Primary deviance can be converted into secondary deviance when the occasional users are to be labeled as ‘d o p e heads’, it is because a primary deviance is the stage where deviant behavior is in the initial stage whereas secondary deviance is where an individual is to be labeled as a criminal.
If an occasional user who does not always commit to a certain behavior and was labeled as a d o p e head of which is defined as doing things that are lowest to the low, they are to be called as a criminal of which falls at the secondary deviance.
