Why can't you walk through a poppy field?

Walking through a poppy field can be restricted due to safety and ecological concerns. Many poppy species, particularly the opium poppy, are cultivated for their narcotic properties, and unauthorized access could lead to legal issues. Additionally, trampling the flowers can damage delicate ecosystems, harming both the plants and the local wildlife that depend on them. Lastly, in some regions, poppy fields may be protected areas, making entry illegal.
