Question

When I say “ how does social media marketing affect young people’s attitude towards the use of vaping”

Is it affect or effect?
Also is the use of people’s correct?

Answer 2

It’s affect. Effect or like side effects to drugs or something. For your second question I believe so, but I would say “A young person’s attitude”
