Honestly i dont want to call anyone who has researched this stuff more than me, or is a doctor or scientist, an idiot.
But from what ive researched that is bullshit.
From what ive read, as your brain gets more suseptable to getting in a nuero-focus faster, your mind will transition to an altered state faster over time, allowing more mental,meditational, state to set in faster. thus your mind relaxes and your consious awarness stops fighting abnormal states, and trances.
All this meaning the more you are exposed to a specific freaquence, your mind is usually able to work with it, and allows itself to be influenced by it.
But diffrent doses run on diffrent frequencies, so while you may get good at one dose, dosnt mean you can do lsd for the first time and be able to get the full affect, or even have it work. You would have to get your mind able to settle with that frequency.
Some doses run on a similar frequency as others, and you may notice your able to get that dose to work as well as another. All becuase your mind used to that freaquency.
I kinda went farther into this then what you were asking, but its really a big linking story, that to understand one thing you have to understand everything.
I could be wrong, because im not the proffesional. But whatever.
