Indica and Sativa Labels Can’t Be Trusted, Study Indicates

High Times

Most indica and sativa labels on cannabis are incorrect, results from a new analysis show. Cultivars are generally sold as indica, sativa or hybrid of the two, promising energizing or calming effects, but this classification system probably amounts to nothing more than a trend that refuses to die.  A new study published October 14 in Nature Plants re-analyzed nearly 300 samples of cannabis, and found surprising results. Researchers from Dalhousie University in Nova Scotia, Canada joined a team from Wageningen University & Research institute in the Netherlands to process the data. Researchers gathered and analyzed 297 samples, which were previously quantified for terpene and cannabinoid content, as well as genotyped for over 100,000 single nucleotide polymorphisms. The results indicated that sativa- and indica-labeled samples were “genetically indistinct” on a genome-wide scale.  “Growers worldwide label their cannabis strains quite subjectively with the terms ‘Indica’ and ‘Sativa.’ There’s nothing scientific about that. Unfortunately, retailers and consumers cannot rely on the labels that are stuck to the jars,” said Dr. Sean Myles, Associate Professor at Dalhousie University’s Faculty of Agriculture and lead author of the study. “There is now a broad scientific consensus that the current use of the Indica and Sativa labeling is misleading: these labels do not provide reliable information about the genetic or chemical makeup of the plant.” Check Terps Instead for Effects While labeling cannabis as sativa or indica is a poor and unscientific way to categorize cannabis, researchers noted that labeling cannabis by certain terpenes is probably a better way. “Our results demonstrate that the Sativa–Indica scale currently used to label Cannabis poorly captures overall genomic and metabolomic variation,” researchers wrote. “Cannabis labeling is instead probably driven primarily by a small number of key terpenes whose concentrations contribute to the characteristic aromas commonly associated with Sativa and Indica…
