I've never gotten any other opium-based smells - this one was a freebie so I have little comparison for a lot of the ingredients - but what they all amount to on me is a really heated, sexual smell. This is the smell that wafts off the skin after hours of cavorting in the summertime: thick, hot, luxurious, and stunningly similar to... well... sexy human. I have smelled sexy-human smell on myself and forgotten I wasn't wearing Event Horizon!
Needless to say, when I went back and read the description, I was pretty surprised at the mood intent - this is a bedroom smell through and through!
