Okla. Stat. tit. 63, § 63-2-410

expungement - Persons not covered by section.

A. Whenever any person who has not previously been convicted of

any offense under this act or under any statute of the United States

or of any state relating to narcotic drugs, marijuana, or stimulant,

depressant, or hallucinogenic drugs, pleads guilty or nolo

contendere to or is found guilty of a violation of the Uniform

Controlled Dangerous Substances Act, the court may, unless otherwise

prohibited by law, without entering a judgment of guilt and with the

consent of such person, defer further proceedings and place the

person on probation upon such reasonable terms and conditions as it

may require including the requirement that such person cooperate in

a treatment and rehabilitation program of a state-supported or

state-approved facility, if available. Upon violation of a term or

condition, the court may enter an adjudication of guilt and proceed

as otherwise provided. Upon fulfillment of the terms and

Oklahoma Statutes - Title 63. Public Health and Safety Page 997

conditions, the court shall discharge such person and dismiss the

proceedings against the person. Discharge and dismissal under this

section shall be without court adjudication of guilt and shall not

be deemed a conviction for purposes of this section or for purposes

of disqualifications or disabilities imposed by law upon conviction

of a crime. Discharge and dismissal under this section may occur

only once with respect to any person.

B. Any expunged arrest or conviction shall not thereafter be

regarded as an arrest or conviction for purposes of employment,

civil rights, or any statute, regulation, license, questionnaire or

any other public or private purpose; provided, that, any plea of

guilty or nolo contendere or finding of guilt to a violation of the

Uniform Controlled Dangerous Substances Act shall constitute a

conviction of the offense for the purpose of the Uniform Controlled

Dangerous Substances Act or any other criminal statute under which

the existence of a prior conviction is relevant for a period of ten

(10) years following the completion of any court imposed

probationary term; provided, the person has not, in the meantime,

been convicted of a misdemeanor involving moral turpitude or a

felony. Records expunged pursuant to this section shall be sealed

to the public but not to law enforcement agencies for law

enforcement purposes. Records expunged pursuant to this section

shall be admissible in any subsequent criminal prosecution to prove

the existence of a prior conviction or prior deferred judgment

without the necessity of a court order requesting the unsealing of

such records.

C. The provisions of this section shall not apply to any person

who pleads guilty or nolo contendere to or is found guilty of a

violation of the Trafficking in Illegal Drugs Act or the Drug Money

Laundering and Wire Transmitter Act.
