If you’ve spent time reading through the websites of dispensaries, you’ll know that many (though not all) include the lab test results of the products that they have in inventory. Included in the test results is the actual percentage of THC it contains.
Given that THC is the compound in marijuana that gets you buzzed, logic would indicate that a higher percentage product would lead to a stronger high (than some other lower THC% cannabis). Logic, however, doesn’t always apply and that’s certainly the case here, as other significant factors can come into play.
Here are some of the elements in addition to THC % that play a role:
Dose: No shock here…the gross amount of THC you consume matters. A joint with a high THC percentage for example, might still provide a mild high if you consume a small amount of it. Conversely, a lower THC joint can lead to an impressive high if taken in large quantities.
Tolerance: Regular cannabis users (older stoners) often develop a tolerance to THC, meaning they require higher doses to achieve the same effect. Beginners and infrequent users can be more sensitive to THC. Thus a small amount can pack a hefty punch.
Cannabinoid Profile: Cannabis contains other cannabinoids besides THC, such as CBD. The ratio of THC to CBD and other cannabinoids can influence the type of high you experience. CBD can soften some of the psychoactive effects of THC.
Terpenes: Terpenes are compounds found in cannabis that impact the effects of THC. The myriad of strains you will see on the menu of any dispensary each contain their own unique terpene profile, which can lead to different types of highs. For example, terpenes in Indica strains are intended to foster relaxation, while Satica ones may deliver a “heady”, get you moving experience.
On a macro level, an 85% THC vape pen will likely give you a stronger high than a 70% one, but as you can see above, there are a number of different factors that can all play a role in the high that you enjoy.
