If you are not a heavy user, edible marijuana typically leaves your system within 1-to-4 weeks. The less BMI, the faster it leaves your system.
This is not a guarantee you won't pop positive, though.
Best advice is don't do it again. If you were under the influence of alcohol, reconsider your drinking habits too.
@Day-Tripper , I have to agree with you on this one, keeping the following facts in mind:
- OP is not contracted.
- OP is expressing regret
- OP did not specify circumstances of consumption
- OP did not specify length of progression in their ROTC program
- AF has changed their pre-service marijuana consumption policy (no clue which branch ROTC OP is in)
Folks, when addressing something like this, please keep in mind DoD pre-service drug policy has changed a lot over the past year or so, and that non-contracted (i.e. not "enlisted" into the USAR, USNR, or USAFR, which means not subject to UCMJ or any other military regulation) ROTC cadets don't necessarily follow the same rules as military members. If they haven't been sworn in, they are just college students participating in an extra-curricular program. Different set of rules.
So, unless OP has somehow been inducted into ROTC without being contracted, I am unsure why they are subject to drug testing, and would warn
against self-reporting (and question taking any drug tests) until/if asked when they are eventually contracted.
Do not lie if asked, but similarly do not volunteer errors you have made unless you are obligated (morally or legally) to do so.
