They need reasonable suspicion that you're on something to search you. Then they can arrest you for possession if you have anything on you.

They can't arrest you for the suspicion that you're high, at least not in most places. I seriously doubt that they could anywhere in the US.

In Washington it's not even the law that you have to identify yourself if a LEO requests it. IF they're charging you with a crime they are still (obviously) allowed to detain you and once you're brought before a judge you are required to identify yourself.

 

In most places, being high in public can get you a "public intoxication" charge. I don't see why Washington would be any different.

 

sorry cobra that's bullshit. being high is not illegal anywhere in the US that i know of. being high while driving or loitering, or committing some other crime will get you an additional charge but if i walk into a coffee shop high out of my mind and sit next to a table of cops they cannot and will not do sh*t. very different from public intoxication

 

Apparently, you've never been out West. Here, a cop will stop you for "interfering with a police officer" just for glaring at him.

 

lived 10 years in AZ and never had an issue with cops and weed in public but we're very far off topic now haha

 

Public Intoxication is generally not a charge in most places, it's a Drunk and Disorderly or a similar charge. It requires that you behave in a significantly disorderly manner.
