To examine predictors of quitting behaviours among adult smokers in China, in light of existing knowledge from previous research in four western countries and two southeast Asian countries. ⋯ Predictors of Chinese smokers' quitting behaviours are somewhat different to those found in previous research from other countries. Nicotine dependence and self-efficacy seem to be more important for attempts than for staying quit in China, and quitting intentions are related to both attempts and staying quit.

Many cities have banned indoor smoking in public places. Thus, an updated recommendation for a breath carbon monoxide (CO) cut-off is needed that optimally determines smoking status. We evaluated and compared the performance of breath CO and semiquantitative cotinine immunoassay test strips (urine and saliva NicAlert®) alone and in combination. ⋯ In surveys of smokers and non-smokers in areas with strong smoke-free laws, the breath carbon monoxide cut-off that discriminates most effectively appears to be ≥5 p.p.m. rather than the ≥10 p.p.m. cut-off often used. These findings may not generalize to clinical trials, regions with different carbon monoxide pollution levels or areas with less stringent smoke-free laws.

Oxycodone is a major public health problem for many countries. The focus to date, however, has been on illicit drug users. Many (perhaps the majority) who are dependent on oxycodone, however, have never used illicit drugs. These people have been forgotten in public health interventions, and require urgent attention.

As preparations for the fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM) are under way, this paper focuses upon changes proposed for the substance use disorders section. It briefly outlines the history behind the current nomenclature, and the selection of the term 'dependence' over 'addiction' in earlier versions of the DSM. The term 'dependence', while used in past decades to refer to uncontrolled drug-seeking behavior, has an alternative meaning--the physiological adaptation that occurs when medications acting on the central nervous system are ingested with rebound when the medication is abruptly discontinued. ⋯ The criteria for the disorders are likely to remain similar, with the exception of removal of the 'committing illegal acts' criterion and addition of a 'craving' criterion. The other major change relates to the elimination of the abuse/dependence dichotomy, given the lack of data supporting an intermediate stage. These changes are anticipated to improve clarification and diagnosis and treatment of substance use and related disorders.
