Yes you can smoke raw opium. It's probably easier to just eat it but of course you can dose better with smoking. Put it on some tinfoil and heat it sorta lightly from underneath, just like smoking heroin. I don't see why you wouldn't want to just dry it out though. There would probably be carcinogenic substances in there like some smoke from the high amount of plant matter that's in there, though, like James said above.
If I were you, I'd dissolve it in hot water - about 40ºC (you don't need to use much water, but you're not doing a CWE so it doesn't matter if you use too much), then filter through something that is closer to a rice sack than lab grade (so you can make sure you get any undissolved alkaloids). That's just to get plant matter out. Then you can dry it in the sun and smoke what's left.
If you think you're a bit of a chemist you could get fancy and add some calcium hydroxide/slaked lime to the solution before drying it to convert the insoluble morphine into a water soluble salt calcium morphenate. You can then filter it through a coarse fabric like burlap and the liquid that you get contains mostly morphine and a little bit of codeine. No where near pure enough to inject but plugging might be an option. Not really a good way to dose w/o drying and weighing, and even that would be inaccurate
whatever you decide to do, ddrying is probably the best option
