Is it understandable a teenage boy would smoke weed if his dad dumped him?

If a boy is thirteen years old and his father lives one hundred miles away and has called him about four times, never visits him, and is raising a different son from a different woman would you think it’s reasonable for the boy to begin smoking pot at thirteen to deal with the anguish? Or would you think the boy is just a loser, maladjusted and headed for disaster.
Please don’t suggest what I should do for him or ask if I know him. I’m just interested in how you would view such a child.
