Yes, harvest the opium, and enjoy it. I did this in college and me and my buddy split all our opium in half. He decided he was going to try to turn his into heroin. I was like dude, this shit is amazing on its own why? But he insisted. All the glorious goop he had and he came out with like two small hits worth because he had never done the synth before and thought it would be "so easy"
After that he was begging me all the time to break him off a piece and I did for a while but he ended up smoking a whole shit load without offer of any compensation for a long time. When I eventually cut him off I wanted to enjoy what little I had I didn't want to sell it much less give it away to someone who wasted all there own on a stupid experiment. Opium is great and will get you high as shit.
