Veronica Brown was charged with possession of a controlled dangerous substance, to wit: phenmetrazine (also known as pre-ludin endurets), in violation of R.S. 40:968(C), and forgery of a medical prescription by issuance or transference of a forged writing — a medical prescription for phenmetrazine — purporting to have been written and signed by a licensed medical practitioner with intent to defraud and with knowledge that the prescription was forged, in violation of R.S. 14:72, paragraph 2.1
At a jury trial on October 7,1976 defendant was found guilty as charged on both counts. She was sentenced on the possession charge to two years at hard labor and on the forgery charge to five years at hard labor, the sentences to run consecutively.
On appeal defendant assigns thirty-two errors as a basis for reversal of the conviction.
The facts surrounding commission of the crime follow.
On January 15, 1976 defendant Brown entered Briley’s Pharmacy in Winnfield, Louisiana, accompanied by Frank Williams, Jr. Due to an ongoing investigation in forged prescriptions of controlled dangerous substances, undercover narcotics agent Danny Moreau was secreted behind the pharmacist’s counter. Apparently, suspected prescriptions had been left at the pharmacy the day before and had been brought to Officer Moreau’s attention. In addition, Trooper Robert Rigby was stationed at the courthouse across the street while two other officers patrolled the area. The four officers were in contact with one another by walkie-talkie.
Defendant Brown requested a prescription in the name of Pinkie Jones, and Williams requested a prescription in the name of A. D. Ruth. Mr. Briley, the pharmacist, filled both prescriptions and handed them to Brown and Williams while alerting Mor-eau by hand signal that these were the questioned prescriptions. Ms. Brown stated *693that Williams would pay for the prescriptions, which he did.
Having observed the foregoing transaction, Moreau radioed Trooper Rigby that the suspects had just left the pharmacy. Rigby watched their movement to their car and alerted the other officers who stopped the car and arrested Brown, Williams and Billy Crishon, who was the driver of the vehicle. Pink pills were readily observable scattered on the front seat and floor boards in the front and back of the car, and were seized.
We find it necessary to reverse defendant’s conviction based upon Assignment of Error No. 32.2 Defendant contends *694that the trial court erred in denying a motion for a new trial based, among other things, upon the allegation that there was no evidence of the offense charged. We find that the record is devoid of proof of certain essential elements of the crimes with which defendant was charged.
R.S. 14:72, paragraph 2, the forgery statute which defendant is alleged to have violated, provides:
“Issuing or transferring, with intent to defraud, a forged writing, known by the offender to be a forged writing, shall also constitute forgery.”
There was sufficient proof offered that the prescriptions were forged. Chief Raymond Fargo, from the Office of Narcotics and Drug Control of the State Division of Health, testified that the two names found on the prescriptions, L. L. Lurent and C. J. Balm, purporting to be signatures of a physician or dentist, did not appear on the official list of persons licensed to prescribe controlled dangerous substances. Nor were these names registered with the Louisiana Board of Medical Examiners to practice medicine. Two physicians, whose names were similar to those on the prescriptions, were called to testify; both Dr. C. C. Laurent, Jr. and Dr. G. C. Bahm, Jr. testified that the signatures were not their own, and that they had not written prescriptions for the patients named.
There is lacking, however, proof of an essential element of the offense of forgery — knowledge that the writings were forged. The only evidence offered in this regard was proof that the prescriptions were forged, that Ms. Brown, along with Frank Williams, Jr., appeared at the store to pick them up, and that upon Ms. Brown’s arrest the pills were found scattered throughout the car. As a matter of law, this evidence was insufficient to prove the “scienter” element of the crime of forgery. There is no evidence that defendant knew the prescriptions were forged.
The same result follows in regard to the possession offense. R.S. 40:968(C) provides:
“It is unlawful for any person knowingly or intentionally to possess a controlled dangerous substance classified in Schedule III unless such substance was obtained directly or pursuant to a valid prescription or order from a practitioner, or as provided in R.S. 40:978, while acting in the course of his professional practice or *695except as otherwise authorized by this part. . . . ”
(Phenmetrazine is listed in Schedule III, R.S. 40:964(A)(1) and, therefore, is a controlled dangerous substance). It is necessary for the alleged offender to have knowledge that the prescription is not valid in order to violate the statute.
Thus, we hold that proof of an essential element of both offenses was lacking— knowledge that the prescription was forged (on the forgery charge) and knowledge that the prescription was invalid (on the possession charge). Therefore, the motion for a new trial should have been granted.
For the reasons assigned, the convictions are reversed, the sentences set aside, and the case is remanded for a new trial.
