A jury convicted Ira Jean Tensley of conspiracy to distribute cocaine and possession with intent to distribute cocaine, in violation of 21 U.S.C. §§ 841 and 846, and 18 U.S.C. § 2. The district court sentenced Tensley to concurrent terms of 240 months’ imprisonment and 235 months’ imprisonment respectively. On appeal, Tens-ley challenges the sufficiency of the evidence used to convict her on both counts. We affirm.

Facts

Seven witnesses provided the bulk of the evidence against Tensley. These seven witnesses — Harold Bateman, Edwin Slaughter, John McDuffy, Sr., John McDuffy Jr., Grady Hickman, Lorenzo Nunn, and Aly-cia White — related similar accounts of Tensley’s drug sales conducted from her residence in Davenport, Iowa. The sales occurred between January 1997 and March 24, 2001, and concluded with Tensley’s arrest. All seven witnesses testified that Tensley bought or sold cocaine or heroin to them at various times and in various amounts over the four years of Tensley’s operation. Some testified about Tensley’s drug transactions with other witnesses and about sales to additional unknown customers. Several witnesses observed Tensley mixing cocaine and heroin at her house, weighing the drugs on a small scale in her kitchen, and bagging the drugs in plastic bags for sale. They also saw Tensley use cocaine and heroin regularly at her residence.

In addition to these regular drug transactions, Tensley made special trips to procure drugs. Hickman testified that in June 1997, he made two trips to Chicago with Tensley to buy cocaine and heroin. On the first trip, Hickman, Michael Nunn, and Tensley drove to Chicago to pick up the drugs. According to Hickman, Tens-ley obtained a package that Tensley later told him contained heroin — but she was unable to complete the cocaine transaction. Hickman, based on his experience, estimated that the package contained approximately ten grams of heroin, an amount Hickman believed to be consistent with purchase amounts for heroin sales.

Hickman further testified that a couple of months later he, Nunn, Tensley, and a friend of Tensley’s again drove to Chicago to buy drugs. Hickman testified that they went to the same location, and Nunn arranged for the purchase of one-half of a kilogram of cocaine — financed in part by $3,000 contributed by Hickman towards the purchase of the drugs. Hickman testified that Tensley transported the drugs back to Davenport in exchange for the cocaine.

McDuffy, Sr. also testified about one of Tensley’s trips to Chicago. He observed Tensley transport two one-half kilogram packages of cocaine to Davenport. He believed this trip occurred in August 1998, and McDuffy, Sr. received one-half an ounce of the cocaine from Tensley after this trip.

Scott County Deputy Michael Hill testified about interviewing Tensley on October 20, 1999. During the interview, Tensley admitted that she had, over several occasions, purchased one-fourth of a pound of cocaine from McDuffy, Sr., one-sixteenth of an ounce at a time. Tensley also admitted that she bought heroin from McDuffy, Sr., and that she mixed heroin and cocaine into “speedballs.” Tensley further described that one to two years earlier, she and four others traveled to Chicago together to purchase powder cocaine. Tens-ley stated that they did not obtain any cocaine during the first trip. On a second trip, however, they drove to the same location in Chicago and Michael Nunn arranged for the purchase of a kilogram of cocaine for $12,000. According to Deputy Hill, Tensley also told him that Michael Nunn gave this cocaine to Tensley and Jones, which they transported back to Davenport. Once they successfully delivered the cocaine to Davenport, Tensley claimed she received $300 and Jones received some cocaine. Tensley admitted to Deputy Hill that she purchased one-quarter of an ounce of cocaine from Michael Nunn on three occasions.

Rock Island County Deputy Tom Shoemaker testified that he and other members of the task force discovered evidence of drug activity after the team conducted “trash pulls” from outside of Tensley’s residence. On January 14, 2001, members of the Davenport Police Department executed a search warrant at Tensley’s residence. Officers seized possible drug paraphernalia, and small amounts of substances that later tested positive for cocaine and heroin. Officer Gil Proehl testified that some seized items were consistent with the type of packaging used for illegal narcotics sales.

In her own defense, Tensley testified that she was addicted to cocaine and heroin. She admitted that she purchased drugs from Bateman and McDuffy, Sr. for personal use, but she disputed testimony that she resold those drugs. Tensley stated that she could only use up to fourteen grams of cocaine in one month. Tensley claimed that she purchased one-sixteenth of an ounce of cocaine seven or eight times from Bateman, but she denied buying three ounces per month because she could not personally use that much cocaine. She also denied buying two ounces of heroin a month and claimed that was much more than she could use. Tensley asserted that she bought one-eighth of an ounce of cocaine three times from Slaughter, but she denied that she bought two-and-a-half ounces a month as Slaughter stated. Tensley admitted that she bought amounts of one-sixteenth and one-eighth of an ounce of cocaine for personal use from McDuffy, Sr. and White, but denied ever buying any drugs from McDuffy, Jr. or Lorenzo Nunn. Tensley denied having any agreement with Michael Nunn or the government witnesses to distribute drugs. Tensley denied making the admissions described by Deputy Hill.

