How Long Does Weed Stay Good?

There are many questions surrounding weed, and one of the most commonly asked questions is "how long does weed stay good". It's a valid question given the number of people who find a long-forgotten baggie in the bottom of an old bag and feel like they've stumbled across a hidden gift! The problem is that often, weed doesn't come with a printed sell-by date. You'll likely wonder how long the baggie will be fresh for, and how long does weed stay good? You'll worry you smoke it and it turns out that weed that isn't fresh isn't good to smoke. So many questions - and you're in the right place for answers!


In this article, we're going to cover all you need to know about how long weed lasts without going bad.

How long does weed stay good for?

The short answer to this question is that if your weed is in the ideal storage conditions, it can stay fresh for much longer that you expected. The right producers would have harvested, dried, cured and stored the weed for a bit before it's sold, and then it would have been in the dispensary for as long as it was there. Under these conditions, you'll find that your weed can last up to a year. The best stored buds can last up to two years, even, so it really depends on the way in which you store your weed. The issues that most weed smokers find is that the conditions aren't particularly ideal. They're not equipped with heat lamps and humidity controlled containers. They're not equipped with the right lighting for the weed to grow. Ideally, you want to try to ensure that your weed is consumed within the first six months of purchase. If you have the right equipment, you can push it a little further.

Okay, but how long does weed last?

Now you've read the short answer, let's take a look at the longer, slightly more scientific answer to this question. Before you can really understand how long it lasts, you need to know what will happen to your marijuana as it matures. All of the chemicals in your weed will break down over time. The potency changes as the terpenes start to slowly break down and this is where the weed loses its flavor. The scent changes, and eventually it becomes tasteless and doesn't have that same sharp taste as a fresh bud. You can tell pretty quickly whether your weed is good to keep using or not, and old weed isn't the best to smoke, so it's best to dispose of it if you notice it's tasting a little funky. Some of the research out there will tell you that after a year, weed loses around 16% of the THC in it and by three years, it's 34% of the THC that is lost.

How can I tell my weed is bad?

So, remember we talked about finding that baggie in an old backpack of yours? Here's how to tell whether that particular weed is any good:

  • If the storage was moist or humid, you'll find that there could be mold on your weed. It's not ideal at all to smoke moldy weed, so stay away from that.
  • If the weed has dried and crumbled, it's too old to use and needs to be taken to the trash.
  • Smell it. Is it smelling sharp and fresh? If not, it will be too old. The crisp scent of fresh weed is distinctive, and if you notice that the crispness is gone, it's time to get rid of the weed/
  • Any sponginess and weed that doesn't make any sound when you pull it apart could be moldy. It should also not break immediately into dust.


Each of these signs shows that your weed is bad and should not be smoked.


If you've checked your weed and it doesn't look good, you can - technically - still smoke it. It just might feel a little pointless given that it's old, possibly moldy and just not ideal! You won't get the high that you want and if the flower is moldy, you should just stay away from it and chalk it up to a loss. Any white mold, discolored spots or off-looks should be put solidly in the trash! Weed does go bad, and it's a better idea to know what to look for and avoid it.

How can I keep my weed fresher for longer?

Keeping your weed fresh all depends on what equipment you have. You can do your best to control the temperature and humidity of your weed by keeping it stored in a cool and dry - and don't forget dark - location. Weed thrives in the dark, not the light, and you can ensure that you keep yours potent and fresh with the right storage. Different products have different needs, and it's important to know the differences between them all. 


Flowers can be kept fresh with limited exposure to light and air. When you maintain the right humidity, you can keep the bud fresher for a lot longer than you thought! You can get storage containers for your weed, but if you prefer, you could also use a small glass Mason jar with the lid on very tightly, and keep it somewhere cool and dark.


Edibles are easy to keep fresh: just keep these in the packaging and store them in a dry place. They should be kept out of direct light at all times, and if they're in a cool location they won't melt.


No matter what you do, you need to keep your weed fresh and you should know where you put it all so that you don't have any moldy.
