Is melatonin habit forming or addictive?

Melatonin doesn't cause withdrawal or symptoms of dependence, unlike other sleep medications. It also doesn't cause a sleep “hangover,” and you don't build up a tolerance to it. In other words, it doesn't cause you to need more and more as time goes on, which is a hallmark of addiction.
