What to Look for in High THC Strains

What to look for in high THC cannabis strains infographic

A high THC strain is a marijuana strain that contains a high amount of tetrahydrocannabinol, or THC. This ingredient causes the psychoactive effects in cannabis. Any strain containing over 20% THC is considered a high THC strain.

The higher the THC content of a plant, the stronger the effects. A single puff of a high THC strain can cause a strong high in a person. Beginners should start with low THC strains and try out the high THC strains on our list once they’ve built up their tolerance levels.

Strains like Godfather OG and Chemdawg will always have a market with harder smokers who smoke daily and have high tolerance levels. These smokers can only get the high they need by smoking a high THC strain.

There’s also a market for low THC strains, and this is exemplified in medical marijuana. Marijuana strains that have sub 0.3% THC content are considered medicinal strains and won’t get a person high. They are used for the relaxing properties of cannabis.

Wrap Up:

Strongest strains of cannabis infographic

Testing the potency of a strain can be done using THC Gas chromatography (GC) and High-Performance Liquid Chromatography (HPLC). Strains are tested in professional laboratories and sometimes marijuana dispensaries.

The test results vary based on the way the plant was grown. A plant that was grown outdoors under the sun can have a higher THC content than a strain grown indoors. This means you’ll never experience the same high if you try the same strain in different locations.

The maximum THC a strain has ever tested was 35%. There are artificial ways to increase the potency of cannabis, such as laboratory THC extraction. The THC is extracted from the plant and used to make concentrates like Live Resin, Live Rosin, and others.

We only recommend high THC strains for daily smokers who already have a beefed-up tolerance. The strains listed on this page are the most potent in the world, and the only way to consume THC in higher amounts is to smoke concentrates.
