I'd blow it all on crack cocaine.
Just kidding.
I would do a lot of things. Open a B&M in as many states as possible. I'd lobby FOR flavored tobacco. Build a recording studio, go to school for music production. Buy a golf course. Buy a movie theatre. Build a house that has a movie theater and a recording studio in it. Pay Rad Davis to teach me how to carve pipes. Carve pipes in my newly built wood shop. Fight back against corrupt politicians in all corners of the world. Grow a lot of pot. Open some dispensaries. Umm... breed dogs. Develop an interest in Polo and other things rich people like. Hm... I'd buy some monkeys, too, and teach them how to smoke pipes.
Samcoffeeman, I actually read your post after I wrote mine, but I see that we have some similar ideas.
