The results suggest that an important contributor to the development of motivation for change is a perceived conflict between being an addict and holding other important and positively valued identities, or between being an addict and becoming the person one had hoped to become. Average scores on identity-related motivation for abstinence were higher in this sample than were comparable scores for motivation arising from social influence, health, and legal issues.

This phenomenon contrasts to the well-known observation that repeated drug administration can lead to many diminished responses (i.e., tolerance).

Moreover, not only is deviance a continuum – from “high consensus” deviance  (rape, murder, robbery) to “low consensus” deviance (stealing a newspaper, smoking  marijuana, getting drunk at a party) – and not only does censure vary from one social  circle to another, but homosexuality itself is a continuum with respect to degrees of  deviance. In the past generation, the abbreviation LGBT (sometimes rendered LGBTQ)  has come into being; it gained acceptance so quickly that, in many circles, hardly  anyone has to explain what it means. It refers to the variant sexuality or homosexuality  cluster: Lesbian, Gay, Bisexual, Transsexual (plus “Queer,” though the “Q” sometimes  means “Questioning”).
