Actually, the seeds of opium poppies are not regulated by the law.
It is the growing of the plant that is illegal, not possession of the seeds.
And you can totally buy those seeds online, legally.
I know this due to my research on them for survivalist purposes. After the apocalypse, it will be a valuable medicine.
I have heard that it’s not the growing of the plant that’s illegal but the slicing of the ovary to make the latex flow that’s illegal.
There are a lot of urban rumors out there. Good luck getting a variety that actually has a strong narcotic content.
