A phase 1 clinical trial has tested the use of psilocybin to treat anorexia nervosa. Ten women with the disorder were given 25 milligrams of the hallucinogen along with psychological support.

Four patients showed an improvement, but the authors acknowledge that, because of the small sample size and the absence of a control group, "the results are preliminary and further research is needed". The results are published in the journal Nature Medicine.

Beta-blockers (β-blockers) are drugs to treat heart conditions that are also used for anxiety. According to research published in PLOS Medicine, periods of treatment with these drugs are associated with a lower risk of being charged by the police with a violent crime - a 13% lower risk than periods without treatment. The research, which included nearly 1.5 million people in Sweden between 2006 and 2013, does not support the use of these drugs to treat anxiety.
