yes, even harris county its been an option for a while but many officers are just pigs and choose not to exercise this option cuz they get paid more and are off the violent streets more for proceedings

Marijuana punishment change? - 8/01/08 - Houston News - abc13.com

Since last year, Travis County has started writing pot citations and Colorado and Dallas County are about to begin. Harris County is not exercising the option. People caught with four ounces or less of marijuana are still taken to jail. In 2000, there were 6,737 arrests, last year there were 9,790.
Clarence Bradford who is the democratic candidate for Harris County District Attorney supports the citation policy.
Republican DA candidate Pat Lykos is open to the possibility.
Neither candidate for sheriff supports citations over arrest.

"You also have to look at it like this, you write them a citation, what are the chance they're not going to show up for court," asked Harris County Sheriff Tommy Thomas who is also the Republican candidate. "Then it goes to warrant. Then we have to go out and find them."

"For the message to be communicated that it's ok, it's just a ticket, then you're sending the wrong message," said Adrian Garcia who is the Democrat candidate for sheriff.

Regardless of whether a person is ticketed or arrested though, the penalty for possession of up to four ounces of marijuana remains the same, anywhere from six months to a year in jail plus a fine.
we need a union of smokers, cuz these police people have their money tightly watched and they got organizations to back them up!
