I think so. Adults can get addicted very easily. It’s compounded by the fact that we don’t generally think of the dopamine hits provided by social media as something that can be addictive, so we are not very careful.
But similarly as with alcohol and marijuana, the effects on a developing brain seem much more profound.
(Caveat: I am not a specialist, but the limited reading I did from the literature and my limited experience point to that direction.)
