Terpenes – Brief Overview
Terpenes are mostly responsible for the aroma of cannabis but they are also responsible for many of the therapeutic benefits of different cannabis strains, especially in combination with the cannabinoids THC and CBD. Terpenes are quite potent when inhaled from ambient air and have been shown to affect human behavior at serum levels less than 10 ng/ml. In fact, although terpenes account for less than 1% in most cannabis plants, terpenes in concentrations above 0.05% are considered potentially pharmacological active.
Carene (Delta 3-Carene)
Delta 3-carene (Carene) is a terpene found in cannabis and also in basil, bell peppers, rosemary. It has anti-inflammatory benefits. Side effects often associated with this terpene are dry mouth and red eyes. This terpene is thought to stimulates memory and help memory retention. Carene has a pungent and pleasant earthy aroma that is piney in resemblance. At high concentrations, it has also been reported to have a strong chemical smell, mixed with pine and fresh diesel.

Commercial Products
Terpene Products
Commercial terpene products are availabe for use as supplements to be used independently or in combination with cannabis-based products, including THC and CBD. Some companies promote their products by claiming the constituents in their terpene products are formulated to simulate the same terpene blends of specific cannabis strains. Upon investigation, it was not possible to find on their website evidence to confirm their claims regarding their blends, probably to protect their proprietary interests. Links to some of these products are available here for educational purposes but are not meant to recommend or endorse the products. It should also be emphasized that these terpene products do not contain THC, CBD or other cannabinoids.
CBD Products
In addition to commercial terpene products, there are many CBD products that contain terpenes. CBD products with terpenes are labeled as “broad spectrum” when the constituents have no THC and “full spectrum” when they contain THC at levels up to a 0.3%. Unfortunately, CBD products frequently do not identify their specific terpenes and their concentrations, again, probably to protect their proprietary interests.
