The study explored the immediate impact of internet exposure on the mood and psychological states of internet addicts and low internet-users. Internet addiction was associated with long-standing depression, impulsive nonconformity, and autism traits. High internet-users also showed a pronounced decrease in mood following internet use compared to the low internet-users. The immediate negative impact of exposure to the internet on the mood of internet addicts may contribute to increased usage by those individuals attempting to reduce their low mood by re-engaging rapidly in internet use.

This BMJ article calls for a shake-up to public health, to revitalise the discipline, place the needed emphasis on the commercial determinants of poor health and take the lead in a move away from 'an abeyance to the corporate bottom line', with suggestions for key areas in which organisational and paradigm shifts are needed.

The first in a series of papers commissioned by Addiction which attempt to estimate the problems of 'addiction' globally and in different geographical regions.

Such estimates are available, but there is a need to collate and evaluate these to arrive at the best available synthetic figures.
