It depends on whether there has been a huge problem with gambling. Especially if it affects the peace and order of a certain society, because some people become violent when they run out of money or when they are buried in debt. It's either they steal or even kill out of desperation.
Frequent gambling won't be a problem as long as the people outside these vices are not gonna be affected. At the end of the day, it is always us who are responsible for what we have done.
