Under California state law, a person may not own a firearm if they are addicted to the use of any narcotic drug. If this person was arrested for possession in another state as a minor, went to rehab voluntarily, had their record sealed and the charges dismissed, is this enough to disqualify them from owning a firearm in California?
As a further question, people have been committed to a mental institution are disqualified from possessing firearms. If someone voluntarily entered a psychiatric ward for a single night in a different state, is this person considered to have been "committed" for the purposes of gun ownership?
