What are the strongest cannabis strains?

Looking for a weed strain that will challenge your tolerance or stand up to stubborn medical symptoms? Readers ask us all the time which strains are the most potent, and while that depends on a variety of factors from how it was grown to the quality of genetics, we’ve put together a list of strains that have a reputation for heavy-handed euphoria. Browse strains

While THC is the main driver of potency in weed, it’s important to understand the role terpenes may play in enhancing and shaping the strain’s high. Terpenes like myrcene, caryophyllene, and limonene refer to aromatic compounds that lend cannabis its unique array of smells, and a cannabis strain rich in both terpenes and THC often delivers a more remarkable experience than a product that lacks chemical diversity. What are cannabis terpenes and what do they do?

The below cannabis strains are just a selection of popular powerhouses, but keep in mind that there are many more options and frontrunners out there. You can also filter for “potent strains” on Leafly dispensary menus to see if any of these recommendations are available near you. And remember the adage “start low, go slow” with these ones.
