Addiction is a chronic brain disease that entails constant seeking and use of drugs, irrespective of the resulting effects. Drugs alter the functions and structure of the brain. Some of the effects on the brain may have long-lasting consequences on an individual leading to risky behaviors.
Addiction and other ailments like heart diseases have similar characteristics. Both conditions affect the standard functions of the body organs. Also, one can prevent and treat both disorders. However, if the diseases are not addressed, they may have a lasting effect on an individual.

It is imperative to note that moderate consumption of drugs is equally harmful and risky.
The decision to consume drugs is considered voluntary. Continued use of drugs may soon get out of control causing severe impairments. Imaging studies about the brain of individuals addicted to drugs reveal physical alteration to the areas responsible for decision-making, judgment, control of behavior, memory, and learning. Scientists believe that these changes may elucidate on the destructive and neurotic behavior of addiction.
Reasons That Some People Get Addicted to Drugs, and Others Don't
The home environment during childhood may determine one’s susceptibility to consumption of drugs. Also, members of the family who abuse drugs or are involved in criminal activities may result in children having a drug problem in the future.

People diagnosed with mental disorders and adolescents have a higher risk of addiction relative to the general population.

The addictive potential is catalyzed by smoking and injecting drugs into the veins. This way, the effects of the drugs get into the brain quickly. Scientists believe that people continue to take drugs repeatedly to enjoy the pleasurable state for a more extended period.

This region continues to mature during adolescence. Adolescents may make poor choices, as the prefrontal cortex is not fully mature. Introduction of drugs before the cortex is fully mature may result in brain changes. These changes may have profound consequences on an individual.
