If you buy cannabis from specialist seed banks, you're probably already used to seeing the THC percentage on all products. The amount of THC varies greatly from one cannabis variety to another. This can make it difficult for many cannabis users to know what the THC percentage of a product specifically indicates, how different amounts of THC affect them and what to look for when choosing products containing THC. In today's article, learn everything you need to know about the THC content of your favorite cannabis products.

What THC content is already too high?

As the cannabis industry evolves, so does the overall potency of cannabis. In fact, consumers are constantly looking for new varieties and breeders are catering to them by trying to create genetic varieties with extremely high THC content. The THC content varies considerably depending on the species and variety of cannabis. Cannabis flowers usually contain around 15-25 % THC; a high THC content of around 30 % is generally considered to be found in dried buds. A medium THC content is considered to be around 18 %.

What is the highest possible percentage of THC in cannabis?

Currently, the strongest varieties of cannabis contain around 30% THC. The breeders at Royal Queen Seeds have bred several potent varieties that are perfect examples of the evolution of THC content. The theoretical maximum THC content of a cannabis flower is around 34 %, as other components such as proteins and minerals must be present in the plant in addition to THC.

What influences the potency of cannabis?

It is generally believed that higher levels of THC cause most people to become more intoxicated, except for those who are experienced with cannabis and have developed a very high level of tolerance. Consumption of varieties with THC content above 25% does cause more THC to enter the body, but does not appear to have additional health effects on the mind and body.

However, current research suggests that high THC cannabis concentrates may not always be more intoxicating than lower THC cannabis varieties.

Another factor that affects how you feel after consuming high-THC cannabis is the content of CBD and other cannabinoids. Cannabis also contains aromatic compounds called terpenes. These have a big effect on how cannabis affects the body and brain. For example, terpenes such as pinene can mitigate some of the effects of THC on short-term memory loss.

In general, the THC content of a strain determines its potency, but you should also look for the presence of CBD and terpenes. The effects of different varieties of cannabis vary depending on the type of plant. The best way to find cannabis varieties that will give you the desired effect is to contact the experienced staff at your local dispensary.
