test for it like DUI( alcohol).

I don't think it can really work that way. Because unless there are new tests out, the one currently can't tell if you are actually high at the moment. It can only tell if you have been high in the last 30 days.

These test really shouldn't be for the presence of a chemical in your body, but should be testing your response to the physical environment, like a field sobriety test.

If you fail, you fail, whether its because you're drunk, stoned, taken too many sleeping pills, have the flu, you're old and have dementia ...

Is the purpose to keep the roads safe?
