Really not that recommended on playing gambling when you are drunk or under the influence of alcohol on which we know that decision making and self awareness is really that not good on this time or moment on which you are really that prone into those all-in kind of behavior because you just dont really care on what are the things that could happen.You would really be just that only to be able to feel up those consequences on the time that you had just already make yourself recover or fine. Gambling problems do really start on someones own actions because if you do make yourself that too delusional towards your gambling dealing or involvement then this is where problems do commonly start and this is something that you should really be avoiding in the first place.
Those that have an addiction very rarely stop at one addiction and instead accumulate several during their lives, so someone that has some issues gambling could easily develop an alcohol problem, as gamblers that make big bets at a psychical casino often receive free drinks and other perks, so after a bad session they may begin to drink to forget everything that happened, a behavior that can easily lead them to abuse alcohol or other substances as well.
I agre with that, because addiction is a chain ⛓️ and is very easy for anyone who is addicted to gambling to freely slide into alcohol abuse also because the chain will easily connect and just as you said that alcohol is what is readily available in most casinos it easy to abuse such substance in those kind of places.
Just like those who drinks, the easily womanize and also smokes this things is a chain and it goes mostly together, breaking free from those addiction is one of a though decision that requires full attendance to things that matters as far as that change is concern.
