[ti:Medicinal Cannabis Not Proven in Mental Health] [by:www.knnrug.live] [00:00.00]更多聽力請訪問51VOA.COM [00:00.04]Researchers in Australia say evidence is weak as to whether medicinal cannabis treatments [00:07.22]can help with mental illnesses such as anxiety, depression and psychosis. [00:15.52]They add that doctors should be very careful when deciding to give the treatments to patients. [00:24.84]The researchers examined scientific studies [00:28.63]on the effects of medicinal cannabinoids on six mental health disorders. [00:35.76]They found "a lack of evidence for their effectiveness." [00:41.56]Louisa Degenhardt is a drug and alcohol expert at Australia's University of New South Wales in Sydney. [00:51.48]She said her team's findings have important effects for countries [00:57.29]such as the United States, Australia, Britain and Canada. [01:04.32]In those countries, doctors are making medical cannabis available for patients with some kinds of illnesses. [01:13.24]The study results appeared in the publication The Lancet Psychiatry. [01:20.80]Some military veterans and others who suffer post-traumatic stress disorder (PTSD), [01:27.06]depression and anxiety say cannabis is helpful in easing some of their symptoms. [01:36.16]Degenhardt told Reuters, "Cannabinoids are often advocated as a treatment [01:42.35]for various mental health conditions. [01:45.26](But) clinicians and consumers need to be aware of the low quality and quantity of evidence..." [01:55.24]Cannabis is also used for conditions such as nausea, epilepsy and traumatic brain injury. [02:05.56]The study did not examine its effects on those conditions. [02:12.12]Degenhardt's team wanted to look at all available evidence for all types of medicinal cannabinoids. [02:21.16]They investigated whether the substances stopped or lessened symptoms of depression, [02:27.92]anxiety, attention-deficit hyperactivity disorder (ADHD), Tourette syndrome, PTSD and psychosis. [02:38.70]They examined 83 published and unpublished studies. [02:45.12]The research covered about 3,000 people involved in studies between 1980 and 2018. [02:55.44]They found that medicinal cannabis made psychosis worse. [03:01.32]And it did not greatly affect any other major results for the mental illnesses studied. [03:09.96]Tom Freeman is an addiction and mental health expert at Britain's Bath University. [03:18.12]He was not involved with the study. [03:21.45]But he said the findings show an important need [03:25.65]for high-quality tests of medical cannabis to strengthen the evidence. [03:32.01]I'm Jonathan Evans. 更多聽力請訪問51VOA.COM 11运夺金走势图遗漏
