This is what any major dude was saying he was too lazy to get: receptor affinities for LSD. The
low bars are the one's it has a high affinity for, and bars above the horizontal line mean that receptor is unlikely to be affected substantially and typical recreational doses of LSD (notice all the serotonin receptor subtypes it has little or insubstantial affinity for):
What other psychedelics have you used and do you have the same MDMA like subjective reaction? It sounds like you have little or no experience with psychedelics outside of LSD. The fact that it feels so good for you most likely owes to some
chance fortunate distribution of receptors that support euphoria in your brain that LSD's receptor binding profile just happens to map onto. So, congrats, you're lucky (if euphoria is what you're after), but it isn't that way for everyone (maybe for them it's 2C-E) -- and even though it might feel good to tell yourself others don't get the same reaction as you because they are weak of mind and therefore you are strong, your experience with psychedelics seems far too limited to make those kinds of conclusions. I'm not sure you can ever make those kinds of conclusions based on reactions to psychedelics; having a great time consistently with a wide variety of challenging drugs across time and varied circumstances is
more indicative of this, but still far from guaranteeing a person's resistance to all or even most of the vast variety of psychologically challenging phenomena we are likely to encounter in life; there is no single litmus test for a strong mind.
In fact, this kind of conveniently ego-boosting single litmus test simplification is extremely common, especially among young male psychedelic novices with a short string of good trips behind them. They assume they must have some mental power they exert over the psychedelic to account for their reaction instead of assuming far more likely chance related factors. This interpretation allows them to take personal responsibility for their joy (which makes them feel even better!). Don't take that as an insult, it's simply an affirmation of your normalcy; we all delude ourselves in various ways to feel special (strong self delusion, within reason, is actually considered psychologically healthy). I'm not saying that you're definitely not especially strong of mind, just that a few LSD experiences do not make for a reliable metric of such things, and that the conclusions you've reached are well within a few standard deviations of the average young psychedelic explorer's.
