BBC: Finn picks up a small, white, teabag-like pouch from a round, brightly coloured tin and places it between his upper lip and gum.
He and his mates use nicotine pouches - or snus - until they vomit, he tells me.
The strength of the nicotine - at 150mg a pouch - is enough, he says, to "immobilise" them, especially when they use two or three in one go.
"It's the burn at first," the 17-year-old explains. "You feel this burning sensation against your gums, and then you get the hit."
The hit, he says, is far stronger than any cigarette, and often he and his friends will lie down before they put the pouch in place, hidden under their lips.
Finn tells me how easy they are to use; they are so inconspicuous he even uses them at school.
"I've sat in class before and had one in my mouth that was so strong I was all over the place," he says. "I was sweating, salivating and struggling to concentrate." » | Ruth Clegg | Health and wellbeing reporter | Sunday, July 20, 2025
