One thing I would not do is let them put my face and name all over the media! I would buy houses all over the US, and the world. Buy my family houses and cars. I would open up medical marijuana dispensaries all over California, and have a team of really good lawyers to get my back.
Then I would hire some badass artists to work on my comic.
I would go on a world tour with my wife, then settle down and have kids.
I would also run for office probably on the Green Party ticket. Also work to get federal drug laws repealed.
I would also produce a pro-marijuana propaganda movie. It would be to medical marijuana patients what Philadelphia was for gay people. We need to change our image, and change the national zeitgeist toward marijuana.
Sometimes I think movies like Half-Baked, and the Cheech and Chong movies, though funny can be bad for the movement. "Mainstream" American society looks at potheads as criminals, idiots, hippies, losers, drug addicts and slackers. I would like to produce a big-budget movie about a medical marijuana user (someone that has MS) that is using it illegally, and then gets busted, and thrown in jail. It could be based on a true story. Sorry tangent.
I would invest in silver, gold, and land. I would invest a little in stock markets.
I also would get a really good tax lawyer, and stop paying the IRS, because there is now law that says we have to pay federal income tax, and I'm sick of it!
