It’s not just psychedelics, most drugs of *all* kinds are complex molecules. For example, penicillin’s molecular formula is C16H18N2O4S. Our body chemistry is incredibly complex. There are many thousands of various proteins, enzymes, and other chemicals interacting with each other to do the things that make us alive. The reason drugs work is that they interact with, alter, or mimic these chemicals in some way.

Think about combinations for locks. If you have 15,000 locks, and only want 1 combination to open 1 lock and none others, a simple 3 or 4 digit combination isn’t going to be enough because you’ll run out of combinations. Some will be simple, like “3” or “65”, but you’ll also wind up with longer combinations like “2954” and “14693”. You need complex combinations to open complex locks.

No of course this doesn’t mean *all* the combinations will have to be complex. some locks will open with a single or double digit combination. Going back to drugs, nitrous oxide is a commonly used anesthetic, and its molecular formula is just N2O.
