Researchers in Australia say evidence is weak as to whether medicinal cannabis treatments can help with mental illnesses such as anxiety, depression and psychosis.
医用大麻治疗是否有助于焦虑、抑郁、精神错乱等精神疾病？澳大利亚研究人员认为证据并不充分。

They add that doctors should be very careful when deciding to give the treatments to patients.
他们还表示，在决定对患者进行大麻治疗时，医生应该小心行事。

The researchers examined scientific studies on the effects of medicinal cannabinoids on six mental health disorders.
研究人员查看了医用大麻在六种精神疾病中所发挥作用的科学研究。

They found "a lack of evidence for their effectiveness."
他们发现，“没有足够证据能证明医用大麻的效果。”

Louisa Degenhardt is a drug and alcohol expert at Australia's University of New South Wales in Sydney.
路易莎·德根哈特是澳大利亚悉尼的新南威尔士州大学的药物和酒精专家。

She said her team's findings have important effects for countries such as the United States, Australia, Britain and Canada.
她表示，其团队的调查结果对美国、澳大利亚、英国和加拿大等国有重要影响。

In those countries, doctors are making medical cannabis available for patients with some kinds of illnesses.
在这些国家，医生会用医用大麻来治疗患有某些疾病的患者。

The study results appeared in the publication The Lancet Psychiatry.
这项研究结果发表在《柳叶刀·精神病学》期刊上。

Some military veterans and others who suffer post-traumatic stress disorder (PTSD), depression and anxiety
患有创伤后精神紧张性障碍（简称PTSD）、抑郁症和焦虑症的退伍军人和其他患者表示，

say cannabis is helpful in easing some of their symptoms.
大麻有助于缓解他们的部分症状。

Degenhardt told Reuters, "Cannabinoids are often advocated as a treatment for various mental health conditions.
德根哈特对路透社表示：“大麻素通常被视为各种精神健康疾病的治疗药物。

(But) clinicians and consumers need to be aware of the low quality and quantity of evidence..."
（但是）临床医师和消费者必须了解证据的质量很低，而且证据不足。”

Cannabis is also used for conditions such as nausea, epilepsy and traumatic brain injury.
大麻也被用于治疗恶心、癫痫、创伤性脑损伤等疾病。

The study did not examine its effects on those conditions.
这项研究并未调查大麻对这些疾病的作用。

Degenhardt's team wanted to look at all available evidence for all types of medicinal cannabinoids.
德根哈特的团队希望查看各种医用大麻的所有可得证据。

They investigated whether the substances stopped or lessened symptoms of depression, anxiety, attention-deficit hyperactivity disorder (ADHD), Tourette syndrome, PTSD and psychosis.
他们调查的内容为：大麻能否终止或减轻抑郁、焦虑、注意力缺陷多动障碍（简称ADHD）、妥瑞氏症、创伤后精神紧张性障碍和精神错乱等疾病的症状。

They examined 83 published and unpublished studies.
他们查看了83项已发表和未发表的研究。

The research covered about 3,000 people involved in studies between 1980 and 2018.
这项调查涵盖了大约3000人，这些人参与了1980年至2018年间进行的各项研究。

They found that medicinal cannabis made psychosis worse.
他们发现，医用大麻令精神错乱问题更加严重。

And it did not greatly affect any other major results for the mental illnesses studied.
至于研究涉及的其他精神疾病，医用大麻也未能对任何主要结果产生重大影响。

Tom Freeman is an addiction and mental health expert at Britain's Bath University. He was not involved with the study.
汤姆·弗里曼是英国巴斯大学的成瘾和精神健康专家。他并未参与这项研究。

But he said the findings show an important need for high-quality tests of medical cannabis to strengthen the evidence.
但他表示，研究结果表明，现在急需对医用大麻进行高质量测试，以强化证据。
