A police officer in East Liverpool, Ohio, collapsed and was rushed to the hospital after he brushed fentanyl residue off his uniform, allowing the drug to enter his system through his hands. The officer had apparently encountered the opioid earlier in the day while making a drug bust.
"This is scary. He could have walked out of the building and left and he could have passed out while he was driving. You don't even know it's there on his clothes," East Liverpool Police Chief John Lane told CNN.

I think you have to consider biological half times too. In order to get the dosage comparison correct. I know that becomes hard math, but that's the way nature is shaped.
So a dose is delivered and the amount of active substance is then turned into half after x amount of time. Such that y amount of substance is active at a specific instance of time. If another dose is delivered then that is added on top of the first.
Morphine: half-life 2-3 h, bio-availability 20-40% (orally), 36-71% (rectally), 100% (IV/IM)
Fentanyl: half-life 10–20 min (T1/2 β) 2–4 h (T1/2 ɣ) Intranasal: 6.5 m Transdermal: 20–27 h Sublingual/buccal (single dose): 5.4–6.3 h, bio-availability 92% (transdermal) 89% (intranasal) 50% (buccal) 33% (ingestion)
Carfentanil: half-life 7.7 h, bio-availability --
LSD: half-life 3.6 h, bio-availability 71%
Potency:
Morphine: x1
Fentanyl: x100
Carfentanil: x10 000
LSD: Looking at minimum dose of 20 µg it seems on par with Fentanyl.
What is the reason to use LSD ? It can really mess up the mental state.
