Have you ever heard of nicotine pouches? According to some people, they are set to overtake cigarettes in future. That may be a lofty claim, but nicotine pouches have done nothing but accelerate in popularity in 2020 and 2021. Moreover, there seem to be more and more brand popping up every day. My 2c is that this could be one of the biggest niches for affiliate marketing in future — and very few people have got on it yet.
