but there are a number of differences worth noting.
