Natural selection for stupid people?

[Another Dude]

Do you think natural selection will become a thing for stupid people? This is an honest question. My fellow teenagers are selfie-taking, drug-doing, party-going idiots. Don't get me wrong, I'm not some stuck up kid who think he's smarter than people. I'm of average intelligence (which is sad that I can actually look down on these people).

With their compulsive use of drugs and the need to take selfies (like taking an imagine of yourself while your grandma is dying, thanks Facebook) will the things they do eventually kill them?

I'm thinking about alcohol and drugs, mostly. But social media addicts can easily become the people living in their parents basement until they get kicked out, live on the streets, and starve. So. While a strange question, I'm doing this for my own thinking.
