No, there isn't a separate reservation category for "project affected certificate" in MPSC exams for Drug Inspector seats or any other health sciences exams  .

The MPSC follows reservation policies set by the Government of Maharashtra. These categories typically include Scheduled Castes (SC), Scheduled Tribes (ST), Other Backward Classes (OBC), Vimukta Jati (VJ), Nomadic Tribes (NT), and Persons with Disabilities (PWD). You can find detailed information about these categories and their reservation percentages on the official MPSC website

While there isn't a specific reservation category for project-affected people in MPSC exams, some government schemes might offer rehabilitation benefits or job quotas for people displaced due to government projects. However, these benefits wouldn't typically translate into reservations for competitive exams like MPSC.
