The paper includes a caveat at the end: "Our study has several limitations. First, although the trial was formally double-blinded, assignment to placebo or LSD was unavoidably unblinded by the obvious psychedelic effects caused by the dose used."

Yea, I'd love to see the placebo group. "Nope... still in this universe..."

In some studies they use other drugs that illicit similar but different feelings, e.g ecstasy

FYI, the correct spelling is "elicit". "Illicit" means forbidden or illegal, ironically in this context.

Haha whoops. Thank you for that!

"similar but different feelings" - it can only be one or the other...

They are similar but different. They both are a departure from being sober. I think in one study about ecstasy they used an amphetamine as the placebo, because both get you wired but in different ways.

They are nowhere near similar in any capacity. It's like claiming that smoking and drinking produce similar effects
