John Joseph Manning (“defendant”) appeals from judgment entered after a jury found him to be guilty of trafficking in marijuana pursuant to N.C. Gen. Stat. § 90-95(H)(l), possession with intent to sell or distribute marijuana pursuant to N.C. Gen. Stat. § 90-95(A), maintaining a dwelling for the purpose of keeping controlled substances pursuant to N.C. Gen. Stat. § 90-108(A)(7), and two counts of possession of drug paraphernalia pursuant to N.C. Gen. Stat. § 90-113.22. We find no error.
*132 I. Background
Around April 2001, Brian Gonzales (“Gonzales”) approached defendant and offered to pay him $1,000.00 per month to use defendant’s property to grow marijuana. Defendant agreed. Gonzales acquired two metal shipping containers and placed them on defendant’s property. One of the metal shipping containers measured approximately forty feet long, and the other was approximately twenty feet long. Both containers extended eight feet high.
Over a period of time covering three to five months, Gonzales, with defendant’s assistance, constructed marijuana growing facilities inside the containers. Gonzales testified defendant assisted in the construction and operation of the growing facilities inside the containers by: (1) installing the electrical lines for lighting; (2) installing water pumps; (3) diverting water from a well on defendant’s property to water the marijuana plants; (4) planting seeds; (5) picking out strains of marijuana that were sufficient for the operation; (6) growing seeds; and (7) harvesting the plants to sell.
On 3 April 2002, officers with the New Hanover County Sheriff’s Office obtained a search warrant and searched defendant’s residence and shipping containers. The officers cut locks off the container doors to gain access. Inside the containers, the officers discovered 731 marijuana plants in various stages of growth, lights, a sprinkler system, fertilizer, soil, and growth charts for the marijuana.
The officers called narcotics officers to the scene to collect and preserve the evidence found inside the containers. The narcotics officers collected the plants by cutting each plant above the root ball and placing them inside two thirty-gallon black plastic bags. The officers took the bags to the vice and narcotics office where they transferred the plants into more breathable brown paper bags.
On the following morning, 4 April 2002, Lieutenant Barney Lacock (“Lieutenant Lacock”) transported the brown paper bags containing the marijuana to Toledo Scales to determine the marijuana’s green weight — the plant material’s weight at the time it is harvested. James Martin (“Martin”), service manager at Toledo Scales, weighed the bags. The total green weight of the bags and their contents was 25.5 pounds.
During cross-examination Martin testified: (1) he did not possess personal knowledge about whether the scales were properly assembled; (2) the scale used to weigh the marijuana was newly assembled; *133 (3) if the scale was not properly assembled, it would not balance at zero; (4) if the scale balances at zero, it is correctly calibrated; (5) when he weighed the marijuana, the scales balanced at zero; (6) he had checked approximately 100 scales, and of those scales, only one was incorrectly calibrated, and it was manufactured by a different company than the scale in question; (7) the particular scale in question was sold sometime after the day it was used to weigh the marijuana; and (8) since that date, he had not received any service calls on that particular scale. Lieutenant Lacock testified that he observed Martin zero the scale.
After being weighed, the bags containing marijuana were transferred into three boxes and stored inside a drug vault at the New Hanover County Sheriffs Office. Some of the plant material decomposed while being stored. On 19 April 2002, the evidence was sent to the SBI laboratory, where it was analyzed and weighed again. On 7 May 2002, an SBI chemist recorded the marijuana’s dry weight to be 6.9 pounds.
On 25 August 2005, the marijuana was examined by Charles Williams (“Williams”), an expert for the defense in the fields of agronomy and horticulture. Williams agreed with the State that the only way to determine the true weight of the plant material, including stalks, roots, leaves, and flowers was to determine its green weight. Williams testified: (1) the plant material was significantly decomposed at the time he examined it; (2) approximately thirty to forty percent of the plant material was mature stalks; (3) approximately ten percent of the plant material had reached sufficient maturity to produce a flower or bud at the time law enforcement officers harvested the plants; (4) the stalks of a plant can be considered mature even if a plant is not ready to be harvested; (5) it did not appear that the mature stalks were separated from any of the other parts of the plants; and (6) the green weight of the marijuana plants, excluding the mature stalks, at the time of the seizure was 5.1 to 10.2 pounds. Defendant did not testify.
