Shoshana Feinstein produces. Since its original Off-Broadway production in 2001, Reefer Madness has achieved a cult status in the vein of The Rocky Horror Show and Hedwig and the Angry Inch, due in part to the award-winning 2005 Sundance film adaptation.

Inspired by the over-the-top 1936 anti-pot propaganda film of the same name, Reefer Madness, according to press notes, "takes a tongue-in-cheek look at the hysteria caused when clean-cut kids fall prey to marijuana, leading them on a hysterical downward spiral filled with evil jazz music, sex and violence."
