Congrats on being white, it really has no bearing. This is 2004 the last I saw. This job is about integrity. When you are offered a joint, you have to do the right thing. If you are smoking weed, you are breaking the law. Plain and simple. Now what dept is going to want to hire someone who knowingly breaks the law? It may not be a big deal to you, but 99.99% of depts will find out about it and they will not hire you. Remember, you are not the only person applying for a job. Check out the PD's websites and see what their policies are. You might have a snowballs chance.
My wife left me alone with a case of Corona, a bag of limes and the cat. Beer is gone. What will I do with the extra limes and the cat?
