Does pot (Marijuana) get old?

Use a heavy freezer type plastic bag as per "I Can Answer..", vacuuming the air out with your mouth before sealing the last little bit of the opening. Then follow "Fisherwoman"s advice and put it in a canning type jar, or any jar with a good rubber seal in the lid. Store in a cool, dark place, and it should be in good shape when you're ready for it. To help keep it fresh, try to open the jar & bag as little as possible. If you're still smoking, take out what you need for the immediate future and seal up the rest.
