Headbanger is a sativa-dominant cannabis strain that won the 2013 Amsterdam Cannabis Cup and is a cross between Sour Diesel and Biker Kush. It's known for its powerful, uplifting, and euphoric effects that are primarily cerebral, making it suitable for focus and creativity but not recommended for beginners. The aroma and flavor profile is a mix of sour, diesel, citrus, and sometimes spicy or peppery notes.
