Yes, I've noticed something simila, although way I phrase it is I noticed among high marijauna users from teens to twenties was what is a sense of delayed maturity. This overlaps with the attributes you described but it also felt like they weren't able to accept the increasing responsibility to themselves and others that comes with growth out of adolesence. I accept this is just one lived experience and there are other possible confounding factors, but I've definiutely noticed it.
