Drug addiction affects men and women in roughly equal numbers. However, the circumstances surrounding addiction rates between the genders are far more nuanced. As such, male-only or female-only treatment centers might be the best option for patients. Abuse and addiction treatment programs, however, are most effective when tailored to the patient’s specific needs and circumstances. Attending either a mixed-gender rehab center or female or male-only center is ultimately up to the patient and their medical team.
