This thread is silly.
Cannabis is wind pollinated. It does not produce nectar and the male flower structure does not lend itself to pollen-exclusive collection by any insect, since stamens and anthers hang down and release pollen in clouds of individual spores which do not clump. Insect pollinated flowers are adapted to allow pollen to be a collected-- vertical orientation and pollen that aggregates in clumps easily. Bees might be attracted to resins on the plant for propolis, but in my experience tree saps are much more likely sources.
Papaver is a different matter all together. Most poppy genera have bee adaptations and are very, very abundant pollen producers. The flower structure tends to have hundreds of stamen/anthers. Bees will work wheatfield poppies, iceland poppies, the "california poppy" and the "garden poppy"-- which is really just a denatured opium/poppyseed plant. Locally we have a lovely large perennial poppy, Romneya coulteri, which makes a bright yellow pollen, and bees loaded with this can be counted returning to the hive in large numbers. Most poppies are fragrant, a good sign that insect pollination is their selected strategy, the pollen clumps readily. The iceland poppy, Papaver nudicaule, and the Oriental poppy, Papaver orientale, is planted widely as a spring annual, often in large colorful beds. Its nectar tends to be a diffuse exudation on the pod, rather than a droplet. The bees push through the dense mass of stamens to lick the pod, three or four bees will work a single large flower. It is quite the show.
The Garden poppy, Papaver somniferum, produce a milky white latex sap from any damage to the leaf or capsule, I haven't observed bees collecting the drying sap which is raw opium.
