Most of the addicted once had stability, but lost it because they would not give up their addiction(s).

The literature disagrees. The causes of addiction are complex, but are broadly based in factors that are reasonably considered 'instability' in the colloquial sense. These include things like adolescent abuse, SES, disengagement from 'conventional' society, mental illness, etc. There is a genetic component, but its contribution is relatively modest.

The trope of a well-functioning adult succumbing to the allure of drug abuse is a red herring.

'Could not' is probably a fairer and more accurate description of the disease of addiction.

I've never once in my life met an addicted person that preferred to stay addicted, have you?
