As someone who has spent a few weeks microdosing, the effects of LSD are definitely not a placebo effect, BUT! Psychedelics are not fire-and-forget like SSRIs, Adderall, or any other substance class known to the masses. Psychedelics bring up your subconscious processes into aware consciousness, and do so to lesser extent even at microdoses. What you actually do with this and use it for, is also precisely what will define the utility and benfit (or harm) for yourself. The effects and the benefits you can get off microdosing depend on the same things on which the outcome of real full-dose trips depend: Set and setting.

Dosing acid every morning will do absolutely nil for you if you're just going to continue doing what you always did. You're going to do it with a little bit of an expanded mind, have comparably better creative and abstract thought streams, maybe get to see small glimpses of how your subconscious works during your daytime routine, and appreciate details and life itself more. You might also start interpreting too much into your experience or experience placebo effects.

Nothing of that is permanent, and nothing will change, until you actually start to use it with clear intent as a tool to accelerate forming of new habits and thought patterns for yourself, which is MUCH harder than it sounds like. What LSD is really good at is opening up the flood barriers of your subconscious mind and removing filters off your perception, which then leads to exactly the effects you can use for benefit - that every experience you make while under the influence is immediately ingrained into your neural pathways 100x stronger than usually, and your stream of thought and inner monologue is very.. "clear" and accessible, so you can also apply this effect to your own inner unconscious monologue. This is for example where trauma is continued within yourself. You might have noticed that, if you let your mind chat and run unchecked and unwatched, sometimes it will start to form thoughts and inner monologue that resembles closely how you were treated by your parents in early childhood.

Coupled with downsides of microdosing (and yes, there are downsides), it is a really delicate venture to undertake and you will need good knowledge and experience of psychedelics, psychology and a clear and direct intent, plan and motivation, or you are bound to end up just routinely microdosing for no purpose whatsoever and fuck up your brain chemistry for a while.

Would recommend to some, but definitely not as a routine activity. Max 1 week.
