I quit smoking cigarettes and use extracted nicotine pouches like Dryft, Zyn, or Velo. They’re all flavored so I’m not sure if any are ok on Pesach. I know they also make tobacco pouches called Snus and there are a bunch of brands with both flavored and non flavored options. There’s also a few flavors of Nicorette lozenges that the OU and Star-K approve but they don’t have any info about them for Pesach. I’m okay with any option as I’ve tried the patches and they don’t really work for me as an option. I really don’t want to smoke cigarettes so if anybody knows of any kind of smokeless nicotine products for Pesach please let me know. Chag Sameach!
