They typically mark great achievements in sobriety and recovery, as well as mark the amount of time an individual has remained sober. The white chip, for example, is given for 24 hours/1 day of sobriety. The significance of this chip is to show the first day into recovery, and to give hope for continued success and sobriety. The white chip also has meaning for those who have relapsed, signifying the first day of returning to sobriety.
