Thucydides is a far better option , being at the beginning of the record for the continuous record of reliable historical writing.
In my case, Herodotus was describing a Scythian practice (the use of cannabis) that we've been able to corroborate, in its broad outlines, using archaeological finds, which to my mind makes it reliable enough to use.
If anyone's interested, this is a quote from the paper, which is a work in progress and not published yet: When Herodotus described the purification practices of Scythians following elite burials, he wrote of a ritual involving the construction of a tent-like enclosure of “wool mats.” At the center of this enclosure, the Scythians threw cannabis onto “red-hot stones, where it smoulders and sends forth such fumes that no Greek vapor-bath could surpass it.” According to Herodotus, “the Scythians howl in their joy at the vapor-bath.” The term Herodotus used here – κάνναβις, or kánnabis – was a loan-word from Old Persian (kanab). From Greek, it made its way largely unchanged into Latin (cannabis) and from thence into the Romance languages and English." [Citing A. D. Godley, trans. The Histories of Herodotus (Cambridge, MA: Harvard University Press, 1920), 4.74-6.]
Not only am I interested to hear that "hot boxing" is an ancient practice, but also the sense of immediacy that I now have with ancient Persia over our shared etymology of kanab.
As an aside, the Scythians were not in what we'd today consider Persia (Iran). They originated around the north coast of the Black Sea, and extended east and southeast from there along the Eurasian steppe.

“Reading the literature on the word for ‘Cannabis’ in the languages of Eurasia soon puts one in mind of what one is told frequently happens when the authorities conduct a raid to confiscate Cannabis and attempt to identify to whom it belongs: everyone involved says it belongs to someone else, generally someone conveniently not present at the moment.” [0] Some dictionaries claim a Scythian origin.

A word that was spread among numerous languages and cultures, usually in connection with trade, so that it becomes impossible to establish its original etymology, or even its original language.
Interestingly even back in Egyptian times there was a corroded version with H instead of C: 𓎛 𓆰 𓈖 | H.n | cannabis
(unless 𓎛 was closer to C than to H)
