If you get busted, and the adjudication is withheld, how hard does that stick?

I'm asking because, I was just offered an internship in Tampa. And if I get it, I should be able to get grants to get into University of florida. Only problem is, I've read somewhere that a drug charge takes your chances of getting a grant to /nill Any truth to that from someone with experience?

Thanks,
