You can even make tea out of poppy seeds that is pretty similar to opium. Dried pods (take the seeds out and do w/e you want with them) work better. Just give them a careful look to check that they haven't been cut.
Poppies are ridiculously easy to grow. You pretty much throw the seeds on the ground and forget about them until harvest. Hens and Chicks look really cool and are supposed to be very potent. This is the first year I haven't grown poppies (strictly for scenery, opium can't really touch my tolerance).
I agree with everyone who is saying don't buy opium unless you know who made it. Analysis of seized "opium" shows it is almost all fake or a mix of tar and incense or another cutting agent. A gram of opium has on average 100mg of morphine. 40-50mg of heroin will mimic that perfectly. That's about a bag of heroin, which can cost anywhere from $4-7 depending on connection and bulk purchased. If purchased in real bulk it'll be way cheaper. Dope is way more available than opium, and seems way more innocuous.
.... while opium IS addictive, it is nowhere near the level of refined heroin.... and even if you did get "hooked" on opium, good fuckin luck growing enough to supply your habit
