Do Carts Expire? What Happens if You Smoke an Expired Cart?

Ever wondered if your weed cart is still good? Weed carts, also known as cannabis cartridges, can expire. While they won’t necessarily make you sick, the quality of the oil degrades over time, affecting its potency and flavor. This article explores the factors impacting shelf life, signs of an expired cart, and proper storage techniques to maximize your enjoyment.


Do Weed Carts Expire

Yes, weed carts, also known as cannabis cartridges, can expire. While they technically don’t go “bad” in the sense that they’ll make you sick, the quality of the oil degrades over time. This means you won’t get the same potency or flavor as you would from a fresh cart.

Shelf Life of Weed Carts

The typical shelf life of a weed cart is around six months to a year if stored properly. Several factors can affect how long a cart stays good.

Storage Conditions

Storage conditions play a crucial role in maintaining the quality of cannabis vape cartridges. Heat is a significant factor, as high temperatures can accelerate the degradation of cannabinoids and terpenes. This not only reduces the potency but also affects the oil’s consistency, making it thicker and more prone to clogging. Light, particularly UV light, also has a detrimental effect, breaking down cannabinoids and terpenes, which leads to a decrease in potency and an alteration of the oil’s flavor. Air exposure is another critical concern, as it can cause oxidation, further degrading the oil’s quality. Therefore, airtight storage is essential to preserve the oil’s integrity. Lastly, excessive humidity can negatively impact the cartridge components and potentially introduce moisture into the oil, promoting microbial growth and spoiling the oil. Proper storage in a cool, dark, and dry place is vital to ensure the longevity and effectiveness of cannabis vape cartridges.

Type of Oil

The type of oil used in cannabis vape cartridges significantly affects their shelf life. Distillates, being more refined, often have a longer shelf life. This extended longevity is due to the removal of impurities and plant matter during the distillation process, resulting in a more stable and purified product. In contrast, live resin contains a higher concentration of terpenes and plant compounds, which contribute to its rich flavor and aromatic profile. However, these additional compounds can degrade faster than the more purified distillates, potentially leading to a shorter shelf life. Therefore, while live resin may offer a more robust sensory experience, distillates generally maintain their quality and potency for a longer period.

Quality of the Cartridge

The quality of the cartridge is essential for preserving the integrity of cannabis oil. Cartridges made from high-quality materials, such as ceramic and glass, are superior in maintaining the oil’s quality. These materials are inert and do not react with the oil, preventing any leaching of materials that could contaminate the product. Additionally, high-quality cartridges are more likely to provide an airtight seal, crucial for preventing oxidation and preserving the oil’s potency. The design of the cartridge also plays a significant role. Well-designed cartridges are engineered to prevent leaks and minimize air exposure, both of which help extend the oil’s shelf life. A cartridge that effectively protects the oil from environmental factors ensures a longer-lasting and more enjoyable vaping experience.

How to Tell If a Cart is Expired

  • Color Change: The oil has become darker, indicating oxidation and degradation of cannabinoids and terpenes.
  • Odor and Taste: The oil has a strange or off-putting odor and taste, a sign that the terpenes have broken down or the oil has become contaminated.
  • Performance: The cart clogs or leaks easily, which could indicate changes in the oil’s viscosity or issues with the cartridge materials.

Proper Storage Tips

To extend the life of your weed cart:

  • Cool, Dark Place: Store your carts in a cool, dark place, such as a drawer or a cupboard, away from direct sunlight and heat sources.
  • Original Packaging: Keep the cartridges in their original packaging (Child-resistant paper box, Child-resistant paper tube, Child-resistant mylar bags, pop-top bottle, glass tube) to protect them from light and air exposure.
  • Avoid Frequent Temperature Changes: Try to keep the storage environment stable, avoiding frequent changes in temperature.

By following these guidelines and paying attention to storage conditions, you can help ensure that your weed carts remain effective and enjoyable for as long as possible.

An expired THC or CBD cart may exhibit several visual cues that indicate it has gone bad. When assessing the appearance of the cart, it’s essential to compare it to how it looked when you initially purchased it.

  • Color and Transparency

Fresh weed oil typically has an amber or light yellow color and is transparent, allowing you to see through it clearly. If the color has changed significantly or if the oil has become cloudy, it could be a warning sign of expiration.

