Past drug usage -- Gunners Mate

[Mavyboy]

Hello again all! I have another similar question to all of the other threads I posted..

Okay so I can't enlist as a GM because I had a possession of drug paraphernalia ticket wavered, and I admitted to using spice on one occasion. My recruiter was looking up what jobs I qualify for to show me what else I could have besides PACT SN, I told him the only rate I would sign for other then PACT was GM and he proceeded to show me the list of all the jobs within the navy and he showed me GM, and in a small box next to the requirements it stated "no history of drug abuse"

Now once I am in the navy and do my time as a PACT SN will I be able to cross rate into GM? Given that I have a ticket (waived) for possession of paraphernalia and I admitted to using it once?
Unfortunately I had originally thought that yeah you can, which is why I didn't ask my recruiter.

Sorry for beating this horse so much I just want to know what I'm getting myself into haha! Thank you everybody
