How Much THC Is In A Joint?

Smoking joints remains a timeless and popular way to smoke weed thanks to their convenient size, portability, cost-effectiveness, and share factor. But how much THC is in a joint? Does the THC content vary when you’re talking about concentrate or kief-infused joints? Here’s everything you need to know.

How much THC is in a joint?

The average THC content in a joint is approximately 15-20%. However, your joint may be more or less potent based on the potency of the weed itself. For example, if you’re smoking a 12% strain, you might have around 12% THC in your joint. On the other hand, if your joint checks in at 28% THC, it’ll be a 28% joint.

What factors determine how much THC you’ll find in a joint?

There are a few different factors at play that may affect the potency of your joint.

Starting Material:

The starting material used to make your joint can have a significant impact on its potency. Different strains of cannabis have varying levels of THC, CBD, and other cannabinoids, which can affect the overall strength and effects of your joint.


Some people like to add additional ingredients to their joint, such as kief or hash, to increase its potency. These infused materials can significantly boost the THC content of your joint, so it's essential to be aware of the additional cannabinoids you're consuming.


Adding concentrates like wax, shatter, or oil to your joint can also significantly increase its potency. These products can contain very high levels of THC, sometimes as high as 90%.


A larger joint typically contains more cannabis, which means a higher concentration of cannabinoids, including THC. Therefore, larger joints tend to be more potent than smaller ones.

However, it's worth noting that a larger joint doesn't necessarily mean a stronger high. The potency of the joint is ultimately determined by the concentration of cannabinoids, not just the quantity of cannabis used. In other words, a small joint made with high-potency cannabis can be just as potent as a larger joint made with lower-potency cannabis.

How much THC is in a regular joint?

On average, regular joints contain somewhere between 15-20% THC. They can be made with average THC strains or those with higher THC content, so they can often exceed 25%. The THC content of your joint will depend on the strain you choose to use.

Our house pre-rolls contain about 22-25% THC on average, depending on the strains we used to make them.

How much THC is in a joint with hash or kief?

Bubble hash and kief are concentrated cannabis products that can contain very high levels of THC. These products are typically made by separating the trichomes, which are the small, resinous glands that contain the cannabinoids and terpenes that give cannabis its effects and aroma.

When bubble hash or kief is added to a joint, the result is a much more potent high than what you would get with a standard joint made only with cannabis flower. While the amount of THC in bubble hash and kief can vary depending on the strain and quality, it is not unusual for these products to contain 50% THC or more.

To put this into perspective, a high-THC joint made only with cannabis flower typically contains 15-20% THC, depending on the strain. In contrast, an infused pre-roll made with bubble hash or kief along with that flower may start at 30% THC and can go up to 40% or higher.

How much THC is in a joint with concentrates?

Some pre-rolls can be taken to another level with a strip of shatter, wax, rosin, or live resin inside the joint. These additional cannabis products can significantly increase the potency of the joint, with THC counts that can reach as high as 70%-80%. Essentially, this is like adding a dab of concentrate to your joint, which means that not only will the THC content be exceptionally high, but the effects may be more intense as well.

For example, our Slab Donuts pre-rolls are regular joints with a strip of rosin in the center for a slower burn and added potency.

How much THC is in a joint with both concentrates and kief?

These joints are pre-rolled cannabis joints that are coated in cannabis oil or live resin and dipped in kief or bubble hash. While other concentrated joints may use other forms of dabs, twax joints are distinguished by having a thin layer of oil spread along the paper. This results in a much sweeter flavor and stronger high, with THC concentrations ranging from 75%-90%. The layer of oil used in twax joints must be thin enough to prevent clumping and ensure that the joint burns evenly but thick enough to provide a potent and flavorful experience.

We have a few good examples of this type of pre-roll in our inventory, including Baby Personalz, which are mini joints coated in live resin and dipped in kief. On the other hand, we also offer the large Canonz pre-rolls, which are made with a backwoods leaf, dipped in distillate, and rolled in kief.

Final Thoughts

If you’re exploring all of the different types of pre-rolls out there, it’s a good idea to get a closer look at what you’re dealing with in terms of potency. Regular joints average around 20% THC, while joints that contain kief or hash can range from 30-40%. Joints that contain concentrates can contain 70-80% THC, while joints that contain both concentrates and kief can contain anywhere from 75-90% THC.
