It’s not medical advice, it’s an opinion. And he’s right. It isn’t a “disease”, it is a weakness, a personal failing. You can blame the alcohol or the drug, but in the end, people choose to do what they do. Any recovered alcoholic or drug addict - the honest ones, anyway - will tell you that they, and they alone, were the cause of their addiction. Calling those things a “disease” implies that the addict is a victim of something over which they have no control. And that absolves them of their responsibility. Animals have no control over what they do, but people do.
Yours is a common opinion which I also shared at one time.
However, I’ve recently researched this question & learned the facts are somewhat different.
While it’s true that the initial decision to imbibe in addictive drugs is a bad *choice* which can be attributed to low character, in fact, it’s more likely attributable to ignorance of the *physiological* nature of addiction.
Addicts as a rule do not intend to become addicted. Every addict thinks he can “try it once or twice,” use occasionally & stop at will.
But addictive drugs literally & very quickly burn through the brain receptors which deliver pleasure responses, which in turn triggers a craving —a need— for more.
The brain is literally changed & the differences between before & after drug use show up on brain scans.
For instance, the brain’s of methamphetamine addicts resemble those of schizophrenics. Drug use *physically* alters the brain *structure* in ways that *cause* psychosis, beyond the addict’s willful control. When addiction takes hold, the addict no longer has any choice.
The brain *can* begin to rebuild itself & heal, but it takes many months, even years, & this requires outside intervention to prevent the addict’s access to the drugs, as well a to provide palliative antidotes.
