Deep Dive: Cannabis Trichomes are Cannabinoid Factories

Updated: Mar 6, 2023

This Deep Dive serves two roles: First as a homework assignment for the Cannabis Foundation: Part 1 course and second as part of Higher Learning's Deep Dive Subscription.

For Deep Dive subscribers: This Deep Dive serves as a research review that summarizes four peer-reviewed research studies on the topic of CBD for mood disorders. This article is a living document that is updated regularly based on the release of new research on this topic.

For students of Cannabis Foundation: Part 1, welcome to the first homework assignment for Module 1: Cannabis 1 > Lesson 4: Trichomes. In this assignment, students will learn about the chemistry and business significance of glandular trichomes. This assignment teaches students the results of a 2021 study about the trichomes of cannabis/hemp/marijuana plants that produce nearly all of the cannabinoids and terpenes within the plant.

This 2,000-word in-depth study summary teaches students the details of cannabis trichomes, including the purpose, function, and overall role of trichomes. It explains the three types of glandular trichomes (non-glandular trichomes also exist) and the factors that affect the terpene and cannabinoid yield of trichomes.


A September 2021 research study entitled "Cannabis Glandular Trichomes: A Cellular Metabolite Factory" that was published in the journal Frontiers in Plant Science provides an overview of "our current understanding of cannabis glandular trichomes and their metabolite products to identify current gaps in knowledge and to outline future research directions." The study involved researchers from Germany, Israel, and China.
