Will I be taken seriously in college if I advocate medical marijuana, or will people just think im a pot head?

I am 100% for access to good marijuana for people that are sick and could benefit from this nontoxic, healing herb. However I do not advocate recreational use. I am going to be a freshman in college next year and what to join the Students for Sensible Drug Policy organization at my school and use that as my basis to help make people more aware of the benefits of medical marijuana. I do not smoke recreationally, nor will I, but I am scared that I will be automatically be thought of as a pothead by people. What do you guys think?
