But the third time substance abuse impacts someone's professional life is clinically considered a strong positive sign of addiction, and exploring clinical treatment may be beneficial to him.

This isnt all conjecture. Getting suspended from work due to substance abuse is an objective indicator of addiction, as as is legal trouble due to substance abuse. People who arent addicts usually dont continue to use after being suspended from work twice and getting a DWI. That is addict behavior, flat out.

I actually feel bad for the guy and hope he has people in his life who actually care about him as a person.
