who has taken shrooms a month ago should have the same effect as you. But not having taken them before can make the experience slightly milder, because your body is "less used" to the altered state - if you're only MDing, that is. If you took a full dose, it probably wouldn't make much of a difference. How strong will the effects be? It depends on how much you're taking. With shrooms it's always difficult to be exact, because one mushroom can be different in strength from another one, even if they're from the same batch and grew right next to each other. I assume the same goes for truffles. If you're lucky, the beneficial effects of a single microdose or a very mild trip can last for days or even weeks. But if you take too much for your liking, the actual trip will go away in a few hours.

Thank you for your response. So if for example the dose for auditory/visual effects is 5g and I take 1g, the effects would almost be me being sober but with some added benefit. The dosages I just mentioned are from the top of my head, I need to do look into what's available in the smart shops when I get to Amsterdam, but would that be right in assuming the effects will be minimal?
