Joint Production

That the daily 4:20 p.m. toke sessions of the San Rafael, California, teens in the 1970s eventually sparked an international movement would have terrified the church group that bankrolled the 1936 anti-pot flick Reefer Madness. The musical of the same name hits the Valley on the high holy day for stoners, Saturday, April 20.

Reefer Madness was intended to warn parents of the evils of marijuana but the overdramatic acting and implausibly heightened scenarios shotgunned it into cult classic status upon its rediscovery in the disco era. The 1998 musical by Kevin Murphy and Dan Studney raises the campiness and keeps the film’s central narrator, The Lecturer, to usher in tales of the demon weed leading young lives into ruin via death, sex, and, of course, jazz music, while slyly zinging finger-wagging moralizers.

Thursdays-Saturdays, 7:30 p.m.; Thu., April 25, 1 p.m. Starts: April 18. Continues through April 27, 2013
