Opinion

OPINION

GARDNER, Justice.

I. INTRODUCTION

A jury found Appellant Cortez Jackson guilty of intoxication manslaughter and assessed punishment at sixty years’ confinement. Appellant raises nine points on appeal.

In his first point, Appellant complains that the State’s expert testimony concerning the level of cocaine in his system was speculative and conjectural. Appellant contends in his second and eighth points that the trial court erred in refusing to grant a mistrial. He argues in his third point that the trial court erred in admitting a document over his objections. In his fourth point, Appellant alleges the trial court erred in allowing the State to impeach him with convictions that were more than ten years old. Appellant asserts in his fifth through seventh points that the trial court erred in failing to charge the jury on the law of necessity, duress, and negligent homicide. Finally, Appellant claims the trial court erred in denying his motion for a directed verdict. We affirm.

II. BACKGROUND

Thomas Shepard was driving around attending to errands in Grand Prairie when Appellant passed him driving a red Explorer at a high rate of speed, almost rear-ending another car and cutting in front of him. Shepard then witnessed Appellant run two red lights on either side of a nearby highway underpass, turn, and disappear. As Shepard pulled into a gas station, he saw the red Explorer again. While Appellant pumped his gas, Shepard observed him “dancing around” to loud music coming from his car. When Appellant was finished, he drove over the curb and down the grass embankment to the street. Shepard then left the gas station and encountered Appellant’s car sitting crossway in the middle of the street. As Shepard began to stop, Appellant drove off, once again driving over the curb. Shepard then called 911 to report Appellant’s erratic driving.

*586 Shepard followed Appellant while talking to the police department on his cell phone. Appellant proceeded to travel in excess of 100 miles per hour and passed a tractor-trailer by cutting into the oncoming lane of traffic, missing the front of the tractor-trailer by a foot and a half. Appellant ran another red light, struck James Woods’s car, and killed him.

Appellant was taken to the hospital, where a sample of his blood was drawn. Testing revealed that Appellant had cocaine in his system. Appellant testified that he had smoked crack cocaine at about 5:30 the morning of the accident, about five hours before the accident occurred. Chris Heartsill, the toxicologist who tested Appellant’s blood, testified that ingesting enough cocaine to result in a high blood concentration would have resulted in behavior consistent with Appellant’s purported behavior at the gas station and his erratic driving.

III. EXPERT TESTIMONY

In his first point, Appellant contends the testimony of the State’s expert concerning the level of cocaine in Appellant’s blood at the time of the accident was speculative and conjectural. Specifically, Appellant complains about the State asking Heartsill whether Appellant had a high, medium, or low level of cocaine in his blood at the time of the accident.

Texas Rule of Evidence 702 permits a witness who is “qualified as an expert by knowledge, skill, experience, training, or education” to testify “in the form of an opinion or otherwise” if “scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue.” Tex.R.Evid. 702. Such testimony must not be substantially outweighed by the danger of unfair prejudice, confusion of the issues, or other factors. Id. 403.

Any examination of the admissibility of expert testimony must begin with Kelly v. State, 824 S.W.2d 568 (Tex.Crim.App.1992). The test adopted in Kelly “applies to all scientific evidence offered under Rule 702.” Hartman v. State, 946 S.W.2d 60, 63 (Tex.Crim.App.1997). Accordingly, we will determine whether Appellant met his burden of establishing the scientific reliability of the testimony under the Kelly standard. Kelly, 824 S.W.2d at 573.

Once it is determined the proffered evidence is relevant, the proponent of scientific evidence has the burden of proving its scientific reliability by clear and convincing evidence. Id. To satisfy this burden, the proponent must make a technical showing, outside the presence of the jury, demonstrating: (1) a valid underlying scientific theory, (2) a valid technique applying the theory, and (3) that the technique was properly applied on the occasion in question. Id.; Jordan v. State, 928 S.W.2d 550, 555 (Tex.Crim.App.1996). Factors that may influence a trial court’s determination of reliability include: (a) the extent to which the underlying scientific theory and technique are accepted as valid by the relevant scientific community, if ascertainable; (b) the qualifications of the expert testifying; (c) the existence of literature supporting or rejecting the underlying theory and technique; (d) the potential rate of error of the technique; (e) the availability of other experts to test and evaluate the technique; (f) the clarity with which the underlying theory and technique can be explained to the court; and (g) the experience and skill of the person who applied the technique on the occasion in question. Kelly, 824 S.W.2d at 573.

We will not disturb the trial court’s decision to admit expert scientific testimony absent an abuse of discretion. Hinojosa v. State, 4 S.W.3d 240, 251 (Tex.Crim. *587 App.1999). That is, if the trial court’s decision to exclude the evidence falls within the “zone of reasonable disagreement,” we will not interfere. Montgomery v. State, 810 S.W.2d 372, 391 (Tex.Crim.App.1991) (op on reh’g).

Appellant states that opinions that are speculative or conjectural are not admissible even if the witness is an expert. See Naegeli Trans. v. Gulf Electroquip, Inc., 853 S.W.2d 737, 741 (Tex.App.—Houston [14th Dist.] 1993, writ denied). Appellant argues that the question of whether the level of cocaine in his system was high, medium, or low is not based on any theory generally accepted in the scientific community. He thus contends it is impossible to cross-examine the witness because high, medium, and low are not definite measurements.

During his testimony, Heartsill, a toxicology chemist, described the process he used to test for alcohol and drugs in a sample of blood. He explained that the machines used to test Appellant’s blood were working properly. Heartsill testified that at the time he tested Appellant’s blood, he identified the presence of 0.08 milligrams of lidocaine per liter and 0.10 milligrams of cocaine per liter. He explained that cocaine has a half-life of 0.7 to 1.5 hours, which can be used through extrapolation to determine the level of the drug in the blood at an earlier time. He testified that this process is generally accepted in the forensic community as being accurate and reliable. In Heartsill’s 'opinion Appellant had a high level of cocaine in his system at the time of the accident.
