Addiction is quite danger, but it is possible to stay within the limits. Around the World most of the suicides were taking place out of money problem and this is not just about gambling money.
Sometimes, an addicted person needs Isolation and attention that should be carefully examined either gambling or non-gambling, a gambler who is addicted may want to stay out of the limit but if they found their self in some situations they cannot control, they will definitely go back. Take, for instance, a gambler that has borrowed money from different people, especially loan sharks who always threaten their customers who don't return the money.
Gambling in some cases have helped them recover from financial struggle and in some cases it have made them go deep into financial problems. Until we don't have our control gambling is not the choice of entertainment for anyone.
Gambling is relative though, there are some gamblers who went from little financial struggle and still end up crying out because they encounter another financial struggle that is more that the first one.
