Facts:
Marijuana was found in my Client's book bag as he was attempting to enter his school.
Client performed 25 hours of community service prior to court and the Commonwealth's Attorney agreed to nolle pros (dismiss) the charge against him.
Note: While a lot of the facts of this case are omitted intentionally, possession of a controlled substance can only be established if you are aware that the substance is "present," and you are aware of what the substance "is."
So... actual possession = presence + knowledge
