I think its more of an analogy which is by definition an imperfect comparison. Its a serious disease or disorder of the brain. Many people do not get addicted even though they use or drink. I don't think people choose to get addicted. You can also compare it diabetes or heart disease.
Addiction has stigma. So people lie to hide it. (I guess its like leprosy before antibiotics). Lepers were social outcasts. Addiction also drives the need for money (esp. illegal substances which are expensive). I think there is a difference between understanding that lying etc. are symptoms and overlooking. I think addicts should be held accountable for their actions. But the prison system is not the answer for a non-violent addict.
