While you could say a drug is "LSD-like" because one of the many receptors it targets is also targeted by LSD, that would be more akin to saying a keyboard is "hard-drive-like" because they both plug into a computer.

Biology is extremely complex, and even drugs that have similar receptor binding profiles can have very different effects.

Most drugs will have action across a wide range of receptors. There are a multitude of drugs that target the 5-HT2A receptor, including the most common antidepressants and antipsychotics, for example.

Hmm, depends on the receptor, where the molecule or the hard drive docks to?

So USB hard drives might be keyboard like (for USB keyboards), but hard drives which dock to the SATA connector aren't …

Anyway, such comparisons sometimes limp and sometimes don't have any legs at all.
