You shouldn't advertise posters that are bad for your health, otherwise people (especially children) will believe that this is right to do, although it is not.
Make illegal Vape adverts. They are everywhere, on buses, bus stops, taxis, shops, radio, road signs and more.
I am a 8 year old girl and I don't like seeing adverts of things that are bad for your health. Both of my grandmas died because of similar advertisements. When they were kids they saw Tobacco adverts and they started to believe that smoking was the right thing to do.
I don't want other people to get really sick and die because of this.
