THC explained
As time goes by, we learn more about the majestic marijuana plant and its benefits. One of the many cannabinoids found in weed has particularly stood out amongst its peers. Tetrahydrocannabinol, or THC, remains the key ingredient in judging the intensity of a high.
Marijuana breeders are creating high THC strains with the potential to reach astronomical percentages. In recent years, we’ve seen these values pass the 30% mark and truly push our tolerances to the edge.
These strains with high THC levels have etched their names in our minds, earning a strong reputation as well as our respect. What’s even more amazing is that beginner growers can harvest many of these cultivars right in their backyard.
Each weed variety offers something unique. High THC sativa strains bring on energy that’s hard to describe. These cultivars are perfect for daytime tokers and have the ability to trigger mental clarity, creativity, and motivation.
On the other side of the spectrum, we get high THC indica strains. This type of cannabis provides users with complete relaxation. You’ll find cultivars of this variety work well as a nightcap, ridding yourself of daily stresses and melting you to the couch.
There’s also a third type that has become synonymous with the medicinal community. These high CBD and THC strains give patients the option of an alternative treatment. If you fall into this category, make sure you consult your doctor before using marijuana as a medicine.