  • Consistency

High-quality vape oil maintains a uniform color throughout the cartridge. If you notice any separation or uneven coloring, it might indicate that the oil has degraded.

  • Darkening

As THC or CBD oil oxidizes, it may darken in color, shifting from golden to a dull brown or even black hue. This darkening is often a result of exposure to oxygen over time.

  • Clarity

Cloudiness in the oil can also be a sign of expiration. If the oil appears murky or hazy instead of clear, it’s best to discard the cartridge.


What Happens if You Smoke an Expired Cart



Using an expired vape cartridge typically won’t result in major health consequences, but it’s not recommended for several reasons.

  • Decreased Potency and Flavor: Over time, the cannabinoids and terpenes in the cannabis oil degrade, leading to a decrease in potency and flavor. Vaping an expired cart may result in a weaker high and an unpleasant taste.
  • Unpleasant Smell: Expired cannabis oil may develop an unpleasant smell due to the degradation of terpenes. This can further detract from the vaping experience.
  • Mold Growth: If the cartridge has been improperly stored or exposed to moisture, there’s a risk of mold growth. Mold growth is more likely in warm and humid environments. Inhaling mold spores can pose health risks and result in lung-related illnesses. Mold-infested cartridges should be discarded immediately.

While using an expired cart may not pose significant health risks, it’s generally not worth the compromised experience. It’s best to dispose of expired cartridges and invest in fresh ones to ensure a safe and enjoyable vaping experience.


Do THC Carts Expire

Yes, THC carts, just like regular weed carts, can expire. THC (Tetrahydrocannabinol) is the main psychoactive compound in cannabis, and the oil in these carts contains THC.

The expiration timeline can vary depending on factors like quality, storage, and the specific cart’s components, but generally THC carts have a shelf life of six months to two years. 


How Long Do Carts Expire

The exact expiration time for carts, specifically THC carts, can vary a bit, but they generally last anywhere from six months to a year if stored properly. When you store your carts in a cool, dark place (think cabinet or drawer), they can last up to a year, maybe even two. Heat, light, and air will break down the oil in the cart much faster, shortening its lifespan.


Do Dab Carts Expire

Yes, dab carts, like most cannabis oil cartridges, can expire.  While there isn’t always a set expiration date listed, the quality and potency of the oil will degrade over time.


Do Live Resin Carts Expire

Live resin carts, like other cannabis carts, technically don’t expire in the sense that they go bad. However, they do degrade over time, affecting both potency and flavor.

Live resin isn’t perishable like flowers, but prolonged storage can cause the cannabinoids and terpenes to break down. This can lead to a loss of potency (around 25% after a year) and a change in flavor profile.

Over time, THC in live resin can degrade into CBN (cannabinol). CBN is less potent than THC and tends to produce more relaxing, sedative effects. This transformation is gradual and influenced by storage conditions.

Terpenes, which contribute to the flavor and aroma of live resin, are volatile and can evaporate or break down over time. This results in a less flavorful and aromatic product.

The good news is that using a degraded live resin cart won’t cause any health problems. It just means the effects might be weaker and the taste less desirable.


Do Delta 8 Carts Expire

While proper care and storage can extend their potency for up to a year, Delta-8 vape cartridges don’t have a single, definitive shelf life. The exact lifespan depends on the specific cannabinoids and terpenes in the oil, as well as the cartridge’s quality. Generally, most carts are considered past their prime after around 1.5 years. Extended storage can lead to a gradual breakdown of cannabinoids and terpenes, resulting in a decrease in potency and a shift in flavor profile.


Do Disposable Carts Expire

Disposable vapes, including those containing Delta-8 THC,  behave similarly to refillable cartridges when it comes to expiration. The e-juice inside the disposable cartridge can degrade over time, especially if exposed to heat, light, or air. The effects might be weaker than when the cart was new. The flavor of the e-juice might become unpleasant. With proper storage (cool, dark place), a disposable vape cartridge can last anywhere from one to two years.


Do Wax Carts Expire

Yes, wax carts, just like most other cannabis oil cartridges, can expire.  While they might not have a set expiration date printed on them, the quality and potency of the wax concentrate will degrade over time.


How to Stop a Cart from Expiring



While it’s impossible to completely prevent a weed cart from expiring, there are effective ways to delay the process. Proper storage is paramount in this regard.

