Could be in any context. I do it a little on UFC fights but that’s a relatively low amount and I can afford I to lose any time I do. It seems like it’s becoming a really wide spread problem though, at least in the US. At the same time I don’t see why it should be illegal. Granted I also don’t think any drug should be illegal.
Gambling destroys lives. Making gambling illegal may be controversial, but I can’t see any reason to allow gambling ads.
If you want to gamble, then it’s your own life to ruin. If you advertise gambling, then you are ruining other people’s lives.
Ban gambling ads.
