EDINBURG - The Hidalgo County District Attorney's Office is making changes after a new addition to the state's drug laws.

They say they will still prosecute marijuana violations.

It all started with the legalization of CBD products.

They can contain small amounts of the main substance in marijuana that gets you high.

So now there's a challenge, differentiating what's legal and what's not.

For the county's prosecutor, it's still important to uphold the law.

"It doesn't change how we're going to proceed in prosecuting these cases, or how law enforcement will make a determination."

Now a concentration of 0.3% is allowed.

But during a traffic stop an officer can still use other evidence to build a case.
