Beyond Indica and Sativa: The Evolution of Cannabis Classification

Beyond Indica and Sativa: the future of cannabis classification

The cannabis classification system has traditionally been overly simplistic, splitting strains into either Sativa, Indica, or hybrid categories. These labels, while handy, suggest Sativas are uplifting, and Indicas are relaxing.

Recent scientific advancements, however, are challenging these narrow classifications and proposing a more nuanced approach.

Different shades of green

Ethan Russo, a leader in medical cannabis research, highlights strains with distinctive biochemical profiles that defy the classic Indica vs. Sativa division. This limited dichotomy misses crucial details like cannabinoid and terpene levels that directly influence a strain’s effect.

Cannabinoids like CBG and CBD are unique to cannabis, playing significant roles in its effects, with THC being intoxicating and CBD being non-intoxicating. Terpenes, on the other hand, offer aromatic diversity and influence the effects of cannabinoids, making the classification based on terpenes and cannabinoids more precise.

A new mosaic

Advancements in analysis technology, such as Phyto Facts, have enabled more accurate mapping of terpenes and cannabinoids in cannabis strains. This allows for a deeper understanding of a strain’s potential effects, tastes, and smells.

With this advanced mapping, consumers are better informed about what to expect from each strain in terms of relaxation, taste, aroma, and essential component concentration like CBD and THC.

A wider menu

The traditional Sativa-Indica classification is becoming obsolete, as a more detailed examination of terpenes and cannabinoids reveals overlaps between the two categories. This shift leads to a more accurate prediction of a strain’s effects based on its terpene and cannabinoid profile rather than its traditional classification.

Identifying the dominant terpenes in a strain, such as limonene for its citric scent and pain relief benefits or linalool for its soothing effects, offers a clear path towards understanding each strain’s unique characteristics.

Old and new labels

The simplistic Indica-Sativa labels no longer suffice in accurately describing a cannabis strain’s effects, as the presence and concentration of specific terpenes are influenced by breeding and cultivation choices. Researchers from Dalhousie University have shown that certain terpenes are more prevalent in either Sativa or Indica strains, affecting their aroma and effects.

Recent developments by the University of New Mexico researchers have led to a pioneering cannabis flower classification system. This new system, focusing on chemovar, allows for a more informed selection based on a strain’s phytochemical properties, significantly enhancing predictability of effects and potential side effects.
