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 like alcohol. Kids should not use it. Most adults are able to use it in moderation and are fine. It’s stupid but they are free to spend their money however they like. Some people can’t handle it.
It should be regulated by limiting access to it, limiting advertising and protecting people that can’t handle it.
