Tûkamûr

Tukamur is a bluish-green grass native to semiarid to temperate shortgrass prairies. Tukamur contains a powerful, dangerously addictive euphoric drug which is  prepared by  boiling the  grass, straining the extract,and boiling  again to  condensing the  extract into  a syrup. It allows two users, both  under the  influence of  tukamur  syrup, friendly to one another,  and lying  within a  range of 50 miles times their average level to share dreams. If eaten raw, tukamur grass is sweet and  mildly euphoric. In many areas, tukamur has been eradicated by herders attempting to keep livestock away from it.
