A few days ago, I had lunch in a little cafe inside a chapel built by/for John Wesley in the early 18th century. In fact, part of it is still used as a Methodist chapel now. There was also a little bookshop there, so naturally I had a browse. I spotted a pamphlet reprinting Wesley's treatise on tea. I expected this to be along the lines of "alcohol is evil, so let's encourage people to drink tea instead". But no! It turns out Wesley viewed tea as being at least as bad for you, physically, morally and socially, as alcohol.
