The Hardcore Ghost: The Return(1991)

Supernatural forces are once again at work to help a mortal out of trouble. This time it's about warehouse worker Mitch. The mafia is planting drugs in the warehouse without his knowledge. When a package goes missing, trouble starts. Since Mitch didn't know the package existed, he has no idea how to get it back. Then the HARD-CORE GHOST appears! Of course, the road to solving the case is once again paved with willing female bodies and lots of lively sex.
