Good news, stoners who celebrate Pesach! Rabbi Chaim Kanievsky, whom the Times of Israel identifies as “the leading living ultra-Orthodox halachic authority,” has ruled that marijuana is kosher for Passover. Kanievsky has said pot can be eaten or smoked during the holiday, though there’s one tiny catch: it should be used as part of a medical treatment program. More from the Israeli paper:

Kanievsky stipulated that in normal circumstances the plant is considered a member of the kitniyot group of legumes and pulses that are banned on Passover among Jews of Ashkenazi origin. But, he said, if used for medical purposes, cannabis is permitted for Jews from all backgrounds.

Kitniyot include rice, corn and beans. They have always been permissible to Sephardi Jews on Passover, but have been banned by Eastern and Central European rabbis since the 1200s when they were sometimes mixed with wheat. Refraining from the consumption of wheat products is among the central facets of the Passover holiday

After smelling the leaves of a cannabis plant, Rabbi Kanievky and Rabbi Yitzchak Zilberstein, another leading Orthodox authority, decided that the plant had a “healing smell” and made the blessing for fragrant leaves.
