The predilection for addiction is in our genetic makeup. We can deny all we want, but every human being has the hard wiring to become addicted to something . . . or multiple somethings. Even so, this isn’t to say that all people will become addicted to something or anything in their lifetime. Addiction can also occur for a variety of reasons, and various contributing factors come into play. Below is more on the addicted brain and how it compares to one that’s not.
Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters in the brain. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure is similar to that of a natural neurotransmitter in the brain. This allows the drugs to attach to and activate neurons.
Although these substances mimic the brain’s chemicals, they don’t activate neurons in the same way that neurotransmitters do. They also lead to abnormal signals sent through the body, causing various reactions or side effects. Other drugs, such as amphetamines or cocaine, can cause neurons to release abnormally large amounts of natural neurotransmitters – like dopamine – or prevent the normal recycling or reabsorption of these brain chemicals by interfering with transporters.
Drugs and addiction affect three major areas of the brain: the basal ganglia, the extended amygdala, and the prefrontal cortex.

This motivational reinforcement manifests as a craving and contributes to the overwhelming desire to seek and use. It’s actually thought that cravings for drugs and alcohol are more an attribute of desire than the actual feeling of pleasure. In other words, the anticipation of pleasure is greater than the actual sensation of pleasure, and craving is what motivates drug-taking behavior.
As a result, the addicted brain learns to receive pleasure from following events or cues that stimulate desire. The pleasure linked to anticipation becomes over-inflated, hijacking the reward system. Eventually, the normal pleasure pathways are rewired as the chemical disease progresses, feeding the addiction by inflating the reward and pleasure associated with the anticipation of the substance. This anticipation becomes almost as rewarding and pleasurable as using the substance itself.
The nucleus accumbens is an area of the brain associated with pleasure, and the ventral tegmental area is a midbrain structure that projects dopamine into the nucleus accumbens. The stimulation of the ventral tegmental area, followed by the stimulation of the nucleus accumbens, plays a major role in substance abuse and dependence, as essentially all addictive substances stimulate these areas.
Even at rest, an addicted brain is different from a normal brain. For instance, when heroin abusers and their matched controls were asked to remain quiet with their eyes closed, there was more spontaneous activity between the areas of reward, like the nucleus accumbens, ventral tegmental area, and orbitofrontal cortex. The brain of an addict also shows a reduced sensitivity to dopamine, which could result in a desire and motivation to increase dopamine levels via drugs or alcohol.
Many see addiction as a moral failing on the part of the addict, and it’s in these cases that those struggling with some type of substance use disorder rely on self-medicating rather than reaching out and asking for help. The bottom line is that addiction is real. What’s more, addiction is a disease that can affect anyone.
