We had some training (I'm a paramedic) about our death with dignity legislation: What to do if someone else has taken the drug cocktail (messy but if found soon enough we can usually take care of them)... .. what if someone has taken it and "changed their mind" or "it hasn't worked". In the former, we typically get the professionals who were involved there - is it a case of being (understandably) scared about what will happen, versus ... ? The other is that in some people the cocktail can take an extended time to work - 24, 48 hours. Forgive the black humor, but what does that 911 call look like? "I'm not dead and I'm meant to be, I took my cocktail of death-with-dignity meds and I'm still here."
