Unfortunately, relapse is a symptom of this disease. Understand, though, it does not have to be a part of recovery or treatment, but it happens. Daylight Recovery loves the suffering addict! If a person is forthcoming and is still motivated for treatment or recovery Daylight Recovery generally desires to continue serving them... (Afterall: the Dr doesn't stop treating the diabetic who stops taking her insulin and eats a bunch of candy bars, does he?)
However, relapse generally comes with consequences. These can include: pauses in treatment, referral to detox, extended treatment, reports to court (for consented, legally involved patients), additional assignments, repeated classes, etc. Sometimes relapse (especially repeated) results in termination/suspension of treatment services. We generally welcome back, even these cases, after a period of time.
