No. Opium is a black, tarry substance that smells like flowers. Beware "soapium", that shit that High Times sells that is an incense, also black, tarry, and smells like flowers.
Other types such as white or red opium are false (could be any number of things -- the red tends to be dragonsblood incense, where as the white "rock" opium PhreeX came across turned out to be violin wax, where as you have a white unnamed powder that I've never heard of being sold as opium). Please use the search engine for your further questioning, because this one's been answered 8-friggin'-million times already.
Have a nice day (counting down until this thread is closed...)
