Yes I think gambling is wrong, its almost the same as drugs, people need it in their day to be happy.
A lot of people are addicted these days and cannot act normally anymore in the normal world, they are losing everything.
Drugs cannot be compared to gambling, drugs is the worst vice that we could think of, but gambling, if you tried it, the more you have knowledge about the game, the more you'll have control on your moves, while drugs is the reverse of it...though you will lose money on both, in drugs you will lose your brain aside from your money..
