What do terpenes contribute to in cannabis?

Terpenes play a significant role in cannabis by acting as aromatic compounds that not only contribute to the distinct flavors and aromas of different strains but also influence their effects. Each terpene has a unique scent profile, which can enhance the overall experience of consuming cannabis. For instance, the terpene myrcene is often associated with earthy, musky notes and is believed to promote relaxation, while limonene has a citrus aroma and may elevate mood.

Furthermore, terpenes are thought to work in conjunction with cannabinoids, such as THC and CBD, in what is known as the entourage effect. This concept suggests that the various compounds in cannabis work together to produce varied effects, enhancing therapeutic benefits or altering the overall experience of the user depending on the specific terpene profile present.

While color and shape of the plant, psychoactive properties, and nutritional value are all important aspects of cannabis, they do not specifically involve the unique contributions of terpenes. This is why the answer focusing on the aromatic compounds that contribute to flavor and effects is the correct one.
