Most nicotine users today? Everyone’s using the pure nicotine pouches like zyn and such. I didn’t really find it enjoyable at all

A lot of people consume nicotine. It has been isolated and used in products for a long time. There's no clear link to cancer, but it could impact cardiovascular health (like all stimulants seem to).

Some research indicates that nicotine can influence how existing cancer behaves and spreads, so that's worth considering.
