What is something that can be considered as bad as smoking, but people still do it anyways?

Drinking alcohol.

I bring this up all the time, especially with Menthol cigarettes and flavored cigars being in the news recently because the FDA missed its own deadline for banning them. They specifically mention the flavor bans are because children like flavors, WTF, you gonna ban a coughdrop-tasting cigarette but still sell me Cotton Candy Vodka? How fucking hypocritical.
Beyond that, getting drunk has become a "fun" event when you're young or hanging out with friends. It is also so prevalent in movies and tv..
Agreed, especially young adults who get drawn to it thinking "drinking is cool" or something you do when you become an adult, that, has to stop.
Alcohol is way more ingrained into society though, we've been getting drunk for most of human history!

Giving your kids unrestricted access to TikTok/YouTube shorts

Man, youtube shorts just keeps going, forever.

Sugar

White sugar ESPECIALLY, just like the white bread, people, please go for ~~brown sugar~~ jaggery, wheat bread, the white ones are worse for health and very processed.
- Jaggery?

Doom-scrolling.

Life and the world isn't that bad. Like, in some parts it is, but people need to understand that you alone cannot exactly control everything on how they work. They're going to happen anyways. The media has, for decades, successfully ingrained people's minds and mentalities to believe everything must be bad by the minute and to always expect the worse.

But if you stop doom-scrolling for prolonged periods of time and realize this, things aren't as bad as projected.

Voting tory.

I'm going to sadly have to go with Porn here, I think it has unfortunately become a very normal part of the upcoming generations young life as they grow up, it sucks kids of today are being exposed to these things earlier than older generations were.

I think the bigger issue with porn addicts is how much time it can consume
- And how bastardized their perspective on social activities and being in public can get.
  Masturbate and consume porn too much, next thing you know, you're gazing at people's asses, crotches and breasts imagining all sorts of fantasies you'd like to do involving them.
  People expect sex within the first date. It could get worse from there.
- Absolutely, it can waste a lot of time
As an adult woman, porn is very beneficial to my sex life. So maybe the problem isn't porn so much as it is children's access to it.
- That is surely good for sure, I am not against that in any way, but there are some young adults who are locked with porn which really is fictional and taped, and they can often be bad at real relationships, especially if they get extremely addicted to porn, using porn to help with you sex life is great, but it shouldn't get to a point where it's doing you no good with real relationships. Hope I am making some sense here lol

Having sex with my ex-wife

Agreed. I never should’ve done that.

Alcohol is by far the most detrimental drug to both individuals and society and yet is the most socially accepted. Of course that last part is why it's the most detrimental.
