Weed improves with age in my opinion. I've lost joints for weeks and when I found them, they got me blitzed. Much more so than when I first got the sac.
4twentE Reviewed by 4twentE 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
