The female of the species is well known for hiding what they think you may not like in order to get the attention of a male.
Leaving aside alcohol and cigarettes, there are other addictions that are disruptive and sometimes dangerous within relationships.
Meths use amongst females is perhaps more obvious but sugar and food addictions and prescription drugs perhaps less obvious.
