I dare say opium has charming, olde-worlde, Sherlock Holmes-style connotations. It was a street drug, but that was about a century ago when users would gather in opium dens in Limehouse and get wasted. However, while I understand that the consumption of opium and its derivative, heroin, is alarmingly prevalent, it has to be pointed out that it is a hazardous hobby. Still, if you can name a fragrance after this drug, why not a restaurant? I suppose that this is just another interpretation of heroin chic.
