The Causes and Effects of Drug Addiction

Drug addiction is not a hallmark of moral failure or lack of willpower—it’s a complex disease that deserves long-term, extensive treatment, just like any other chronic condition. People who have not struggled with substance abuse may find it difficult to understand why anyone would start using. Why would someone willingly put themselves in harm’s way by taking dangerous substances? There are, in fact, many reasons why some people turn to or start abusing drugs, and unfortunately the consequences can be life-shattering. While every case is unique, there are general patterns that indicate why some people use drugs, how addiction develops, and the consequences of drug abuse.

Why People Use Drugs
While specific incentives differ from person to person, generally speaking, people start using drugs to escape or mask pain.
In some individuals, the onset of drug use can be from untreated psychiatric issues including anxiety and depression. The rush of pleasure from using drugs can provide temporary solace from suffering, which can stem from many mental health or other issues including the following:

Trauma or abuse
Mental illness
Low self-esteem
Poverty
Relationship problems
Loss of a loved one
Stress
Chronic pain or medical conditions
But whatever their reason for starting, once addiction sets in, the disease usually spirals more and more out of their control.

How Addiction Develops
For most people, the initial decision to take drugs is voluntary. But as they are swept up into the cycle of addiction, the neural pathways in their brain change so they are less able to control their behavior and resist their intense impulses.
It works like this: the brain rewards pleasurable experiences (such as food, intimacy, and laughter) with surges of feel-good chemicals like dopamine. But using drugs triggers the release of much more dopamine than chocolate or cuddling does, and the rush of euphoria compels them to repeat the experience. The more someone uses drugs, the more they condition their brain to anticipate the same substance-fueled pleasant sensations.
That’s why it’s so difficult to stop. The brain becomes wired for addiction. Eventually, one’s tolerance may build so much that addictive behavior no longer provides any pleasure, and using drugs simply becomes a way to avoid withdrawal. They need drugs just to keep feeling normal.
