Make sure you keep it in an air tight bag, or wrap it in cling film, then in a bag, in a cool dry place. It will be fine, don't even worry about it.
WeedyBoyWonder Reviewed by WeedyBoyWonder on . How long does weed keep? So I got a bag of weed a few weeks ago, and I have a few grammes left, but I'm off on holiday and I want to save it up for when I get back in a month or so. How long does weed keep? I've got it in a little sealed plastic bag in a cool dark dry place. Will it lose its potency? And if I were to get some hash in the future, how long would that keep? (And yeah, I know I should probably just have it now, but hey, I'll need something for those post holiday blues!) Rating: 5
