You can be charged with the possession crime.
The issue is whether the cops got the evidence in a legal way. You are saying they didn't. It sounds like there might be an issue there. If the cops did not get the evidence in a legal way, the paraphernalia is usually suppressed and the State will usually dismiss because they don't have any way to prove their case against you. The way to challenge the stop/search is a "motion to suppress".
