If high CBD marijuana doesn't get you high can you still be arrested for DUI ?

Police when they stop you . Might arrest you for many reasons.
There is law in regards to a measured number of something.

There is also a law that you are not capable of driving in a safe manner. Hint someone that is extremely tired, having some medical issue like a stroke, a blood sugar issue. Or just being a bad driver.

Will you be convicted or just released in a few hours depends on situation. There is not one answer for every smoker for every possible degree of medical issue.

DRE conducts a standardized, diagnostic 12 step examination of persons arrested or suspected of drug-impaired driving or similar offenses. Based on the results of the examination the DRE develops an expert opinion.
One of these steps is the NUMBER from the test.

RCW 46.61.5249
Negligent driving—First degree.
(1)(a) A person is guilty of negligent driving in the first degree if he or she operates a motor vehicle in a manner that is both negligent and endangers or is likely to endanger any person or property, and exhibits the effects of having consumed liquor or marijuana or any drug or exhibits the effects of having inhaled or ingested any chemical, whether or not a legal substance, for its intoxicating or hallucinatory effects.

b) "Exhibiting the effects of having consumed liquor, marijuana, or any drug" means that a person has the odor of liquor, marijuana, or any drug on his or her breath, or that by speech, manner, appearance, behavior, lack of coordination, or otherwise exhibits that he or she has consumed liquor, marijuana, or any drug, and either:
(i) Is in possession of or in close proximity to a container that has or recently had liquor, marijuana, or any drug in it; or
(ii) Is shown by other evidence to have recently consumed liquor, marijuana, or any drug.
(c) "Exhibiting the effects of having inhaled or ingested any chemical, whether or not a legal substance, for its intoxicating or hallucinatory effects" means that a person by speech, manner, appearance, behavior, or lack of coordination or otherwise exhibits that he or she has inhaled or ingested a chemical and either:
(i) Is in possession of the canister or container from which the chemical came; or
(ii) Is shown by other evidence to have recently inhaled or ingested a chemical for its intoxicating or hallucinatory effects.

These laws don't really make any sense. Most of them were made by intensely angry republicans who would do ANYTHING to control marijuana - nobody really knows why.

So don't look for any of the laws like this to make any sense. They're as senseless as the republicans who make them.

Feeling high is legally irrelevant. Impairment of your ability to drive is the legal issue. You CAN be convicted of DUI when under the influence of legitimately prescribed medications used as directed.
