Now this caused immense heat and Shiva started getting restless. A restless Shiva is not a good omen. Hence the gods undertook the task of cooling Shiva off. According to one of the legends Chandra Dev (Moon god) made Shiva’s hair his abode to cool him.
Some legends even claim that Shiva moved to Kailash (which has subzero temperatures all year round) post the Samudra Manthan episode. Shiva’s head was covered with “Bilva Patra”. So you see everything was being done to cool Shiva off
Now coming back to the question – Marijuana is supposed to be a coolant. It lowers down the body’s metabolism and that brings the overall body temperature down. Same is the case with Cannabis (Bhang) and Datura. Bhang and Datura are closely associated with Shiva as well.
