It's certainly ok in that respect, but if they're half decent mushrooms 4g is gonna rock your fucking world.
To me "eating an eighth" (3.5g) is the full-blown experience with mushrooms, one that I don't care to experience very often and haven't in many years. Pretty life-changing for me.
I find mushrooms to be very intense mentally, even at low doses. This is exacerbated by the lethargy and body load as you can find yourself couch locked, deep in your head and introverted (for better or for worse). IME Tryptamines can lend themselves to more frightening (albeit impressive and beautiful) visuals than other other psychedelics. They're very organic and even humanoid at times.
If you do take 4g, I'd definitely get out in nature with lots of daylight. Not a psych I wanna get caught stuck on indoors, at night, or both.
