The cause of drug abuse and dependence is unknown, although there are a variety of theories. One theory holds that there may be a genetic component that predisposes a person toward using and abusing drugs. Another theory is that drug abuse is a learned behavior and that people begin to use drugs by copying the behavior of those around them. Medical professionals have not been able to target a specific cause.
Brain chemicals may alter the user's perception of the drug's effects. Long-term drug use changes brain function and may reinforce the desire to keep using drugs regardless of the consequences.
Chemical Release in Brain
Drugs stimulate unnecessary chemical release in the brain. Used long-term drugs may actually change brain function.
