There's some reckless recommendations to try psychedelics in here; be cautious with things classified under that name, because there are some VERY nasty chemicals getting pumped out by mafia chemists (some of whom work for large pharma corporations) and pushed under the name of relatively benign substances.

So first off, be sure you know what chemical is actually in the specific pill/blotter/tab you are considering eating.

Second, once you know what you're dealing with, understand the cautions and protocols involved in using that particular one. I won't start rattling them off, the information is out there.

That being said, a gram of mushrooms is safe for nearly everyone of normal adult physiology, and it's pretty easy to tell if you're looking at and gagging on mushrooms.

I was severely depressed at one point a couple decades ago and a chocolate containing a couple grams of mushrooms at a Folk Festival pulled me out of it for a good while and filled my head with thoughts of what was possible rather than what was not.

If you don't smoke weed, try smoking some weed, if it's safe to do where you are. It's more of a momentary thing and if you don't like it, most folks can handle waiting it out. This video is perfect for that situation, IMO. It can definitely be a heavy thing if you go too far too soon, but you'll come back fine with a story to tell, or to never tell.

The more general proposition, which is that these chemicals can kinda shake you loose mentally, is true, but whether that is a good or a bad thing depends on who you are, how in control and confident you feel about life and the world, your immediate environment when you are on them (many end up taking these drugs at noisy parties full of drunkards, which are not the best places to be tripping balls), and many other factors.

For instance, your talk of the adult mask vs the child you cannot find might be exactly what's happening, or it might be words you've put on some other mental block or bit of cognitive dissonance which you do not yourself understand yet. If that were the case, it would be quite possible for a dose of psychedelics to cause your mind to completely drop the veil of delusion, and cause you to look at that reality in the flash of a moment, with no time to mentally prepare for it, and that can be a terrifying experience for some, when reality intrudes on something that they didn't realize was foundational to their understand of the world, and vulnerable in that way.

The long term effects of such an experience can likewise be very good, very bad, or completely neutral. We all have these masses of jelly inside our skulls and actually we are those masses of jelly.
