Yes, it’s possible to get kicked out of rehab for breaking major rules, especially if there are safety issues like violence, threats, contraband, or using drugs/alcohol on-site. Many programs do give warnings or try to work with you first, and relapse alone does not always mean automatic discharge. The exact policy depends on the facility, so the best move is to ask upfront about their rules, warning process, and whether they offer a chance to step back into treatment.
