And no there's plenty of anecdotal evidence from long term users who never feel the same after frequent use, even after stopping. But again by your logical reasoning because there's no peer reviewed study on humans that sufficiently backs this up people should ignore that.

People who use one drug often use others, and often concurrently. We use science to disentangle these confounders like this.
I have no problem with people advising caution in using powerful drugs, and advising against them fully if they have a family history of mental health issues. I do have a problem when people try to use flawed science to give this caution a false sense of authority.
Aging is a thing. Most adults don’t “feel the same” after the passage of a “long term” span of time, regardless of their level of substance use.
