A dutch weekly "Nieuwe Revue" (http://www.nieuwerevu.nl/) had a great idea this week. Included with their magazine (circulation 70.000) was a little bag containing 2 seeds for weed/grass and a manual how to grow it with the promise that if you followed the instructions you would have a stunning 250 grams of weed in june...
From what I´ve read on the dutch blogs was that everybody complained about crushed seeds. Yesterday the major supermarkets ordered their staff to remove the seeds from the magazine before putting them up for sale.
