This post was originally published in 2012 and is part of an ongoing review of past posts about the conceptual boundaries of addiction and its relationship to the disease model and recovery. In a thoughtful post, Marc Lewis questions the disease model of addiction. He doesn't dismiss it out of hand. He seems to look … Continue reading Response to Why Addiction is NOT a Brain Disease
Addiction and Free Choice
Nora Volkow, in the first two sentences of this post, provides more clarity than I think I've every seen on the matter of choice and the brain disease of addiction: Choices do not happen without a brain—it is the mechanism of choice. The quality of a person’s choices depends on the health of that mechanism. … Continue reading Addiction and Free Choice
More on choice and addiction
From Kevin McCauley: The argument against calling addiction a disease centers on the nature of free will. This argument, which I will refer to as the Choice Argument, considers addiction to be a choice: the addict had the choice to start using drugs. Real diseases, on the other hand, are not choices: the diabetic did … Continue reading More on choice and addiction
NA gives its members opioids?
Marc Lewis discusses an important role of endogenous opioids. Some very prominent emotion scientists have theorized that opioids (made inside our brains) are at the root of human attachment. Mother’s milk is rich with opioid molecules. In other words, nature found a surefire way to soothe the baby with its mother’s milk, using the same … Continue reading NA gives its members opioids?
Response to Why Addiction is NOT a Brain Disease

Methadone’s cognitive effects
Another study on methadone's cognitive effects: In one study, on the day after the last exposure to methadone, there was a significant reduction (around 70 per cent) in the level of a signal molecule which is important in learning and memory, in both the hippocampus and in the frontal area of the brain. This … Continue reading Methadone’s cognitive effects
Revenge and the reward system
I've often wondered about all of AA's emphasis on resentment and whether research will end up provide an evidence-base for all the attention it receives in the steps, literature and discussion. I found this, from a recent episode of On Being, very interesting: Mr. McCullough: And if you look at the brain of somebody who has just … Continue reading Revenge and the reward system
Emotional pain without context
Siddhartha Mukherjee provides a brief history of the serotonin hypothesis of depression, its demise and why dismissing serotonin may be an "overcorrection." Part of this story is an emerging theory of depression: A remarkable and novel theory for depression emerges from these studies. Perhaps some forms of depression occur when a stimulus — genetics, environment … Continue reading Emotional pain without context
How Exercise Can Prime the Brain for Addiction
This makes sense, but is a weird thing to think about. Drug addiction may be more difficult to kick if it became habitual while exercise if part of your routine: It does indicate that shedding an addiction acquired when a person has been exercising could be extra challenging, he says. “But, really, what … Continue reading How Exercise Can Prime the Brain for Addiction
