New users beware: Deadhead OG is not for the faint of heart. With THC levels that surpass 20%, this strain is quite potent and should be handled with caution. Deadhead OG combines genetics from parent strains SFV OG Kush and Chemdawg 91, and it has become a fan favorite among West Coast aficionados. Useful for pain and high stress, this strain provides users with such effects as full-body relaxation, a sense of blissful transcendence, and a mood boost. However, it can also lead to intense sedation due to its power, so it should be reserved for night usage.
