Arrests do not follow you around if you do just a little effort to legally fight it. Until you are convicted you are innocent, you just need to follow the process to ensure that you are never listed as guilty by no contest (which is sadly often the default if you don't ask for a court hearing).

I wouldn't expect a drug addict to know the above, but it still needs to be stated. If anyone happens to be arrested in the US make sure you don't accidentally get listed as guilty and served time (that night in jail counts as time served so if the judge would sentence you to one night in jail)
