This is where your past addictions no longer take up much place in your thoughts and in your life at all. You consider yourself at no greater risk than anyone else to use. Congratulations. You have recovered and graduated recovery (AKA the maintenance stage)!
Remember, never lose your vigilance, and you are always still welcome at SMART meetings.
A good analogy to use with those who disagree with you, is would they call someone who stopped smoking 7 years ago a smoker?
People will generally reach this stage after 2 - 4 years of mostly continuous abstinence. Only you will know.
