LSD for me personally brings out the most of my childlike self. Hell, when I took too much and thought I was dying, and hallucinated that I had died, I realised that the last thought I had before I "died" (Was all of existence real, or was it a dream/illusion/fantasy?) is the EXACT thing that shaped my entire childhood, and my entire personality. I was, and am, autistic and I used lie awake at nights wondering about the nature of existence, consciousness, biological life. The most frightening question I had, was that maybe it was possible that the universe was my own fantasy, not in a megalomanic way, but more like I could have been some alien having a very elaborate dream. Understanding that mindfuck and how it affected my perception of reality, my social interactions (nobody around me understanding my questions, leading to isolation and realisation) changed my life and it's now the keystone around which I organise my mind and life.
But, it needs to happen in a good setting, a good environment, with few disturbances and a good guide. In my case I was experienced enough that I could guide myself and didn't freak out and call a fucking ambulance or some shit, but if you do it by yourself and you don't know what's going on, if you do it in the company of others who don't know what's going on, it can get incredibly fucked up.
Cannabis will promote similar mindstates, while psychedelics can broadly bring back your "childlike building blocks" of your mind, cannabis does the same but very selectively for specific elements of your childhood, depending on your high, but it may seem very "druggy" to you if you've never taken psychedelics. If you have used psychedelics, you will be able to recognise the psychedelic components.
