An opium den.
Opium, especially in its liquid form Laudanum, was widely used in the 18th and 19th century. It is startling how many actually were opium addicts at that time.
If anyone is interested in this subject, I recommend reading the 'confessions of an english opium-eater'. If you get beyound the quiete lengthy style of writing (it was written in the 1820'
, it is really an interesting time-document.
