Afghan kush may be one of the most popular marijuana strains the world has ever seen. Though this strain isn’t as powerful as its long history suggests (THC levels at about 17-20%%), this strain is certainly strong enough to deliver a deep, sedated body high with a strong shot of euphoria. CBD levels are low, considerably less than 1%. A near-pure indica (sativa/indica ratio of 5:95), this strain was named got its name from its home country, where it grows in the Hindu Kush Mountains. This is close to the mountainous region where humans first tamed wild cannabis thousands of years ago.
