Will having tested positive for marijuana affect my contract?

DoD Directive (DoDD) 1010.1 - establishes the DoD drug testing program.
AR 635-200 Chapter 14 - section 3, 14-12 c (2) - separation for drug use by regulation could very well be paraphrased "we don't want you"
Separation for Misconduct
Section III
Acts or Patterns of Misconduct

14-12. Conditions that subject soldiers to discharge

Soldiers are subject to action per this section for the following:

a. Minor disciplinary infractions. A pattern of misconduct consisting solely of minor military disciplinary infractions. Except as provided in paragraph 1-13c, if separation of a soldier in entry-level status is warranted solely by reason of minor disciplinary infractions, the action will be processed under chapter 11.

b. A pattern of misconduct. A pattern of misconduct consisting of one of the following:

(1) Discreditable involvement with civil or military authorities.

(2) Discreditable conduct and conduct prejudicial to good order and discipline including conduct violating the accepted standards of personal conduct found in the UCMJ, Army regulations, the civil law, and time-honored customs and traditions of the Army.

c. Commission of a serious offense. Commission of a serious military or civil offense, if the specific circumstances of the offense warrant separation and a punitive discharge is, or would be, authorized for the same or a closely related offense under the MCM.

(1) An absentee returned to military control from a status of absent without leave or desertion may be separated for commission of a serious offense. (See para 1-43 for civil offenses under investigation by foreign authorities.)

(2) Abuse of illegal drugs is serious misconduct.

Be careful.. in 3-4 years that comment will be considered racist.

PFC James Smith - Interesting because if you google it, dictionary companies are changing the definitions of words for political purposes.. They just recently wrote racist to a way that completely changes the meaning.. They recently even redefined woman because it was said to be sexist.. total clown shoes.

Yes Sir! And you're spot on with that assessment and as a leader myself, I have heard every excuse in the book why a Joe tested positive for THC.

He's not smoking a "bowl". It's called a "blunt"...for future reference.

PO1 Eric Booker - I still struggle with being up to date on the lingo of the youth.

Come on, Tom - you gotta be hep to the jive and be able to groove on what the cats are layin' down on the streets, if you catch my vibe. ;)

MCPO (Join to see) - I was able to understand what you said since that is old school street talk........but today's youth....yea, I can barely understand them.
