You can't smoke the seeds, they explode on you. That's why they're legal. I don't know if they've got any of the chemical that makes you high in them, though.
Head shops proliferate down here, but if you have a record you can't even go into one. I was in one where they sold the little vials, coke spoons, even sifters for coke and crystal, as well as the bongs. I even found a used pot pipe once in my yard--cleaned it up and gave it to a friend (that tar is impossible to get out). Now I could've been arrest for possessing any of the above, except the little vials. I actually know people who use the little vials in perfume making and you know the little bags drugs are sold in? Those are also considered paraphenalia (sp?), but I also know people who use them for jewelry. If you're a teenager and you have several boxes of baggies (regular sandwich type) you can also get arrested for paraphenalia.
