Many are familiar with stories of great tzaddikim smoking pipes and the like in some sort of kabbalastic rite. I've even heard some chassidic Rebbes having a so called "Kabbalah pipe". Im curious to know if perhaps marijuana was used to induce meditational states. Other places (including in the books of Rabbi Aryeh Kaplan) have mentioned deep meditational states of Kabbalists brought about through psychedelic substances.
Twofold question: Is there some source in kabbalah for the use of any drugs to reach higher levels of connection?
And/or any sources for kabbaltic meditation using smoke?
