Vidyya Medical News Service For 01-February-2001:

The following stories appear in full on today's Vidyya Medical News Service Web site.

For African American teens who smoke, culturally-appropriate evaluation of nicotine dependence is an important part of cessation treatment, according to a study published in the December 2000 issue of the Journal of the National Medical Association. African American students continue to have the lowest rates of smoking among the nation's 8th, 10th, and 12th graders, however, extensive research also demonstrates the disproportionate effects of tobacco use among African Americans, such as smoking-related coronary heart disease, stroke, and lung cancer.

Researchers have demonstrated that television public service announcements (PSAs) designed for and targeted to specific teen personality-types can significantly reduce their marijuana use. In a study published in the February 2001 issue of the American Journal of Public Health, researchers report that PSAs with an anti-marijuana use message resulted in at least a 26.7 percent drop in the use of that drug among the targeted teen population.

Continuing this issue's focus on the subject of addiction, an interesting study in the July 2000 issue of the Journal of Immunology claims that tetrahydrocannabinol (THC), the major psychoactive component of marijuana, can promote tumor growth by impairing the body's anti-tumor immunity system. While previous research has shown that THC can lower resistance to both bacterial and viral infections, this was the first time that its possible tumor-promoting activity had been reported.

And now the good news...The 2000 survey of drug use among 8th, 10th, and 12th graders found that illicit drug use, including the use of marijuana, generally remained unchanged in the last year. The survey marks the fourth year in a row that the use of any illicit drugs among teenagers has stayed level or declined in all categories: lifetime, past year and past month use. The survey also found that cigarette use among teens dropped significantly.