Defendant was tried before a jury on 27 February 2006. At the close of the State’s evidence, the trial court granted defendant’s motion to dismiss the charges of trafficking and conspiracy to traffic more than ten pounds by manufacturing.
The jury found the defendant to be guilty of: (1) trafficking in marijuana pursuant to N.C. Gen. Stat. § 90-95(H)(l); (2) possession with intent to sell and distribute marijuana pursuant to N.C. Gen. *134 Stat. § 90-95(A); (3) two counts of possession of drug paraphernalia pursuant to N.C. Gen. Stat. § 90-113.22; and (4) maintaining a dwelling for the purpose of keeping a controlled substance pursuant to N.C. Gen. Stat. § 90-108(A)(7). Defendant was sentenced to a minimum of twenty-five and a maximum of thirty months imprisonment. Defendant appeals.
II. Issues
Defendant argues the trial court erred in: (1) admitting evidence of the weight of the marijuana without adequate foundation that the instrument used to weigh the marijuana was properly assembled, calibrated, and tested and (2) failing to dismiss the charge of trafficking in marijuana because the State tendered insufficient evidence of the weight of the marijuana.
ITT. Weight of the Marijuana
A. Standard of Review
“The standard of review for this Court assessing evidentiary rulings is abuse of discretion. State v. Boston,165 N.C. App. 214 , 218,598 S.E.2d 163 , 166 (2004). A trial court may be reversed for an abuse of discretion only upon a showing that its ruling was so arbitrary that it could not have been the result of a reasoned decision. State v. Hayes,314 N.C. 460 , 471,334 S.E.2d 741 , 747 (1985) (citing State v. Wilson,313 N.C. 516 , 538,330 S.E.2d 450 , 465 (1985)).”
State v. Hagans,
B. Analysis
Defendant argues that the trial court erred in admitting evidence of the weight of the marijuana without an adequate foundation that the scale used to weigh the marijuana was properly functioning, maintained, and calibrated. We disagree.
Defendant contends the testimony showed: (1) the scales used to weigh the marijuana were assembled recently; (2) the person who weighed the plants had no knowledge of whether the scales were assembled or calibrated properly; and (3) no tests were performed on the scale to determine whether it was accurate.
In
State v. Diaz,
this Court considered a proper foundation for evidence of weight of marijuana.
In
Diaz,
Agent McLeod, the law enforcement agent present when the marijuana was weighed, described the procedure by which the weight was taken.
Here, the State’s evidence tended to show that “ordinary scales, common procedures, and reasonable steps to ensure accuracy” were utilized when the marijuana was weighed. Id. Martin and Lieutenant Lacock’s testimony established an adequate foundation that the scale used to weigh the marijuana was properly functioning. Martin testified: (1) if the scale was not properly assembled, it would not balance at zero; (2) if the scale balances at zero, it is correctly balanced; (3) the scale balanced at zero on the day he weighed the marijuana; (4) he had seen 100 or more of the particular scale model in question; (5) he assembled approximately twenty-five scales of the same model; (6) once the scale is assembled, it was normal procedure to put weight on the scale to check calibration; (7) over a period of twenty years he had checked approximately 100 scales, and of those scales, only one was incorrectly calibrated, and it was manufactured by a different company than the scale in question; (8) the particular scale in question was sold sometime after the day it was used to weigh the marijuana; and (9) he had not received any services calls on that particular scale. Lieutenant Lacock testified that he took the marijuana to Toledo Scales to be weighed and observed Martin zero the scale.
*136
Moreover, this Court noted in
Diaz
that “ ‘the weight element upon a charge of trafficking in marijuana becomes more critical if the State’s evidence of the weight approaches the minimum weight charged.’ ”
Id.
(quoting
State v. Anderson,
In support of his contentions, defendant cites
State v. Mason,
Both
Mason
and
Sibley
involve authentication of videotape recordings, which have specific requirements in laying a proper foundation for their admission.
Mason
sets out four elements needed to lay a proper foundation before a videotape can be admitted.
Diaz
only requires that the State present evidence of “ordinary scales, common procedures, and reasonable steps to ensure accuracy.”
IV. Motion to Dismiss
A. Standard of Review
The standard for ruling on a motion to dismiss is whether there is substantial evidence (1) of each essential element of the offense charged and (2) that defendant is the perpetrator of the offense. Substantial evidence is relevant evidence which a reasonable mind might accept as adequate to support a conclusion. In ruling on a motion to dismiss, the trial court must consider all of the evi *137 dence in the light most favorable to the State, and the State is entitled to all reasonable inferences which may be drawn from the evidence. Any contradictions or discrepancies arising from the evidence are properly left for the jury to resolve and do not warrant dismissal.
