Springboard sounds like another parasite on the system.  Their message should be:
* Inexperienced users (and newly licensed drivers) should not toke and drive
* Never mix drugs and drive

"Don Cooley, a programs manager at Springboard, said he often sees evidence of young people’s lack of knowledge about the drug on social media sites, among them that “the person who smokes pot is the designated driver at a party” and “the one drinking alcohol will smoke pot to sober up to drive home.”"

 “the person who smokes pot is the designated driver at a party”
Yes and oh so wise (even if the motivation is to beat the breathalyzer not to make good choices) 

 “the one drinking alcohol will smoke pot to sober up to drive home.”"
Balloony.  Well know equation:  P + A = S
Pot (stoned) plus alcohol (hammered)  equals stammered.  
And you'd fail the breathalyzer. Duh!
