Mr. Speaker, that is a very good question, because the technology is there to detect what is in the system. The issue is whether the person was impaired, and it depends. In fact, I think the example has been given that marijuana can be detected in the blood system for four weeks, but the impairment may only last for hours, so it is not just a matter of whether or not it is there.
As for the evidence that the technology is available, we can just simply to look at what has been done in terms of the drug testing that now is done for the Olympics and for professional athletes, et cetera. The detection is there now, but there has to be the linkage to impairment. That is why we need the training for the DREs: for them to be able to detect the signs and to get the proper information and observations down so that their expert testimony and the results of drug testing will in concert indicate that likelihood, along with other evidence they may have.
I am not at this point sure, but this is one of the reasons why we have a committee to look at a bill after we get a chance here, before we have heard any of the current testimony of witnesses and experts in the fields and disciplines that are relevant to this bill. It is important that this bill get to committee. It is important to hear questions such as the one the member just posed, extremely important, in order to make absolutely sure that we understand the tools being proposed under this bill in fact are going to be effective and are indeed going to be properly funded all across the country.
