This is especially dangerous for cannabis users because THC remains in one's system long after use. Smoke a joint the day before and find yourself involved in a collision where someone is injured - the coppers are taking your blood whether you like it or not and you are fucked.
Will the blood test determine recent cannabis use?Sorry but you're wrong about this. THC will remain in your system for days after use but not in your bloodstream. 90% of THC will be gone from the bloodstream within 6-8 hours after ingesting it. 24 hours after ingesting it there will be small traces in your bloodstream but not enough for intoxication. Blood tests are very accurate in determining someones intoxication level at the time of the test and thats why they use them. If THC, alcohol, or any other drug is in your blood then you are intoxicated by it, once its out of your bloodstream (and stored in your fatty tissues) you are no longer high. Urine tests will show THC for days and sometimes weeks after ingesting but not blood tests.
I did a lot of research on this after someone I know was involved in a fatal accident (in the state I live blood tests are required if there is a fatality), she smoked the night before about 1AM and the accident happened about 9AM the next day and they took blood. The blood test showed negative intoxication.

Because that was my point. I said nothing of intoxication which is why I used the one day example - plenty of time between smoking and safe driving.
I am concerned with the authorities invading my privacy on the pretext of public safety and learning things about me that have no connection with probable cause.
Then we'll just chalk this up to a difference of opinion because I have a major problem with any end run around our Constitutional protections.I do believe it can show very low levels of THC days after but from what I understand the levels are so low it is below the levels they are testing for or falls within a margin of error. The person I was referring to lost her own child and I have no doubt if they detected any amount of THC it would have at least been mentioned.
Personally I don't think its that bad of an idea depending on the situation. If someone drops 3 Valium and kills someone on the road shouldnt it be known?
Did not mention it, but took note of it.Noone mentioned the end. They are training the POLICE TO TAKE BLOOD RIGHT THERE JOHNNY ON THE SPOT!!!

You do make a point which should send a chill up the spine of any Texas members who are cavalier about smoking and driving. Meet the qualifications for automatic blood testing and then show intoxication levels of THC and you are double fucked. One because of the D.U.I. and two because the coppers now have probable cause to justify even more invasive searches.
