We haven't had much trouble with DS17 up until now which is why this comes as such a surprise. DS17 is doing great academically and is studying 4 difficult a levels.
However we recently discovered he is a regular user of nicotine pouches. I was furious when I found out and spoke to him very harshly however I'm looking for some advice before I proceed any further. AIBU to be furious about his nicotine pouch usage? What action can and should I take against him other than explaining the HUGE risks which I'm sure he's already well aware of.
