[§663E-10] 
Defense.  It is a defense to any action brought pursuant to this
chapter that the person who possessed, distributed, or facilitated the
marketing or distribution of a dangerous or harmful drug did so under authority
of law as a practitioner, as an ultimate user of the drug pursuant to a lawful
prescription, or as a person otherwise authorized by law.



     A law enforcement officer
or agency, the State, or a person acting at the direction of a law enforcement
officer or agency or the State is not liable for participating in the illegal
