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!)

weed stays fine with age. maybe even gets better with age imo. i just recently was dry but then i remembered i had this shake from about a year ago in my closet. well i smoked it not expecting to get high at all and i got ripped as fuck. just from one waterfall hit too.

Yea, it keeps. Smoke that up when you get back bro

Thanks guys. Now I know I've got something good to come back to.:jointsmile:

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.

yeah with age its gets better like a fine wine, if you look at it, it should be more crystaly, atleast mine becomes that way, i lost 1/8 about a month ago, found it under my bed and it was pure crystaly goodness.

I would put it in a glass jar. I'm not saying there is holes in your plastic bag but the longer cannabinoids are exposed to air the more they degrade into non-psychoactive cannabinoids such as CBN and such with only mild effects. So just to be sure that it's not happening I'd just get some type of air-tight jar or bottle to keep it in rather than a plastic bag. I used to HATE what happened to my weed after a few weeks in the bag..

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.

if you can hermetically seal it and freeze it, it will last at least 6 years, maybe more

i saw it in a documentary last night, In Pot We Trust about medical marijuana. they gave a guy frozen sealed joints manufactured in 1996, and the doc was made in 2002

In Pot We Trust was really good. If anyone hasnt seen it... you should.

in a mason jar it'll last forever.

I keep them in Mason jars, in the fridge ... I don't freeze, as I suspect that might make the trichomes snap off, etc ... I just ordered a cheap vacuum food-sealer, that seems to be the hot trick these days .... just don't suck them down to the point of crushing the buds ... :smokin:

shit weed like wine it get better with age as long as it seeled

One month will be fine. If you want to keep it fresh though (better taste?) just put it in the freezer.
