Before you even think about buying your first batch of weed, you need to know how long you can keep it for. So, does weed go old? And when it does, is it still “okay” to use? Above all, how do you know if it’s already “old”? Well, you’ve come to the right place.

Today, we will break down the four weed facts you need to know regarding how and why weed goes old or “bad.” Of course, we’re going to equip you with ways to avoid having a bad time with your purchase. Let’s get started:

  1. Weed can go old or “bad,” depending on your definition.

Surprisingly, answering the question of “does weed go old?” demands subjective interpretation. Among all the weed facts in this list, this is the question that people get wrong most of the time.

If you define “old” and “bad” as rotting like milk, meat, or cheese. Then, no, your weed will not go through that extent. See, weed isn’t a dairy product; it won’t rot the same way most food products do.

Weed, or cannabis products in general, go old by losing their quality. Meaning they can’t be as potent and fresh as they did when you first got them. Their texture is also going to change a lot. It’s going to be very brittle and dry. Furthermore, the smell is going to change. We’ll get more on this below.

But if you think weed is going to give you an upset stomach or poison you, it’s not. Think of it like dried herbs hanging around your kitchen shelf. If you haven’t used your garlic powder for ten years, it’s going to be hard and extremely dry. Weed works like that.

Yes and no. Many weed facts debate its effect on the human body. But, we can learn that the mold and mildew from old weed can lead to side effects that are harmful to the body. This can lead to sinus pain and congestion. And if you’re likely to be allergic to such conditions, it can trigger various reactions inside your body.

The time where old weed isn’t harmful is when your body doesn’t react. Sure, dry and brittle weed tastes and feels terrible. You’re most likely to cough a lot. But if you’re not allergic or sensitive to mold and mildew, you won’t experience much discomfort.

We can’t promise the same results or reactions for everyone. However, we strongly discourage consuming old weed. Aside from safety and health purposes, you wouldn’t want to experience less from what you purchased. Also, moldy weed isn’t really the best thing to smoke out there (it’s pretty gross too!)

  1. You control weed’s “expiry date.”

It’s more than knowing how does weed goes old. The critical question is how or what you can do about cannabis products’ aging process. If you want more details on how to store weed, we have an in-depth tutorial in this article.

Dried cannabis can be stored without any problems for 6 months to 1 year after being purchased. Over this time, you shouldn’t be able to feel any loss in its aroma, potency, and overall quality.

Based on a study regarding this subject, it’s found that weed loses around 16 percent of TCH content after a year. For more information, refer to the table below:

Duration: Percentage of THC Loss:
One (1) Year 16 percent
Two (2) Years 26 percent
Three (3) Years 34 percent
Four (4) years 41 percent

Unfortunately, weed is not going to age “like fine wine.” THC or Tetrahydrocannabinol is the substance responsible for the psychoactive effects of consuming weed. It’s basically the reason why other cannabis products like distillates, capsules, or oils can make you feel “high.”

If weed is old enough to lose most of its THC content, the potency will be affected. “Potency” refers to how strong the product is once consumed. So if the potency decreases because the THC content is reduced, you can expect that the effects of weed won’t be as good.

Other users who insisted on consuming weed that’s way past its date report that the experience was awful. They described that the taste was unpleasantly harsh without the good, cloudy sensation. And that the smell changed a lot after not storing it correctly or consuming it again after many years.

The farthest you can keep your cannabis products is two years. May it be buds, oils, or distillates, two years is the highest expectancy. The common rule in weed states that anything after two years will most likely lose its quality and potency. You can’t stop weed from losing going through its chemical change after time.

However, you can lengthen its quality with proper storage. Instead of six months, you can keep it fresh for two years.

  1. Weed changes when it gets old.

“Good” or fresh weed that’s recently been purchased from a dispensary has main cannabinoids. These are CBD, THC, and CBC. These are great for your experience since they are responsible for the taste, feeling, and aroma. But, when your weed is exposed to ultraviolet light (from the sun) or when they’re stored incorrectly for a long time, your weed will change.

How? Instead of THC, it’s going to be CBN (and you wouldn’t want this.) CBN is a cannabinoid that’s basically THC’s traces when it’s aged. This isn’t a good thing because CBN is a lot less potent, and most of the time, they’re pretty underwhelming if you’re up for a good time. So what should you do?

To avoid this whole “CBD agenda,” you want to keep your cannabis products somewhere dark. Don’t underestimate this process because even if weed is exposed to sunlight for only a matter of seconds, a lot can change composition-wise.

Sunlight and moisture are your enemies. The harsh rays from the sun are going to dry out your weed. They’re going to end up very brittle. Meanwhile, moisture is going to welcome mold and mildews from entering your weed. Moisture can be induced by air that’s caused by poorly storing your cannabis products.

Weed is similar to human skin. When our skin is excessively exposed to the sun and smoke through pollution, it will age quickly. You wouldn’t want to prepone these things from happening. Weed doesn’t have sunscreen as we do. But, storing it well is the answer to all of these problems.

  1. You’ll know when your weed goes old.

Does weed go old? Yes. Will you know when that time arrives? Yes. You won’t be clueless because the signs are going to be noticeable.

The first thing to observe is the smell. Cannabis products have a very distinct aroma when it’s still in its prime. So if you’re starting to notice that it’s a bit harsher than usual, it’s most likely old. Take note that some weed aromas are intense. But, the kind of scent old weed gives off is this “unpleasantly harsh scent that hurts your nose” and not the rich and robust weed smell people like.

The next thing to notice is the appearance and texture. If it looks spongy, it’s old. And if you hold it and it starts to crumble even if you didn’t “push” or intentionally break it, it’s way past its prime. Anything extreme, like too dry or too moist, are also signs of aging.

Obviously, if you see molds in your weed, it’s a given that it’s not in the best condition.does weed go old, cannabis products, weed facts


Yes. If you look at your weed closely and see white, powder-like spots that are “fuzzy,” bad news. Your weed has molds on them. As gross as it may sound, molds also give off a smell. Again, it’s a powerful, hay-like aroma. And if you insist on consuming it, you’ll notice that the taste is a major downgrade to fresh ones.

We strongly discourage consuming moldy weed. Aside from experience, the dangers it can do for your health are unpredictable. We want to avoid that as much as possible.

The Summary: Does Weed Go Old?

Does weed go old? Yes, it does. We can tell this from its texture, potency, and changes in sensation. If left poorly stored, it can go as far as growing mold and mildews that bring health issues and downgrade one’s experience in weed consumption. We can avoid these and prolong the weed’s quality by properly storing it. And, of course, by buying the weed from a trustworthy dispensary that values quality.
