In this study, they measure the effect of Qigong meditation, a blend of relaxation, breathing, guided imagery, inward attention, and mindfulness, on addiction recovery. Those who chose to participate in the meditation showed a treatment completion rate of 92% versus 78%  (p < 01) and reported a reduction in craving, anxiety, and withdrawal symptoms, although it was dependent on the quality they approached the meditation with. While all in the meditation group reported reduced anxiety, the female participants reported significantly more reduction in anxiety and withdrawal symptoms than their male counterparts. Overall this shows positive evidence for the integration of meditation into established addiction recovery procedures.
