So this is what Nature has come to? Following up on a study where people took Ketamine once and felt good for a while? Nobody was doubting that people could get high on Ketamine. Isolating the most intoxicating metabolite is a bit useful, but it really bothered me that &quot;studies&quot; looking at a single dose of Ketamine and labeling the rather short effect &quot;sustained&quot; get so much press.
