Yeah, you are right with your opinion because it depend on our mind how seriously we are taking this, I also think if we don't have addiction of gambling than gambling is very attractive and fun to get relaxed after having a hard job, if we are greedy and want to get rich than it can be sickness.
gambling is not considered as a sickness because is different, gambling is just an activity of what we do, and addicting is just a habit, like addicting in drugs, but again, addicting in gambling and addicting in drugs is different. so gambling is just playing games with money involve and its not a sickness
But if you get addicted to gambling, you will lose control of yourself. That is what is bad with it and what it makes like a sickness. The negative effects of gambling addiction is too much. Maybe gambling is okay if done sparingly. But too much of it is bad and can be considered a sickness.
It is indeed a bad impact of gambling and I think all the people who always do the gambling will certainly get it. Because of the nature of addiction in the gambling will certainly be obtained by those who conduct gambling more than 3 x. So, do best when we do gambling, do not let emotion and greed overwhelms our thoughts
