I'm a developer, and I have an app, but its main focus is weed. Marijuana is illegal in my state (NY, U.S.) The app does nothing illegal, it's closer to a database app, but the database centers around marijuana.

Is there any problem putting something like this on my resume or in my portfolio? If the work is good, will the content have a negative effect on employers? Can employers reject me from a job based on a project like this?
