If his only option was to take you in for a blood test that means you couldn't get convicted or even charged, correct?
Well, his first option is always the field impairment test, it's difficult for a sober person to pass so if you are affected by drugs in any way you will probably fail it. This is in the UK btw, I believe blood tests are more common in the US.
A pupil dilation test. Designed to test for presence of drugs.
Counting out 30 seconds. Drug users either under-read or over-read time.
Walking in a straight line nine paces forward and then back. This classic test checks co-ordination and balance.
Raising a foot in the air six to eight inches off the ground. Designed to test balance.
Touching finger to nose with eyes closed. This tests co-ordination.
If you fail the field impairment test they call a doctor and he will assess you. They may or may not bother with a blood test.
