Amends TCA Title 39; Title 53 and Title 63.

This bill enacts "Brittany's Law," which provides that a person commits a Class B misdemeanor who knowingly fails to seek medical assistance for an individual who the person knows or reasonably should know is experiencing a drug overdose. A Class B misdemeanor is punishable by a term of imprisonment not greater than six months or a fine not greater than $500, or both. This bill provides that a person does not violate the above provision if the person refrained from seeking medical assistance because the person reasonably believed that medical assistance had been previously summoned by another. This bill allows the sentencing court to order the defendant to complete a clinical substance abuse assessment and participate in a substance abuse treatment program licensed or certified by the department of mental health and substance abuse services, including aftercare recommended by the treatment program.
