Smoking and alcohol are primarily banned for children because they do A LOT more damage in children. For example, smoking before you are 16 or so has significant lifelong negative effects. If you smoke as an adult, and then stop, after a few years the effects are gone. Similar effects for alcohol. Similar effects for weed. Nobody knows for social media.
This is a teensy bit more complicated.
