Mistleaf

Common illicit substance
Mistleaf is probably the most common of all illicit substances. Relatively inexpensive and easy to grow in large fields,often by followers of the nature goddess Rontra– Mistleaf can be found in nearly all corners of Kaladas.
Causing only mild addiction and adverse effects, Mistleaf can even be grown, sold and bought legally in many places, such as the lands of Cequia,the Borderlands and Ulthalas.
While affected by Mistleaf, a user will often wear a dumbfounded expression or sheepish grin, a sign of the giddiness the herb causes.

Mistleaf is also known as 'Demongrass', 'Laughleaf' or 'Rontra's tobacco'.
