I think that the OP left the building a long time ago. If you take a gander they have 1 post, this and this one alone from 2+ months ago.
That is the problem of pulling up an old thread many times. If you are trying to give guidance and the thread is months old it may have died because the poster left.
Do not me get wrong I think Jbow was giving sound advice about coming clean as soon as possible, just I think the OP has moved on, thus no assistance to them. This forum every year has at least one thread regarding being disenrolled due to marijuana use. It is important to know that each commissioning source (air Force, Army, Navy, Marines) all have a magic number that they will not waive after. AFROTC impo and the years here seem to be the most rigid. None of them that I know of will typically acknowledge the exact true number where you go from experimental to recreational. I have seen as low as 3 times for AFROTC.
~ Caveat it may not necessarily been the #3, but like Jbow stated they changed their numbers along the way. This one person originally said none on the scholarship. 1x on the DoDMERB. Came back after SFT and before contracting to a POC informed the CoC that it was actually 3 x. The CoC submitted them for a waiver, but AFROTC decided to dis-enroll them that semester. They never made it to the security clearance.
OBTW, yes, billyb, I think calling them a liar was a little over the top, but it is an internet forum and we cannot distinguish intonation. Sometimes it can be taken harsher than what was intended by the poster.
