Girl Scout Cookies, often shortened to GSC, is an indica-dominant strain (variety) of cannabis and is a cross between OG Kush and Durban Poison. It is approximately 60% Cannabis indica and 40% Cannabis sativa. Girl Scout Cookies flowers usually have been measured to contain around 19% to 20% THC, very little CBD, and occasionally about 1% CBG. The high THC content in GSC is beloved by medical marijuana patients looking for quick relief from symptoms associated with chronic pain, nausea, and appetite loss.
