> if you have a clean bill of health, your mind is in the right place, no family history of severe mental illness, and have a trusted sober friend

And if you have all that you don't need to be doing mind altering drugs anymore.

I highly recommend trying mushrooms or acid for someone in a good place mentally who wants to improve themselves. Obviously one should do their own research for responsible consumption, and find a good set and setting.

I went from drinking a consistent 1-2 alcoholic drinks a day (very rarely getting drunk tho, just loved homebrewing and craft beer), being nearly obese, with little cardiovascular/muscular fitness to being in a much better place. I now exercise regularly, have a resting heart rate of 54 bpm, lost 30 pounds, meditate every day, eat much more healthfully, rarely consume alcohol, and I am more patient and listen to my partner better.

The increased neuroplasticity caused by physcadelics when combined with a desire to improve habits is a very powerful combination.

There is also a legal, mushroom based therapy for anxiety and depression that has shown great results, available in Oregon.

I really do believe society is much too welcoming of alcohol consumption, and much too resistant to physcadelics. We got this one so wrong.

I sense judgement from you towards anyone who has found utility or enlightenment through mind-altering drugs.

Just because I'm smart doesn't mean I stop reading. Just because I am fit doesn't mean I stop running. Just because I'm happy doesn't mean I can't dabble with new mental models.

And finally, to clarify the OP's statement: "Mind in the right place" doesn't mean being perfectly happy or without stressors/depression. To me it suggests someone doesn't have mental illness or suicidal tendencies.

You do if you want to "see for yourself". Which was GPs entire point.

I'm not saying psychedelics can't make you perceive things an unaltered brain cannot. I'm just saying they can't fit tens of thousands of times as much thought into the same amount of time, just that they can make you believe you did, and that experiencing a sense of deep time is not the same thing as experiencing deep time itself. I can dream or be drugged or hypnotized or otherwise fooled into believing I had sex with a supermodel. That doesn't mean I know what it's actually like.

Offer any real reason why a person cannot experience extreme time dilation? Proof by contradiction? Anything other than a hunch... Because a lot of people across a lot of cultures with various substances have experienced and independently reported this. To say "no because I don't think so" is akin to gas lighting people who dropped a ball and observed it always fell, or found certain ores were attracted to certain metals. There's a lot of evidence for these experiences, and it's quite reproducible.
