Addiction is A Disease

Something that has been controversial (and to some extent still is) within the mental health community is whether addiction is a disease or a choice. There has been a wealth of research over recent years that has really pointed in the direction that addiction is an actual disease.

Three years ago the United States surgeon general publicly asserted his position that addiction is a disease and not a moral failing.

We know now that addiction is a disease because it makes actual physical changes in the brain that make addicts prone to addictive behaviors. Much like how someone with diabetes cannot simply choose to not need insulin, an addict cannot simply choose to stop being an addict without having negative, often terrible, side effects. The diabetic can follow a strict regimen of medication, exercise, and diet, and experience a significant reduction in symptoms. Similarly, the addict can do things to better his/her condition but cannot simply make their addiction disappear at will. If you’ve ever known an addict you might have thought “why can’t they just stop?” This is why.

Addiction hijacks the brain’s natural hierarchy of needs. We are wired to value/prioritize things that are more important to our survival over things that are not. In this way, eating is much more important to the brain than say watching a movie, for example. So naturally, when deprived of both movie watching and food, the brain will urge us to eat, but not so much to go see a movie. Addiction takes over this hierarchy and places the substance of abuse above all else. This results in a situation, much like breathing, in that you can choose to hold your breath for a long time, but eventually your brain will implore you to breath, and you will give in. This is how a person in the throws of addiction experiences cravings.

Some people think of addiction as being a choice rather than a disease because diseases like diabetes make actual physical changes in the way the body functions, and thereby alters the person’s health. We now know that addiction makes physiological changes to the brain. This part gets a little complicated.

All pleasurable experiences, no matter what they are; sex, drugs, eating cookies, whatever, give you that pleasurable experience by releasing a neurotransmitter called dopamine into key areas of the brain. The difference between say eating an apple and eating a cookie is essentially the amount of dopamine available to special receptors in these areas that pick up dopamine. Think of it as if dopamine is the key, and the receptors are the locks that unleash pleasure. When you eat an apple a few locks are unlocked. When you eat a cookie, more locks are unlocked. If you take heroin, or whatever your drug of choice is, a whole bunch of locks are unlocked. This is where the physical change comes in. Human beings are amazing homeostasis machines. The brain generally will do whatever it can to maintain homeostasis. So, when you take heroin and the brain becomes flooded with dopamine, over time the brain’s response is to reduce the actual number of dopamine receptors in the pleasure areas of the brain. This means that regularly pleasurable things like cookies, sex, reading a book, etc., are no longer able to stimulate the brain in a way that produces feelings of pleasure. In this way, addiction is a disease of the brain’s ability to experience pleasure, also known as anhedonia.

I think it helps to think of it like this: imagine you’re standing over a board with a couple dozen randomly spaced holes that are slightly bigger than a marble. When you eat a cookie you drop a hand full of marbles and a couple get through the holes. When you take a drug of abuse it’s the equivalent of dropping a bucket full of marbles, and hundreds of them getting through the holes. Too many are getting through, so to compensate, you plug some of the holes. Now a handful of marbles doesn’t really get anything through, but a bucket gets a good amount. At some point you get rid of the bucket and go back to using a handful of marbles (because using a bucket to pour marbles is clearly addictive behavior). Now you have a horribly slim chance of getting any marbles through the board because there are so few holes now.

This is how addiction works in the pleasure centers of the brain. After extended use of an intoxicant, the brain adapts in a way that makes a person dependent on the drug. Over time, while abstaining from drug use, the brain can heal from this. However, studies have shown that the brain somehow remembers being addicted, and if a person in recovery uses again after a long period of abstinence, the brain is more quick to make these changes than in a person who was never an addict.

When I was in grad school I heard an amazing lecture by Dr. Kevin McCauley, who has been very influential in growing the disease model of addiction. I really wanted to share that lecture with you, but I was unable to find it. The following is another good lecture of his. It talks about the specifics of why addiction is a disease. If you want to learn more you should really listen to it sometime. He does a good job explaining everything, so you can listen to it without seeing his slides.

If you or someone you love are struggling with addiction, therapy can help. SacWellness is home to many therapists who specialize in substance abuse and addiction. SacWellness is a website designed to help people find therapists in the greater Sacramento area. Therapists on the site are located in the areas between Davis, Elk Grove, El Dorado Hills, and Auburn
