Article is pretty weak honestly. Claims these products are heavily marketed but I just don't see any advertising for them at all really. Where do these things even get advertised?

Facts are people like a nicotine buzz. It goes well with work and the lack of spit or any smell means it is compatible with basically every job, whereas with a vape you'd have to find a moment to inconspicuously hit it and zero the hit if you can't blow it out openly. You can bring a pack of this stuff anywhere you can't smoke or vape normally. It goes well with drinking. It goes well with smoking weed. The biggest advertisement is probably someone next to you throwing back a pouch and asking if you want one. The second biggest advertisement is the pouch you see spat out in the urinal. They really don't have to do much. It sells itself on its own merits. People have been fond of stimulants for thousands of years now. That isn't going to change anytime soon.
