Justice committee  I would be surprised at that.

Justice committee  Given the ability for alcohol molecules, which are extremely small, to disseminate into areas where there is no alcohol, the further you go back, the greater the chance of the alcohol dissipating. It would be surprising to me that you could get an accurate result further back tha

Justice committee  It would depend on the volume it's within. Alcohol will distribute or diffuse into the space where there's no.... It goes from an area of high concentration to an area of low concentration. It diffuses very rapidly. The larger the area for diffusion, the greater the chance of t

Justice committee  Almost immediately, if it's a strong sample. Let me back up. The higher the concentration of alcohol, the longer it takes for the fuel cell to actually process all of the alcohol. I don't propose to do what I'm going to do later tonight and lecture in the way that I'll be lec

Justice committee  I have two. That's correct.

Justice committee  Yes, they do. There are different ways to access the passive function, but they both can be used passively.

Justice committee  They both use fuel cell technology. Neither one of them is going to allow me to have the proprietary formula for their fuel cells, but they do both work on a fuel cell technology. They are both rapid in their response.

Justice committee  I hesitate to call it “a” device because there are multiple devices. I would support devices that use fuel cell technology. There are devices out there that use semiconductor technology, and the semiconductor technology tends to be a lot less.... It used to be, anyway; maybe it

Justice committee  At the risk of stepping on the toes of my colleagues from the drugs and driving committee, and since the chair doesn't sit that far from me in my lab and I'm very afraid of her, the answer is no. We don't have any viable technologies available of this nature. My colleagues on dr

Justice committee  The engineering challenges would be huge. The wide variety of chemistries and differences in drugs that can cause impairment make it almost impossible to have anything that will detect passively those types of drugs. What you would have to have is about a million-dollar mass spe

Justice committee  I absolutely agree that it's possible for devices to detect passive alcohol.

Justice committee  Yes, it can be. As I indicated earlier in my testimony, it is a useful tool as long as how they're doing it is properly controlled. There are a lot of variables involved, and I think they have to be very on point with the way they're performing this type of analysis for it to m

Justice committee  As I said in my testimony, there's no doubt that passive detection has been used and that it can be useful in detecting alcohol-impaired drivers.

Justice committee  Asking a scientist if something is worth studying is sort of like giving candy to a baby.

Justice committee  We always want to study things, but whether we have the time and resources to do it is where we have issues. Certainly we have very curious minds on my committee.
