Whether you're new to cannabis or you've been enjoying the herb for some time, sooner or later you’re going to want to know what the most potent types of marijuana are. When we talk about the “potency” of marijuana we mean the concentration level of Tetrahydrocannabinol (THC) – the main psychoactive compound in cannabis plants – found in a particular strain. However, we must remember that everyone experiences the mental and physical effects of each type of marijuana differently.



As cannabis breeders create new hybrid strains every year, we are continuously given new types of marijuana that are more potent than their predecessors. There are now cannabis strains that consistently test at concentration levels of more than 25% THC, and breeders still aim for more potent marijuana varieties. To give you an idea of what the strongest strains of cannabis are we list five of the most potent marijuana varieties currently on the market.

1. Girl Scout Cookies is a hybrid strain that consistently tests as high as 28% THC and induces an uplifting, euphoric cerebral experience. This popular strain produces knotty green flowers with orange-red hairs that emit a sweet, earthy aroma. It's often used to relieve chronic pain and relax the body.

2. Gorilla Glue #4 consistently tests as high as 28% THC, with some strains testing at 30% THC. This high-yielding variety is the most potent member of the Gorilla Glue family of cannabis strains, and it produces big, pungent flowers that smell of earth, wood, and pine. It produces a strong psychoactive experience, and physically sedative effects wash over the entire body.

3. Bruce Banner is a strong, sativa-dominant hybrid that consistently tests as high as 30% THC. Named after the alter ego of the Incredible Hulk, it provides a powerful body buzz and a stress-free cerebral experience. It's a fast-acting type of marijuana that leaves users feeling happy, creative, and relaxed.

4. Tutankhamon (AKA King Tut) is a sativa-dominant cannabis variety with a THC content that consistently reaches almost 30%. The flowers smell of sweet fruit, spring flowers, and damp earth, and they induce an energetic, cerebral buzz that's good for social situations.

5. The White consistently tests between 18-29% THC and has potent effects on both body and mind. This mysterious hybrid is known for its dense coating of white, crystalline trichomes and almost complete lack of odor and flavor.
