It appears there are some conflicting studies, like with everything.

My best interpretation is that nicotine itself probably isn't the-worst-thing-ever if it was restricted to occasional usage, like having a beer on the weekend.

It's probably not a good idea to make a habit of though like with coffee.

There's a theory floating around that it may help with long-Covid symptoms, but there's not a lot of evidence. This may be in part due to the general opposition towards tobacco as extremely unhealthy.

I only heard of this because a neighbor says using nicotine gum restored her sense of smell.

Again, anecdotally I had a relative, very heavy smoker, who got Delta and had very mild symptoms. She's 80 and in pretty poor health. Others younger in the same household had it much worse.
