How would you rank drugs, in order from tamest to “hardest”?

Personally, I’d order them thusly:

Life
Caffeine
Nicotine
Weed
Alcohol
Salvia
Psychedelics (shrooms before LSD)
Coke/crack
Meth
Benzos (this one’s tricky to place)
Opioids (least potent to most potent)

Maybe I’d put benzos higher up, perhaps at least before meth, I’m not sure.
I didn’t include all of them of course, just ones I’m more familiar with.
