Keepin' Weed fresh

Ok so I have maybe 2 grams rolled into three joints. I am goin on a cruise on march 11. I want to keep the weed stored so that it loses little or no potency. I have the weed in a can of mints rolled in a bag airtight.So will it be okay in there. Or should i store it somewhere else. And will it be be okay rooled or should I take it out of the paper .Thanks for any help.
-peace

Yeah your good just leave it in the bag in the mint tin.

well ive always heard that breaking or grinding weed decreases potency and to leave it in bud form. but if u alraedy rolled it up i guess its too late.
