ART. 112a. WRONGFUL USE, POSSESSION, ETC., OF CONTROLLED SUBSTANCES
(a) Any person subject to this chapter who wrongfully uses, possesses, manufactures, distributes, imports into the customs territory of the United States, exports form the United States, or introduces into an installation, vessel, vehicle, or aircraft used by or under the control of the armed forces a substance described in subsection (b) shall be punished as a court-martial may direct.
(b) The substances refereed to in subsection (a) are the following:
(1) opium, heroin, cocaine, amphetamine, lysergic acid diethylamide, methamephetamine, penecyclidine, barbituric acid, and marijuana, and any compound or derivative of any such substance.
(2) Any substance not specified in clause (1) that is listed on a scheduile of controlled substances prescribed by the President for the purposes of this article.
(3) Any other substance not specified in clause (1) or contained on a list prescribed by the President under clause (2) that is listed in Schedules I through V of section 202 of the Controlled Substances Act (21 U.S.C. 812).
Not withstanding a Medical MJ script, possession is still a federal crime. That makes it wrongful possession. If, of course, he had the slightest discernible amount.
ART. 134. GENERAL ARTICLE
Though not specifically mentioned in this chapter, all disorders and neglects to the prejudice of good order and discipline in the armed forces, all conduct of a nature to bring discredit upon the armed forces, and crimes and offenses not capital, of which persons subject to this chapter may be guilty, shall be taken cognizance of by a general, special or summary court-martial, according to the nature and degree of the offense, and shall be punished at the discretion of that court.
Being in the news about being there brings discredit, etc.
