The Supreme Court of Arizona has ruled that persons who are prescribed drugs owe a duty of care, making them potentially liable for negligence, when they improperly give their drugs to others.
The defendant shared his prescribed drug (oxycodone) with others at a party. One of the women he shared the drugs with gave them to the plaintiff’s decedent, who died that night from the combined toxicity of alcohol and oxcyodone. The plaintiff (decedent’s mother) sued, and defendant denied that he owed a duty to the decedent.
The Court held that because Arizona had statutes prohibiting the sharing of prescription drugs a duty existed. The Court said that "[b]ecause [the decedent] is within the class of persons to be protected by the statute and the harm that occurred here is the risk that the statute sought to protect against, these statutes create a tort duty."
