XJ-13, also known as "XJ13" and "XK Thirteen," is a hybrid marijuana strain made by crossing Jack Herer and G13. It has a delicious taste which is spicy and sweet at the same time, delivering notes of lime and pine and a potent smell with funky undertones. The high kicks in almost immediately, giving a powerful and motivated disposition due to its uplifting effects. The cerebral effects are well endowed accompanied by a body buzz unlike any other.
