Sources tell CBS 3 that blood tests on the crane operator involved with Wednesday’s deadly building collapse in Center City detected the presence of a prescription painkiller and marijuana.

How much of either?

If he smoked marijuana and took the painkiller the night before last then what does it have to do with anything?

If he smoked the marijuana and took the painkiller in the last hour defiantly relevant.

I recalled a report on flying and marijuana. Seems that numerous studies show that up to 24 hours later, pot impairs the ability to perform tasks. But depending on the pain meds - they probably had a greater effect.
