What happens if drugs were found in my car or home but they weren’t mine?

This is a constructive possession situation — the prosecution must prove not only that drugs were present but that you knew about them and had dominion and control over them. When drugs are found in a shared space such as a car with multiple occupants or a residence with multiple residents, establishing possession beyond a reasonable doubt can be difficult for the prosecution. An experienced attorney can effectively challenge constructive possession arguments when the facts support it.