It’s essential to emphasize the importance of storing your cart correctly when not in use. Leaving it attached to the battery poses potential risks, as batteries can malfunction and inadvertently heat up, leading to leaks or even fires. To avoid these dangers, it’s best to detach the cart from the battery and store them separately when not in use.

Additionally, maintaining the right temperature is crucial. THC molecules degrade more rapidly in temperatures exceeding 70°F (21°C). However, extreme cold, such as storing the cart in a freezer, can lead to issues like cart cracking or oil crystallization. Therefore, it’s advisable to keep the cart at room temperature or slightly cooler to prevent deterioration.

Direct sunlight should also be avoided, as it can accelerate the degradation process. Opt for cool, dark, and dry storage spaces, such as cool drawers or enclosed areas, to preserve the freshness of the cart. In temperate climates, storing the cart in a dark corner of the basement can be particularly effective.

Lastly, using the cart promptly can help mitigate expiration risks. While there’s no need to rush through it, avoid purchasing carts if you don’t plan to use them in the near future. By following these practices, you can prolong the lifespan of your weed cart and enjoy its benefits for longer.

Can I Hit an Expired Cart

While expired cannabis cartridges won’t be as effective, they typically don’t contain harmful compounds. Expired carts likely won’t cause health problems. The main concern is the decline in quality. The cannabinoids (THC, CBD, etc.) degrade over time, making the effects weaker. The flavor and aroma can become unpleasant due to terpene degradation. In some cases, the oil might thicken or clog, making it difficult to use. So, while you can “hit” an expired cart, it likely won’t be an enjoyable experience. It’s better to stick to fresh carts for optimal potency and flavor.


Is a Cart Still Good After 2 Years

You can potentially use a 2-year-old cart, but expect a significantly reduced experience. Cannabinoids and terpenes break down over time, especially without proper storage (cool, dark, airtight). The effects will likely be much weaker than when the cart was new. The terpenes, which contribute to flavor and aroma, degrade, making the cart taste harsh. For the best experience, it’s best to avoid carts that are 2 years old. Fresh carts offer optimal potency, flavor, and overall enjoyment.


Final Words

By understanding how storage conditions, oil type, and cartridge quality affect shelf life, you can extend the lifespan of your weed carts. Look out for signs of degradation like color change, odd taste, or performance issues. Following proper storage practices, such as keeping them cool, dark, and in their original packaging, will ensure you get the most out of your weed carts.



When Should You Throw Away Your Cart?
Generally, it’s best to discard cartridges after two years from the manufacturing date to ensure optimal performance.

Should Carts Be Kept Cold?
It’s generally recommended to store vape cartridges in moderately cool environments with consistent temperatures. Extreme temperatures, whether too hot or too cold, can lead to issues such as leakage or difficulty vaporizing the liquid inside the cartridge. Therefore, it’s best to avoid exposing cartridges to freezing temperatures, as it can affect their usability.

Can I Still Smoke a Cracked Cart?
Using a cracked vape cartridge is strongly discouraged for several reasons. Firstly, it poses potential health risks as cracks can compromise the cartridge’s integrity, allowing harmful substances to mix with the vapor. Moreover, leaks resulting from cracks not only waste oil but may also damage the vaping device. Additionally, cracks can lead to performance issues such as uneven vapor production or difficulty in drawing vapor.

Is It Bad to Hit an Expired Cart?
While hitting an expired cart might not pose immediate health risks, there’s a chance that the degraded components could produce byproducts that are less than ideal for inhalation. Additionally, if mold has grown in the cartridge, inhaling mold spores could lead to respiratory issues.
What’s more, vaping an expired cartridge may result in a subpar experience overall. The diminished potency, flavor, and potential presence of unpleasant odors or tastes can make for a less enjoyable vaping session.

Is It Bad to Smoke a Brown Cart?
If a vape cartridge has only turned slightly brown, it may still be usable, although the flavor and potency might be diminished compared to when it was fresh. However, if the oil has become thick or dark brown, it’s a sign that it has significantly degraded, and it’s best to discard it.

Is It Bad if My Cart Is Dark?
If your vape cartridge has turned dark, it’s generally not a good sign. While it might not necessarily be “bad” in the sense of causing immediate harm, it indicates that the cannabinoids and terpenes in the oil have undergone significant degradation. This degradation can result in a loss of potency and flavor.
