There is a high smoking rate among male psychiatric nurses in Jordan and among psychiatric patients in general. Smoking addiction inhibits nurses from helping patients with smoking cessation. A better understanding of the smoking behaviors of male Jordanian psychiatric nurses is required if they help patients with smoking reduction and smoking cessation. This article reports the findings from a classical grounded theory study that explains why male Jordanian psychiatric nurses are not ready for a smoking cessation role. Analysis of the statements made by eight Jordanian psychiatric nurses during individual interviews identified the last phase in a psychosocial theory of the smoking trajectory of the smoking behaviors of these nurses, the contextualizing smoking behaviors over time theory. This phase explains eight categories describe the challenges involved in quitting. We conclude that local contextual challenges to quitting need to be understood if smoking reduction and cessation programs are to be effective.
