Yes.  Both actual and constructive principles apply in drug possession cases.  Actual possession, obviously, means your child had the drugs on their person.  Constructive possession means that the following are true:   - Your child knew the drugs were there - Your child had the ability and intention to exercise control over the drugs   Finding drugs in a vehicle is a common example of constructive drug possession.  Even if it was not your child’s car, every person in the vehicle can be charged.
