Hemp and cannabis plants do not produce nectar, but their pollen can keep bee populations happy and well-fed. Specifically, the study found that bees not only love the pollen from cannabis and hemp plants — they also can benefit from the plants’ abundance of pollen as a subsistence resource during times when local flora diversity has been stripped due to modern farming practices or a natural occurrence, such as drought. Bees are especially drawn to larger crop plots and taller plants, meaning industrial hemp carries the most benefits as an industry for the bees.
They found huge numbers of bees thriving around weed plants, which are a ‘newly introduced and rapidly expanding crop in the American agricultural landscape’. The bees are unlikely to get too buzzing when romping around the weed fields because the plants are actually hemp crops and therefore have lower levels of THC – the active chemical which gets you high.
