Wait, you’re just repeating general empty statements. Why isn’t nicotine on its own good for you? A raised heart rate and BP for a period isn’t a bad thing. It’s an expected response from any stimulant.

I mean, sex and exercise also cause the same responses.

Sure, but people wouldn't downvote a comment suggesting having couple of cups of coffee per day to improve ADHD symptoms as hard, for example. And for me caffeine withdrawals symptoms have always been more difficult to overcome compared to nicotine.

For average tech worker HN user living a sedentary life-style, having stressful job in polluted city periodic usage of nicotine patches won't make it to their top list of health concerns IMO.

So much of the research and the general understanding is just conflated with cigarettes as the delivery type. They present a bunch of problems: the smoke and other chemicals makes it damaging in a lot of ways. People sometimes swap the terms “nicotine” and “cigarettes”. Cigarettes (and presumably vaping) have one of the highest and fastest nicotine deliveries — this is critical in creating the physical/chemical (dopamine) response that your brain and body use in addiction formation.

We can have two companies release the same code, but the ui/UX of the users interaction with it can make all the difference.
