Teen marijuana use not linked to later depression, lung cancer, other health problems, study finds. WASHINGTON -- Chronic marijuana use by teenage boys does not appear to be linked to later physical or mental health issues such as depression, psychotic symptoms or asthma, according to a study published by the American Psychological Association.
Researchers from the University of Pittsburgh Medical Center and Rutgers University tracked 408 males from adolescence into their mid-30s for the study, which was published in Psychology of Addictive Behaviors. "What we found was a little surprising," said lead researcher Jordan Bechtold, PhD, a psychology research fellow at the University of Pittsburgh Medical Center. "There were no differences in any of the mental or physical health outcomes that we measured regardless of the amount or frequency of marijuana used during adolescence.
" The research was an offshoot of the Pittsburgh Youth Study, which began tracking 14-year-old male Pittsburgh public school students in the late 1980s to analyze various health and social issues. Twitter. Gene therapy cures leukaemia in eight days - health - 26 March 2013. WITHIN just eight days of starting a novel gene therapy, David Aponte's "incurable" leukaemia had vanished.
For four other patients, the same happened within eight weeks, although one later died from a blood clot unrelated to the treatment, and another after relapsing. The cured trio, who were all previously diagnosed with usually fatal relapses of acute lymphoblastic leukaemia, have now been in remission for between 5 months and 2 years. Michel Sadelain of the Memorial Sloan-Kettering Cancer Center in New York, co-leader of the group that designed the trial, says that a second trial of 50 patients is being readied, and the team is looking into using the technique to treat other cancers. The key to the new therapy is identifying a molecule unique to the surface of cancer cells, then genetically engineering a patient's immune cells to attack it.
In acute lymphoblastic leukaemia, immune cells called B-cells become malignant. More From New Scientist Promoted Stories Recommended by. Mortality, Summary List of Causes - 84f0209x2008000-eng.pdf.
