Secondhand Smoke Linked to Mental Distress


Risk of psychological troubles rises for exposed nonsmokers

From Science News
By Bruce Bower

Where there’s secondhand cigarette smoke, there’s emotional fire. As exposure to cigarette fumes increases among nonsmokers, so does their risk of developing serious psychological distress and of being hospitalized for mental ailments, a new study finds.

Cigarette smokers have been shown to have more psychological problems than nonsmokers do, and new evidence suggests that nonsmokers who inhale high levels of secondhand smoke may experience nearly as much psychological distress as smokers, say epidemiologist Mark Hamer of University College London and his colleagues. Overall, these findings support the view, largely based on animal studies, that nicotine administered in large enough doses can induce sadness and other negative moods, the researchers propose in the August Archives of General Psychiatry.

“Our data are preliminary, but there is a strong possibility that the observed association reflects a causal link,” Hamer says.

Previous research suggests that nicotine alters mood by disrupting immune responses, stress-hormone regulation and the transmission of dopamine, a chemical messenger in the brain. But little is known about nicotine’s possible relationship to specific psychiatric disorders.

Homosexuality and Mental Health Problems


From the National Association for Research & Therapy of Homosexuality
By N. E. Whitehead, Ph.D.

Summary: Recent studies show homosexuals have a substantially greater risk of suffering from a psychiatric problems than do heterosexuals. We see higher rates of suicide, depression, bulimia, antisocial personality disorder, and substance abuse. This paper highlights some new and significant considerations that reflect on the question of those mental illnesses and on their possible sources.

The American Psychiatric Association removed homosexuality from its diagnostic list of mental disorders in 1973, despite substantial protest (see Socarides, 1995). The A.P.A. was strongly motivated by the desire to reduce the effects of social oppression. However, one effect of the A.P.A.'s action was to add psychiatric authority to gay activists' insistence that homosexuals as a group are as healthy as heterosexuals. This has discouraged publication of research that suggests there may, in fact, be psychiatric problems associated with homosexuality.
