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.
It’s not my thing, I do have a small basket of stocks I call gambling (they break even) and husband spends $2 a week on a lottery ticket.
Other than those I abstain, it’s not really fun to me.
