"First, however, I must mention that HEMP grows here … It grows wild as well as under cultivation … And now for the Vapour Bath ... : on a framework of sticks, meeting at the top, they stretch pieces of woollen cloth, taking care to get the joins as perfect as they can, and inside … they put a dish of red hot stones. Then they take some HEMP SEEDS, creep into the tent, and throw the seed on the stones. At once it begins to smoke, releasing a VAPOUR unsurpassed by anything one could find in Greece. The Scythians enjoy it so much that they howl with PLEASURE." (Herodotus)
Thus in 450 BC, two and half millennia before any politician first clenched a buttock in mock anger, the ancients were pleased to be at it in classical and innocent fashion.
