Gambling is dangerous, and I would advise anyone close to me to stay far from it because it's results are not friendly as pressumed. Gambling have dealt with me, I've complain and also worked on myself on becoming the better version. Gambling and recording streak losses have also become one of the discouraging records for me, though I never stop but keep placing wagering on games for better results. Addiction is the top challenge everyone faces this season but we just have to apply disciplinary measures if we care to survive for long in the system.
It’s ironic because the one that saying this words is being paid by a casino for posting such comment.
Gambling in general is not dangerous since it doesn’t force you to play or requires you to deposit huge amount to play. The gambler himself is the one that makes it dangerous due to their greedy. Greediness should be the one to blame since the casino itself doesn’t force to become greedy.
I believe you should warn your friends to not play if they can’t handle greediness because that’s the thing that makes people lose money and not the casino that just offer games.
Generally, something that can harm you or anyone in any way can be labeled as dangerous even if the harm is triggered by your actions or the actions of someone else, but since it is harming you for your involvement, you can say that it's dangerous because anything can happen at any given time if there is a trigger. Take a gun as an example of this, a gun is generally used for protection from the bad which means that it's not something bad but if you put the trigger while it's pointed towards you or someone else, that's dangerous, for sure.
Therefore, even though you are right that a person who gambles irresponsibly is taking the risk and danger themselves because they are allowing gambling to tear their life apart, I believe gambling itself does have a lot of risks which is the reason why we can call it something dangerous or maybe a dangerous addiction, to be more precise.
