If you use during treatment, it’s usually treated as a relapse, and most programs won’t kick you out right away—they’ll work with you to get back on track. Depending on the facility, you might face more frequent drug testing, extra counseling sessions, or a step-down to a different program level. Relapse is common in recovery (40-60% rate), so the key is being honest with your team to adjust your plan and avoid bigger issues.
