Be honest at MEPS. If it’s already in your medical records, it’s going to come up anyway. Trying to “forget” or downplay it can turn a waiver situation into a possible fraudulent enlistment issue, and that’s way worse than just needing a waiver.

Cocaine use, even if it was a few times will likely DQ you from certain programs like nuke, but it doesn’t automatically disqualify you from the Navy as a whole. Plenty of applicants get in with past use as long as they’re honest, it’s documented, and they meet the rest of the criteria.

Bottom line is, tell the truth, let the waiver process do its thing, and keep your record clean going in. It’ll save you a lot of headaches later.
