The story goes the origins of the Chemo strain (aka UBC Chemo) date back to the 1970s where this strong 90 percent indica strain was developed by the Canadian government in the '70s for chemotheraphy patients. Chemo has a reported THC content of around 20 percent. The aroma is woody with a spicy chocolate flavor with hints of floral. Some may find Chemo too heavy for daytime use, but it provides relief from nausea and lack of appetite, pain and insomnia.
