Herodotus documented that the Scythians were hot-boxing marijuana:
‘They anoint and wash their heads; as for their bodies, they set up three poles leaning together to a point and cover these over with woollen mats; then, in the place so enclosed to the best of their power, they make a pit in the centre beneath the poles and the mats and throw red-hot stones into it… The Scythians then take the seed of this hemp and, creeping under the mats, they throw it on the red-hot stones; and, being so thrown, it smoulders and sends forth so much steam that no Greek vapour-bath could surpass it. The Scythians howl in their joy at the vapour-bath. This serves them instead of bathing, for they never wash their bodies with water.’
(Histories, Book 4)
FWIW Cannabis seed has nearly zero THC.
They are used in TCM as a mild laxative and have been for about 2,000 years but they make a decoction with them not a steam bath.
