How Will Climate Change Affect Cannabis?


A report by the International Panel on Climate Change (IPCC) suggests that we are fast approaching a global crisis. Such an outcome is sure to have significant repercussions for us all. However, several studies have suggested that cannabis may thrive as a result of climate change. Decreased rainfall, higher temperatures, and increased levels of carbon dioxide in the air can dramatically affect the growth of plants and may result in higher yields of cannabinoids.

Cannabinoids like tetrahydrocannabinol (THC) and cannabidiol (CBD) help protect cannabis plants from various environmental threats. Over the years, growers have developed numerous stress techniques that cause plants to increase their production of these desirable compounds. Climate change will undoubtedly heap extra stress on cannabis plants and could therefore result in higher cannabinoid yields. To test this theory, researchers recently investigated the impact of drought on cannabis. While growing a cultivar that typically produces 5.66 percent THC and 10.3 percent CBD, the study authors withheld water for around 11 days during the flowering phase, causing plant water potential levels to drop significantly. Tetrahydrocannabinol acid (THCA) concentration subsequently rose by 12 percent, while cannabidiolic acid (CBDA) concentration increased by 13 percent in these drought-stressed plants. Flower size also increased, meaning that overall THC yields were 50 percent higher than in plants that received ample water, while CBD yields were 67 percent higher. Obviously, extended droughts are harmful to all plants, so it’s impossible to say whether climate change will benefit cannabis in this way. However, this study provides some fascinating insights into the possible impact of future droughts on cannabis plants. The Contradictory Effects Of Climate Change On Cannabis In all likelihood, the consequences of climate change will be a…
