You might want to check closely. As in, the poppies might not be illegal, but if there are any signs that you are, or intend to, harvest opium from them, then those sign become evidence of a felony. For example, having a copy of the book "opium for the masses" (Jim Hogshire)
or, what you believe to be legal (because you can buy the seeds at the grocery store) may not be legal, depending.
My body, my choice. Don't stop anyone from making choices for themselves, as long as it doesn't negatively affect others. If I get high and go on a rampage, there are laws to deal with the results. If I get high and don't bother anyone, leave me alone.
(I'm for recreational legalization, even of drugs I do not intend to take. Just pointing out things folks gloss over when they speak of plants).
