Synthetic nicotine (non-tobacco) snus, which are usually just called nicotine pouches or “all-white”, are not banned for consumption in the rest of the EU. A lot of countries have bans on the sale of flavoured nicotine or menthol nicotine products due to menthol cigarettes which covers a lot of all-white nicotine pouches but you can still consume them.

Thanks, I didn’t know that was a thing.

Can someone explain to me what the justification would be for them being there? Is it typical that countries send some of their own law enforcement to the Olympics?
