My nan smoked until she was 64 when my grandad died. She said it was too expensive for her then. She lived at home on her own until she was 96.
I would imagine many of these vapes are weed vapes. Better a whiff of custard air than a plumes of skunk smoke.
Mum and dad both smoked (Auld man had a lung out in his 50's and died relatively young) Me and my sister hated it and don't smoke. I think the level of ban is spot on now.
