Make some weed cheesecake. Chicks go crazy for cheesecake. I'll type out the recipe if you're really interested.
Cover her room with buds. Weed buds, not rose buds. It'll be all romantic and then you can pee on her.
I love all of the serious ideas in this thread, but dude, what you already got in mind is perfect as is. I would be SO STOKED to get any of that stuff for Christmas. One of my favorite birthday presents was a pretty Bic lighter, lol.
A box of swishers (comes with 60 cigarillos), 1/8-1/4oz of the best weed you can find, and then treat her to a really fucking nice meal, regardless of if you have to drive into the middle of the largest metropolitan area around you. Stoners appreciate good eats.

He he. The VaporGenie is very good for pot, hash and extracts/concentrates, as well as chemicals. The only thing I know it is NOT good for is Salvia Divinorum. The only thing I have had no success vaporizing in it was 5-meo-MIPT, all the way up to 15 mgs.
