It’s an indica-leaning hybrid strain that has THC levels cresting 35%, and some say that it could be even higher.

Citral Glue

Sativa-Dominant Hybrid

Citral Glue: Combine Citral Skunk with Original Glue and what do you get? This potent (22% THC) sativa-dominant hybrid is rich in the caryophyllene terpene. While Citral Glue is a beautiful bud decorated with red fibers, it’s aroma is probably its most unique feature—take a splash of diesel fuel, drop in some orange slices, and add a little skunk to it. That’s Citral Glue.  

Death Star

Indica-Dominant Hybrid

Sci-fi cannabis fans unite. This caryophyllene-rich indica-dominant hybrid strain is a cross between Sensi Star and Sour Diesel, and you’ll know it because of the smell.

Many cannabis enthusiasts like to enjoy Death Star before bed, but it can truly be consumed any time of day. Just be ready for it: it has 18% THC.  

Strawberry Banana or Strawnana

Indica-Dominant Hybrid

Kosher Kush or Kosher OG


This indica strain is potent—21% THC—and for good reason: it’s related to OG Kush, which is a classic strain in the cannabis world. Kosher Kush has an earthy aroma thanks to its myrcene terpene, and some people even report a slightly fruity undertone too. Kosher Kush has won a number of High Times Cannabis Cup awards, so you know it’s going to be good.

Did you know cannabis comes in a variety of flavors, including grape and strawberry?

What Makes a Strain Strong?

In general, most people look at THC potency to determine if a strain is strong or not. Experts, however, feel it’s also important to look into the strain’s terpene profiles. Terpenes are another compound found in marijuana that work with cannabinoids and flavonoids to create the experience you have when consuming marijuana. This is because all of these pieces work as a whole within your endocannabinoid system in unique ways that we’re still studying.

Because everyone is unique, it’s also true that what some cannabis enthusiasts consider a strong strain, others aren’t really affected by. Whether a strain is strong or not depends on you and your body.

Are Strains Getting Stronger?

Yes, strains are definitely getting stronger. In fact, the U.S. Drug Enforcement Administration has even acknowledged that the marijuana they seized in the early 1990s had an average THC potency of less than 4%. In 2018, the seized marijuana’s potency averaged over 15% THC. 

Growers and manufacturers are always driven by the market. As long as cannabis enthusiasts continue to call for stronger and stronger marijuana strains, the market will continue to produce them to the extent allowed by the plant’s properties. There are pros and cons, however, to these stronger strains.   

What Are the Pros and Cons of Strong Strains?

As with most things, there are benefits and disadvantages to strong marijuana strains. In general, it comes down to the individual cannabis consumer. For example, one cannabis enthusiast may really enjoy the psychoactive effects of high-THC potency strains. Another cannabis enthusiast may have a poor experience with high THC strains, like anxiety and paranoia. Here’s a list of some of the pros and cons of strong strains:

Pros of Strong Strains

  • Faster results: In many cases, the stronger the strain, the faster you’re going to feel the qualities of the strain, both psychoactive and otherwise.

  • More intense experience: For those that want it, a strong strain can lead to a more powerful session. 

Cons of Strong Strains

  • Amplified experience: Some people report dry mouth, red eyes, couch lock, and more with certain strains. With strong strains, these feelings can become overwhelming.

  • Higher tolerance: If you regularly consume strong strains of marijuana, your tolerance for THC can increase. This means to achieve the same psychoactive response, you’ll need to consume more. When this happens, many cannabis enthusiasts take a break from cannabis, allowing their tolerance levels to reset. 

Ultimately, if you want to try strong strains, start slow with a low dose and see how you feel. If you decide the cons outweigh any positives, stick to the more common strains. There are plenty of them to enjoy too!
