Congo is one of the most popular pure sativa strains that is bred from a cross between a Congolese X Mexican Sativa X Afghani. This dank bud has THC levels that can be up to 20%. The Congo high is often described as a feeling of elation and awareness with alertness and an increased ability to focus. This is accompanied by a light tingly body high with amplified senses and excitable energy that slowly fades into a feeling of tranquility and well-being.
