Equate? Sure, they aren't equal. For instance I'd much rather be a passenger in a car with a driver who's had a regular, cup of coffee-sized dose of caffeine than with someone that's even had a little bit of LSD.

OTOH LSD seems to be non- or low- addictive but coffee will get you hooked and give you withdrawals.

They're all mind altering drugs. Each thing is different. Some find value in them that others don't.
