Peer pressure is real among kids aged 8-22 (yes, that's a huge range but that's what is). You can stop your kids all you want, but then they will find ways to experience what you have deprived them of, and that will be catastrophic for their development and relationships in general. I'd like some child growth specialist to chime in, but I believe this dynamic won't be good as parents are a safe haven for kids and if kids think parents are not letting them have something that all the other kids have, it might affect them longterm.
