OPINION OF THE COURT
Cоntrary to his plea, the appellant was found guilty of using cocaine, in violation of Article 112a, Uniform Code of Military Justice, 10 U.S.C. § 912a (1982 and Supp. V 1987). A military judge sitting as a special court-martial sentenced the appellant to a bad-conduct discharge. The convening authority approved the sentence.
The appellant assigns the following errors:
I.
THE MILITARY JUDGE ERRED BY FINDING APPELLANT GUILTY OF AN OFFENSE NOT CHARGED BY THE GOVERNMENT.
II.
APPELLANT’S CONVICTION CANNOT BE SUSTAINED BECAUSE THIS COURT CANNOT DETERMINE WHETHER THE ACT OCCURRED WITHIN THE PERIOD CHARGED BY THE GOVERNMENT.
We disagree with both contentions and affirm.
Both assertiоns of error are directly related to the date and location alleged in the specification and the dates and location found by the military judge by exceptions and substitutions. The appellant’s conviction of cocaine use was based on the results of a random urinalysis held at his unit at Fort Hood, Texas, on 12 July 1990. He was charged with wrongfully using cocaine “at or near Fort Hood, Texas, on or about 12 July 1990.” The military judge convicted the appellant of using cocaine “at some
I.
As part of its proof, the government presented the testimony of an expert witness from the drug-testing laboratory that processed the appellant’s urine sаmple. The expert explained the laboratory’s procedures, how the body produces benzoylecgonine (the metabolite used to indicate сocaine ingestion), and how benzoylecgonine is detected by scientific analysis of the urine.
II.
If scientific-test evidencе is used by the government to meet its burden of proof, the government must provide a rational basis for understanding this evidence. United States v. Hunt,
Only when time is the essence of the offense do allegations concerning the date become a matter of substance. United States v. Brown,
Because it is often impossible to prove the exact date and location of drug use, and because time and location are not the essence of the offense, there is some latitude permitted in pleading and proving offenses of this sort. In reviewing a urinalysis case involving “on or about” pleading, the Navy-Marine Court of Military Review observed:
[T]he Government merely рled the date the appellant was tested by urinalysis rather than the more flexible standard practice of pleading “during the period ... to ... ”, which is generally designated a date commencing sometime prior to the date the servicemember submitted a specimen for urinalysis testing to and including the date of testing. In short, the Govеrnment pled the date the offense was discovered rather than the date it was committed. That period of inclusive dates used is that which conforms to the scientifically found and accepted life of the metabolite that identifies the controlled substance in the human system.
Esslinger,
In entering his findings, the military judge in the instant case was utilizing this “morе flexible standard practice” described by the Navy-Marine court. Therefore, we can understand why the military judge excepted the date of 12 July and substituted a period of time ending with 12 July, and found that the use of cocaine occurred at an unknown location.
We hold that any minor variances causеd by pleading the date of the urinalysis or in the military judge’s findings by exceptions and substitutions do not constitute error. Even assuming, arguendo, that the military judge erred by changing the “on or about” date to a period of nine days, the error was not prejudicial to the appellant. By lengthening the period of time, the military judge, in effect, created a greater double-jeopardy protection for the appellant than existed with the “on or about” language. Lee,
We find that the evidence is legally and factuаlly sufficient to prove the appellant’s guilt beyond a reasonable doubt. Jackson v. Virginia,
III.
The appellant, pursuant to United States v. Grostefon,
The finding of guilty and the sentence are affirmed.
Notes
. The appellant’s defense was innocent ingestion. Both he and a nephew testified that the ingestion probably occurred at a party following a softball game at Fort Worth on 11 July, the night beforе the random urinalysis. The witnesses testified that the cocaine may have been in the punch served at the party because they saw cocaine being used a few feet from the punch bowl. When they noticed cocaine being used at the party, they immediately left the party at the appellant’s suggestion. By his findings, it is clear that the military judge rejected the defense theory.
. See United States v. Boulden,
. In this regard, the defense counsel’s strategy and the questions he asked the expert witness аre similar to those described in United States v. Sparks,
. This same study was one of two discussed in United States v. Sloan,
. While we understand the military judge’s reasoning in the present case, it was not necessary that he find by exceptions and substitutions since the “on or about” language of the specification was sufficiently precise without amendment. The military judge’s decision to find by exceptions and substitutions, while not required, was likewise not error.