State v. Wood,
B. Analysis
Defendant argues the State presented insufficient evidence of the marijuana’s weight and that the trial court erred in denying his motion to dismiss the trafficking charge. We disagree.
Defendant claims the State included mature stalks in the weight of the marijuana, which are excluded from the statutory definition of marijuana. N.C. Gen. Stat. § 90-87(16) (2005). Defendant was indicted under N.C. Gen. Stat. § 90-95(h)(l), which provides:
Any person who sells, manufactures, delivers, transports, or possesses in excess of 10 pounds (avoirdupois) of marijuana shall be guilty of a felony which felony shall be known as “trafficking in marijuana” and if the quantity of such substance involved is in excess of 10 pounds, but less than 50 pounds, such person shall be punished as a Class H felon and shall be sentenced to a minimum term of 25 months and a maximum term of thirty months in the State’s prison and shall be fined not less than five thousand dollars ($5,000).
N.C. Gen. Stat. § 90-95(h)(l) (2005).
“Proving the weight of the marijuana is an essential element of the trafficking offense.”
State v. Gonzales,
“Marijuana” ... shall not include the mature stalks of such plant, fiber produced from such stalks, oil, or cake made from the seeds of such plant, any other compound, manufacture, salt, derivative, mixture, or preparation of such mature stalks, . . . fiber, oil, or cake, or the sterilized seed of such plant which is incapable of germination.
N.C. Gen. Stat. § 90-87(16) (2005) (emphasis supplied).
In
State v. Gonzales,
this Court held, “[t]hose parts of the plant not included in the statutory definition of marijuana,
such as the mature stalks
and sterilized seeds, are necessarily not to be included in the weight of the marijuana when determining a trafficking charge.”
Defendant must make an affirmative showing that the weight of the marijuana improperly included materials excluded from the definition of marijuana.
Id.
In
Gonzales,
this Court concluded “it is the defendant’s burden to show that any part of the seized matter is not ‘marijuana’ as defined.”
Once defendant offers evidence tending to show the total weight may have included mature stalks, the burden does not shift to the State for further evidence, as defendant contends. The issue of the “weight” of the marijuana becomes one for the jury. We held in
Gonzales,
“where the defendant does come forth with evidence that the State’s offered weight of the marijuana includes substances not within the definition (e.g., mature stems or sterile seeds), it then becomes the jury’s duty to accurately ‘weigh’ the evidence.”
The State met its burden on the issue of weight by presenting the testimony of Martin and Lieutenant Lacock that the marijuana’s green *139 weight was 25.5 pounds. Martin testified that he calibrated the scale, weighed the marijuana, and recorded its weight at 25.5 pounds. Lieutenant Lacock testified that he observed Martin zero the scale and weigh the marijuana. The State also offered evidence that the 25.5 pounds was the marijuana’s green weight. The marijuana was taken by Lieutenant Lacock and weighed the morning after it had been harvested. Defendant’s own expert agreed that the only way to determine the true weight of marijuana was to determine its weight at the time it was harvested. The SBI Laboratory determined the marijuana’s weight to be 6.9 pounds. This weight was taken a month after the marijuana had been harvested and only represented the marijuana’s dry weight.
Defendant’s expert witness, Williams, estimated between thirty to forty percent of the plant material appeared to be mature stalks and twenty to forty percent, or 5.1 to 10.2 pounds, of the original green weight was leaves and flowers. Using defendant’s expert’s estimate that forty percent of the plant material was mature stalk, the total weight of the remaining marijuana would be 15.3 pounds, more than the ten pound minimum required by the statute. Under
Gonzales,
defendant was allowed to present this evidence to rebut the State’s evidence and this evidence only creates an issue of fact for the jury to determine the “weight.”
The State presented sufficient evidence tending to show the weight of the marijuana exceeded ten pounds to overcome defendant’s motion to dismiss the trafficking charge. This assignment of error is overruled.
V. Conclusion
The State established a proper foundation and presented sufficient evidence to introduce evidence that the weight of the marijuana seized from defendant exceeded the ten pound minimum as required by statute. Defendant received a fair trial, free from prejudicial errors he preserved, assigned and argued.
No Error.
