Top 10 strongest and most potent cannabis strains
Here we bring you the strongest, most potent cannabis strains you can get your hands on in today's market. Are you ready for this list of fire genetics? Let's find out!
With all the new and exciting strains that come out every year, it’s worth making a list to highlight the very best of them. Otherwise, one could get lost browsing the hundreds, if not thousands, of strains out there. Although potency is by no means the sole indicator of a quality strain, high-potency cultivars do represent the upper echelon of cannabis breeding.
But what constitutes a strain as being “high-potency?” What is the threshold here? Well, today's top-shelf weed strains can feature potency percentages between 25–30%+. Generally, the standard for a high-potency strain is approximately 20% nowadays. Strains with more than 25% potency can be considered ultra-potent.
Cannabis is capable of exerting a slightly different effect on each individual. When the potency levels are boosted above 20%, it can augment these effects much further.
The effects of high-potency weed
There are many satisfying effects associated with the consumption of high-potency weed, and there can be some not-so-enjoyable side effects, too. For beginners, it is recommended to start with strains that have potency percentages of 15% or lower. From there, you can work your way up.
The most common effect of high-potency weed is euphoria. That's the typical psychoactive effect everyone associates with smoking cannabis. Weed is a great mood-lifter that induces feelings of bliss while allowing you to stay in control, unlike other drugs. It can support you in times of tension and put life’s worries on the back burner for a little while. Cannabis can also lead to an altered perception of time—so 15 minutes can seem like 30 minutes.
One of cannabis' most noteworthy attributes is its ability to induce relaxation—especially at higher doses—and, thus, its ability to promote a natural night’s sleep. On the downside, weed can cause acute short-term memory loss, something typically associated with the stoner stereotype. Thankfully, this is only true for the amount of time you are under its influence.
Something that most beginner smokers experience with high-potency strains is paranoia or worry. But these emotions are also temporary, and set and setting play arguably as big of a role in your cannabis experience as potency level. Being in a comfortable setting with people you trust can help mitigate negative feelings. For best results, always start with small doses of low-potency strains, if possible. If available, opt for a strain with some CBD, too.
Everybody gets red, bloodshot eyes, especially in the beginning. That's why sunglasses are a cannabis user's best friend. You can also expect a cotton mouth, a short-term phenomenon where your mouth doesn't produce enough saliva. To remedy this, keep some hydrating liquids nearby.
It should not go unmentioned that these side effects are not perceived as negative by all users. And they don't necessarily have to occur. It really depends on you and your surroundings, as well as the quality and profile of the weed being smoked. For most smokers, the positive effects far outweigh the negatives.
The 10 strongest and most potent cannabis strains
So, without further ado, here are the top 10 high-potency strains! Experienced smokers will find themselves whisked away on a fun adventure, while beginner smokers should tread with caution!
