I come to quite similar conclusions while tripping. Even if that's not a fill blown psychedelic but just a more intense weed experience.

Whenever the substance puts me into present I feel joy and peace. I usually go out of the experience with thoughts along "do more of it, regardles of this is drug induced or just mindfulness induced try to enjoy life more, hear the silence around you, stare at trees, live slower, do what's meaningful for you and don't spend so much energy on your corpo job".

Now, it all sounds like a great advice BUT I am incapable of becoming this person while sober, I just can't. My anxiety disorder and being quite a stressed person altogether prevents me from living like this while sober. So naturally my mind responds with "alright, so take those substances more frequently, it is good for you. Each time such thought appears however it is followed by a question: "oh, is it good for me? Isn't it exactly how people get addicted to substances? Isn't it just a trick?"