Standard of Review

In determining the sufficiency of evidence to support a conviction, “the relevant question is whether, after viewing the evidence in the light most favorable to the prosecution, any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.” Miller v. Lock, 108 F.3d 868, 870 (8th Cir.1997) (emphasis in original). We resolve eviden-tiary conflicts in favor of the government and accept all reasonable inferences drawn from the evidence that support the jury’s verdict. United States v. Ryan, 227 F.3d 1058, 1063 (8th Cir.2000). “A conviction may be based on circumstantial as well as direct evidence. The evidence need not exclude every reasonable hypothesis except guilt.” Id. “If the evidence rationally supports two conflicting hypotheses, the reviewing court will not disturb the conviction.” United States v. Gillings, 156 F.3d 857, 860 (8th Cir.1998). “The standard to be applied to determine the sufficiency of the evidence is a strict one, and the finding of guilt should not be overturned lightly.” Ryan, 227 F.3d at 1063.

A.

Conspiracy to Distribute Cocaine

Tensley first argues that the government’s evidence was insufficient to prove that she conspired to distribute cocaine. She contends that, at most, the evidence showed that she had a prolonged drug addietion-an addiction that impelled her to buy drugs from various people. Tensley argues the evidence failed to establish a conspiracy because it lacked proof of any agreement between her and others to sell drugs. The government responds that it based its case on strong circumstantial evidence from credible witnesses. The jury, exercising its prerogative, chose to believe those witnesses as well the other evidence gained from the “trash pulls” and the search of Tensley’s residence. This evidence, according to the government, amply supports a conspiracy conviction.

To support a conspiracy conviction, the government must show that: (1) a conspiracy existed for an illegal purpose; (2) the defendant knew of the conspiracy; (3) the defendant knowingly joined in it. United States v. Oleson, 310 F.3d 1085, 1089 (8th Cir.2002). The government can make its conspiracy case with either direct or circumstantial evidence. United States v. Jiminez-Perez, 238 F.3d 970, 973 (8th Cir.2001). Often, evidence in a conspiracy case will be circumstantial due to an illegal conspiracy’s “necessary aspect of secrecy.” United States v. Robinson, 217 F.3d 560, 564 (8th Cir.2000). A defendant’s mere presence and knowledge that someone else who was present intended to sell drugs are insufficient to establish membership in a conspiracy. United States v. Hernandez, 299 F.3d 984, 988 (8th Cir.2002). However, once a conspiracy’s existence has been established, slight evidence connecting a defendant to it may be sufficient to prove the defendant’s involvement. Id.

Seven different witnesses testified that Tensley agreed or acted with them to either purchase drugs, sell drugs to them, or sell drugs to others. In particular, testimony regarding the Chicago trips alone supports the jury’s finding that Tensley conspired with various people to buy cocaine and heroin for personal use as well as resale. The jury weighed the testimony of these witnesses in conjunction with Tensley’s statements to Deputy Hill and the evidence gleaned from the “trash pulls” and the search of Tensley’s residence. It chose to believe the witnesses and, to Tensley’s detriment, found she engaged in a conspiracy. Based upon our review, such a finding was a reasonable inference drawn from the evidence. Tens-ley’s sole defense is that these witnesses were lying; however, the jury determined otherwise, and credibility assessments are the province of the fact-finder. Hernandez, 299 F.3d at 989; United States v. Davis, 103 F.3d 660, 674 (8th. Cir.1996). As such, based on the testimony alone, the jury’s determination of Tensley’s guilt is supported by the record.

B.

Possession with Intent to Distribute Cocaine

Tensley next argues that the evidence did not support her conviction for possession with intent to distribute. She states three bases for her argument. First, Tensley challenges the credibility of the government’s witnesses based upon their plea agreements. Second, she contends the police seized no cocaine from her person or her home. And, finally, she argues that the items seized during the search were as consistent with drug use as they were with drug sales. As such, the evidence did not establish Tensley’s guilt beyond a reasonable doubt.

To convict for possession with intent to distribute, the government need only show that the defendant possessed the drugs with the intent to distribute them. United States v. Johnson, 18 F.3d 641, 647 (8th Cir.1994). Some factors that may lead to a conclusion that the drugs were intended for distribution include the quantity of drugs, packaging material, paraphernalia, and the presence of guns. United States v. Lopez, 42 F.3d 463, 467 (8th Cir.1994).

We hold the evidence supports the conviction. The fact that her co-conspirators made plea agreements with the government does not in and of itself prevent their testimony from being credited by the jury. See United States v. Cabrera, 116 F.3d 1243 (8th Cir.1997) (existence of plea agreements or offer of leniency in exchange for testimony is relevant for assessing credibility of witnesses, but it is within the province of the jury to make that assessment and resolve conflicting testimony). Deputy Hill testified that Tensley admitted that she used approximately fourteen grams of cocaine a month and that two ounces of heroin was more than she could use each month. However, the amount of drugs credited to Tensley far exceeded her admitted usage. As to the seized items, the jury resolved the conflicting hypotheses in favor of drug distribution rather than mere personal use, and we will not disturb their finding. Gillings, 156 F.3d at 860. Finally, based upon the volume of drugs Tensley bought each month from government witnesses, the jury could reasonably conclude that she possessed the excess drugs to sell to others.

For the reasons we have stated, we affirm.
