The traditional method is to roll out the opium into long rolls, like licorice. then mix headache powder into it, like "Goody's," then break into pea sized balls. For smoking, you need a pipe of course, and a candle or similar low heat flame. You need to have a crochet needle [in lieu of the traditional utnesil] and place one of the pea sized balls onto the end. Once it is on, place it about 6 inches above the flame and rotate it evenly. After 8 to 10 seconds remove it, while still on the needle, mold it into a cone as best you can between your fingers, and then hold the needle in your hand. With your other hand, warm the bowl of your pipe over the flame for a good 45 seconds or so. When it is good and hot, place the cone of opium in the bowl of the pipe and inhale. you do not apply a flame to the bowl or the opium. It is much more akin to smoking freebase cocaine. You want to vaporize the substance via a prewarmed surface, as opposed to buring it with a flame. the headache powder is a traditional component that is said to cut down on the adverse side effects.
You can simply put it ina weed pipe and light it, but you would be wasting a very good thing and not really smoking opium per se.
Far better than smoking though, is to take the pea sized balls, do not warm them, just wrap them in rice paper and place them in your rectum. It is a much more effective experience, and a whole lot easier. Of course, if you really just want to experience "smoking opium,"...
