A terrible new drug your own parents are taking right now!

“This drug is especially efficient in producing nightmares with hallucinations which may be alarming in their intensity. Another peculiar quality of it is to produce a strange and extremely degree of physical depression. An hour or two after it has been taken a degree of sinking may cease upon the sufferer so that to speak is an effort. By miseries such as these the best years of life may be spoiled.”

— The Regis professor of physics at Cambridge, in, writing about tea in the early 20th century
