People are breaking into cars because of social media trends. Remember Kia Challenge? https://en.wikipedia.org/wiki/Kia_Challenge

If heroin was free, nobody would be breaking into cars but there'd still be a problem.

I think we're missing the point debating addictiveness. meta very deliberately use patterns that result in compulsive usage - and at the scale they operate - cause a substantial amount of societal damage as a result.

Facebook is legal, like alcohol. People drive drunk and kill people. People drive while using facebook and kill people as well.

They're also not doing that to pay for tobacco. Come on. Heroin is justifiably illegal for good reason already; you're stretching the analogy past breaking point.
