" Marijuana might be federally prohibited, but the Drug Enforcement Administration (DEA) has effectively acknowledged that the plant’s seeds are generally uncontrolled and legal , regardless of how much THC might end up being produced in buds if those seeds were cultivated." < I dunno, I found this from the DEA. I also found this:
" Is it legal to order cannabis seeds online in US?
You can then have the seeds shipped to you, so long as you are abiding by state law."
So the way it sounds as long as you are in a legal state, its legal to have them shipped to you
But I have also found things that say its not. Really hard to tell honestly at this point between the 2018 farm bill and many states being legal, its a mess to sort out.
