Following the discussion from Seed Banks-Who can we trust?:
The laws vary greatly in the states that have legalized weed in the US; there are now 8 of us, including Colorado, California, Nevada, Oregon, Washington, Alaska, Massachusetts and Maine, as well as Washington DC. I cannot speak for the others, but in Oregon you can legally give away weed, seeds, and plants. You just cannot sell them. You can also grow weed here, 4 rec plants, and 6 medical plants plus 12 non-flowering clones per OMMP grow card. You can buy weed and plants and seeds at dispensaries. You can transport a limited amount of seeds, plants and weed in state. You can even fly with them as long as you do not fly out of state.
Which is the caveat here in the US. By many state and local laws, weed is legal. But possession amounts, growing, selling and trading all varies by state. Also you cannot transport seed, weed, or plants legally across any state lines. Even hemp now is restricted. You also cannot legally ship weed, seeds or plants by US mail (which is under federal law). However, those laws do not stop people from doing it. I happen to have some clone shippers here myself. They even have diode lights in them! Technically yes, the DEA and customs can bust people for shipping seeds into and out of the US, and between states. However, I do not know of anyone that has been busted for sending Cannabis seeds. They sell hemp seeds here by the pound in grocery stores. The hemp seeds have been sterilized by irradiation, but who is to know any different? Seeds are also under the DEA limit of 0.3% THC, so that is a case for defense of being busted for seeds.
Busts here are typically for large numbers of plants and weed, and mainly during transport. I have only read one report of a bust recently of an Oregon man transporting weed, shatter/oil and seeds in Nebraska which he was taking to Pennsylvania from Oregon. He has an Oregon processing license. Or had. That will be confiscated after the bust. It was a U-Haul van full of 25 pounds of extract, sealed packages of marijuana, vials of hash oil and 3,500 marijuana seeds. So he has been charged with a felony for drug trafficking. His claim was that he was transporting weed to a legal medical dispensary in PA, but weed is not legal in Nebraska. As is interstate transport. All weed sold in state has to have originated in that state. I believe that the seeds will not even be listed in the charges against him though. The shatter and weed will be.
Being out of country. there is nothing that the US DEA will do to you, unless you are shipping huge amounts of weed here. Same with shipping out of country. Within the US it is not legal, but people do it all the time.
