I smoked ~4 years light/social post high school. Dipped Copenhagen Pouches for ~10 years. I've tried to quite with some success with the longest streak being 2 years. It is incredibly hard and all in the mind.
I found ZYN pouches last year and they have replaced my needs. It "... is a tobacco leaf-free nicotine product. The nicotine salt used in ZYN is derived from tobacco leaves, but once the salt is extracted, no part of the leaf remains." The rest of it is says its food-grade.
Obviously the best would be not to use anything. But would anyone happen to know if this is still leaving a lot of risk exposure? My thought is its probably about as safe as I'll ever find, and really just giving me the nicotine I've become used to without the bad stuff, as nicotine itself is not what causes problems. But if anyone has more informed opinions that would be helpful.
