Clinical onset

Clinical onset is when the the diagnostic criteria can first be said (by a medical practitioner) to have been fulfulled. It will not be when the substance was first used.

Clinical worsening

Evidence of worsening of the condition may be shown by an increase in the number of symptoms/diagnostic criteria or a more severe pattern of symptoms or problems resulting from substance use.  Establishing that any worsening represents a permanent clincial worsening will be more difficult, as there may be fluctuations in the pattern of substance use over time.
