Will a drug arrest from 20 years ago affect getting a liquor license in Illinois?

The real question should be: Were you convicted? Being arrested is one thing, going to court and being tried and convicted is something else. If you were convicted and have not been granted a Pardon, you will most likely be denied that licence, as a felon. Apply for a pardon, as soon as you can. Pardon may not have been the right word. In Illinios, if you are convicted of a felony, you will not be allowed to get a liquor license, period. Even if you go through the long, teadious task of trying to be "granted you rights" (ie. right to vote, right to bear arms), you will not be granted a liquor license. Take care.
