Hey man.
the advice i can give you is how i think you should go about your business.
first, you should try to get a B or higher at least in high school. this will open up your college choices. throughout high school, you should try to learn about tobacco growing, curing, etc, and how to roll a good cigarette.
next, you need to find a undergraduate college with a good business program, and major in business management. a few good colleges for this include Florida State, Boston College, university of las vegas, and others. along with your studies, you should spend alot of your time in college seeing the trends of tobacco companies, becuase as of now, they appear to be losing their popularity. you should try to make a cigarette that stands out from the others in some way, as a way to market your product. This includes maybe an attractive slogan, a unique style of cigarette, maybe a different additive that changes taste (the guy who thought of putting menthol in cigarettes made a forturne).
when you finish college, and have a good idea of the mix and style of your cigarette, you can begin finding stores around your area that are interested in promoting a new brand. Large chains, like 7-11, are not a good place to begin, because they will want enough cigarettes to stock all their stores nationwide. maybe an independent local chain will do.
while your products are being sold, or even if sales aren't so good, look into getting your MBA from a business school. the colleges mentioned above also usually have good business schools attached to them. the classes you get to get your degree will teach you how to better manage a company in areas including budget, employee management, advertising, etc.
if the cigarettes you have made become regionally popular, you may think of expanding your farm to a plantation size, and higher farmers to harvest tobacco for you, and attempt selling your cigarettes to a large chain like 7-11 or AM/PM. and from there, the sky is the limit
i believe in you and your friend, and i find it very inspiring that at such a young age, students of your generation are making big plans for the future. good luck, and i hope and believe that you can succeed.
