Ah, there’s nothing like opening a bag of weed and taking a deep refreshing breath of nature. That nostalgic smell is so familiar and has the capability to transport you to the very first time you smoked. You have terpenes to thank for that.
Cannabis is full of different compounds: namely cannabinoids, flavonoids, and common plant compounds. The cannabinoids we’re interested in are THC which induces the high associated with cannabis (obviously) and CBD which is rapidly becoming more popular especially due to its pharmacological functions without the high. There are many other cannabinoids in cannabis like CBG, CBN, THCV, THCA and more.
Next up are the flavonoids, these produce non-green pigmentation in plants as well as enhance flavor, enhance smell, and are pharmacologically active.
Lastly are the common plant compounds like fatty acids, polyphenols, lipids, waxes, and terpenes. Terpenes are non-psychoactive hydrocarbons found in the essential oils of plants. They give each strain of cannabis its unique fragrance and taste. Some terpenes that contribute to the smell of cannabis are pinene from pine trees, limonene from citrus fruits, linalool from lavender, terpinolene from oregano and cumin, citronellol from geraniums, and myrcene from hops.
