I suppose with prolonged, and extensive use or in any form of abuse, it can easily become physically and mentally addictive like anything else. But comparing Buspar to other drugs like opiates or amphetamines, I would say no, it is not addictive. However it will ultimately come down to the mindset you have with taking them. I would suggest being extra aware of your style and behavior towards using Buspar to determine if you are developing a habit or not. However when i used to take them, i dont recall any noticeable physical dependence with them
