Definition - What does Stash Jar mean?
In cannabis culture, a stash jar is any container, vessel, or receptacle designed or reconfigured for the purpose of storing one’s supply of marijuana, cannabis edibles, or other related consumables for recreational or medicinal purposes.
Stash jars are either used to conceal said possession from possible discovery, or just to store it in a manner that will prolong its freshness or usability.
Ideal stash jars are sealed in such a manner to eliminate or reduce the amount of oxygen, heat, light, and moisture that can come in contact with the stored product(s). They may be stored in a cool environment such as a refrigerator, but a freezer is not advised.
