Cannabis affects everyone differently. One strain might leave you energized and focused, while another induces deep relaxation or sleepiness. The key to these varying effects lies in the plant's terpenes—the aromatic compounds responsible for its distinctive smells and, more importantly, its physiological effects.
Choosing Cannabis Based on Terpenes
Instead of relying solely on the "Indica" or "Sativa" labels, consider the dominant terpene profile of a strain to predict its effects:
- Sedating/Relaxing: Look for strains high in myrcene or linalool.
- Energizing/Focus: Opt for strains rich in terpinolene or limonene.
- Mood-Boosting: Strains with limonene or caryophyllene may be beneficial.
The Strain Guide app is a valuable tool for tracking terpenes and their effects, helping you make informed decisions when selecting cannabis strains.
What Are Terpenes?
Terpenes are naturally occurring compounds found in cannabis and many other plants. They play a crucial role in determining the plant's aroma and can influence its effects on the human body by interacting with neurotransmitter systems. For instance, myrcene, a common terpene in cannabis, has been shown to have sedative properties, while limonene may have mood-enhancing effects PMC.
How Terpenes Affect Your Brain
Cannabis terpenes interact with the brain's neurotransmitter systems, influencing mood, energy levels, and cognition. For example, myrcene enhances GABA activity, promoting relaxation and sedation, while terpinolene increases dopamine and norepinephrine levels, leading to heightened alertness and focus PMC.
Terpene Profiles in Cannabis Strains
A 2017 study by Booth et al. identified the terpene profiles of various cannabis strains, highlighting the diversity in terpene composition and its potential impact on the effects experienced by users PLOS.

🧬 Genetics and Terpene Expression
The expression of terpenes in cannabis is influenced by its genetic makeup. A 2017 study by Booth et al. identified genes responsible for producing different terpenes and categorized strains into myrcene-, terpinolene-, and limonene-dominant clusters PLOS. These genetic factors play a significant role in determining the effects experienced by users
