There's a certain mystique around the whole notion of smoking opium. From pictures or paintings of 'opium dens' full of patrons (literally) lounging around, taking hits from their super long pipes, to the actual pipes which can be ornate and beautiful in and of themselves. I assume that this is part of the reason why people with little to no experience consuming opium often seem to be obsessed with the idea of smoking it rather than just eating it or making tea with the available material.
As HeadphonesandLSD said:
For the vast majority of people who grow a few plants for themselves, the most simple way is the best. Once pods have matured and dried, you can collect the pods, blend them and use the dried pod material to just make a tea. This is the easiest and most effective way to use the small amount of pod material you've spent months cultivating. And just because this is dead simple, it doesn't mean this isn't a good method. There are dozens of variables to consider (the amount of pod material you have, the strength of the strain the pods belong to, the user's body size and their tolerance to opiates, etc etc), but it's pretty hard to fuck this up completely, and you're fairly likely to get a very pleasant, deep, zen-like sense of calm and relaxation which lasts for many hours.
Inexperienced people who try to create smokable opium with their first batch of plants generally end up with a whole lot of disappointment. Many years ago there were loads of 'teks' for shit like so-called "cooked flake opium", and while I'm sure some people got some amount of success from some of these guides, I often found them to be an effective way to lose a good portion of the yield you'd painstakingly collected and obsessed over for months. Also, in hindsight it's kind of funny now, but the number of times people on some forums (like poppies.org I think was a good one if I'm remembering the name right - or papaversomniferum.com?) would post their experience about following these teks to the letter, step by step, and then coming to the forum to complain that it didn't work and they lost their precious raw opium latex, only for the OP to update and say "oh my bad, I forgot to add <critical step> between steps 4 and 5...."
For 99% of people who are just growing a few plants discreetly for themselves, it's so much better just to follow the KISS method (which is 'Keep It Simple, Stoner').
