seeds from Holland are obviously due to the relaxed views on Cannabis and its status as decriminalized. There are TONS of seed dealers around Amsterdam and Haarlam - Even in the flower markets they sell kind bud cannabis seeds. It is just "normal" there. And when im there, i feel "Normal".
England is starting to get that way too - recently Cannabis was reclassified as a very very low concern. Seeds are now starting to be sold as curiousity items not intended for germination (but they will). Germinated seeds are against the law in England currently.
Canada is not decriminalized or reclassified - they have just agreed not to enforce the laws "heavily". I interpret this as meaning - if your just growing for yourself, your fine. If your making mad cash off it, they might/will bust you.
Shitty times have hit Canadian seed sellers with attempts of American goverment trying to extradite sellers who deal to America. This sucks more for the seller then the buyer, and lessens the number of willing sellers. Canadian goverment hasnt laughed this case out of court (yet), and is probably being pressured into making a deal for US $$. European goverments (Holland/England) are not as easily pressured into these types of deals and have proven to be "right" with the relaxed views of cannabis.
