Refers generally to cannabis-based therapy but could also refer to other
psychedelics, or more broadly to embracing nonchalance. Pending context, the expression could be an
invitation to others to partake in an activity, or a declaration of
indifference to one's carefree decision making. The expression is generally used without punctuation, similar to Marvin Gaye's 'What's Going On', and is also seen abbreviated to WNM.
