I'll maybe just jump in here.
I want to go back to what Mr. Scarpaleggia asked originally about methadone. This is just so we all get a little better understanding. We know that if someone comes in with a heroin addiction, methadone can help with some of the side effects of withdrawal and other things. You said that when people come in, they're given a medical. Is there a urinalysis? Is there a blood test? Why don't we know how many are addicted or how many have heroin in their bodies?
