you can not involve people in gambling, gambling is like a drug, do you want your children to be drug addicts ?
Gambling is not drug it can be addiction.Most of the things were are doing are addictions like using mobiles,chatting,taking selfies even eating foods have addiction so it depends on you use it the consequences will be.
That will better if we can avoid to convincing other people to enjoy gambling because if they become addicting, we will feel guilty especially if that person is our closest friends or family. We don't want to see they become addicting in gambling and that is why we don't have to tells other people to play gambling. If they are curious, they will find by themselves on how to play gambling and let them choose.
