I just finished reading "generals die in their beds" and in it, the narrator describes how drinking rum helped him cope with the killing. This got me wondering how often drugs might have been used in the trenches.
There is a myth that Lucky strike cigarettes got their name from each pack used to soldiers containing one joint, the "Lucky strike". I kind of doubt the truth of this, but it ties in with my question
Just a quick note to say that the brand "Lucky Strike" was named during the gold rush, around 70 years before soldiers would begin receiving them in their C-rations, so it couldn't have been named after some scheme to get soldiers high. The brand was also named before marijuana was even criminalized in the US, so there would have been no need for subterfuge if they had wanted to sell joints.
