It's exactly the same with any vice (drinking or drugs etc.) where if there's a real, deep-lying addiction then they will often go to any means to fulfil their desires.
I have a friend who, while having a very powerful job as a barrister in London, became an awful alcoholic which ultimately destroyed their successful career and life.
We're talking about drinking heavily during their lunch while being in the pub all night, literally being an utter mess each and every evening - it was embarrassing.
Their firm were great and offered lots of help and support, including rehab and keeping her busy in the evenings (changing her hours) to keep her from temptation.
Her friends in London offered a lot of help as well by trying to keep her busy, move away from having social events where there was ale and lots of other stuff.
Anyway, she just began drinking in work instead before she was rotten in a court-case where the judge proceeding over the case tore her a new one - job gone.
In the end, she was caught drink driving, lost her license and intentionally took up a job in a local pub where she could drink wine out of a ribena bottle at 10am.
Husband left her and took the kids with him. It was only when she was set bloody straight by a fair few of us (we were oblivious up here) that she turned a corner.
I genuinely think that she would have ended up drinking her self to death or being leathered or killed in bar fight - an aggressive drunk - if not for tough talk.
Any addition must be related to a person's mental health as in those situations they are not making rational decisions.
