OPINION
delivered the unanimous opinion of the Court.
Aрpellant was convicted in a bench trial of possession of marihuana, a usable amount of less than two ounces. Punishment was assessed at twenty days’ confinement in the county jail. The Court of Appeals affirmed the trial court’s conviction. We granted review to decide whether the Court of Appeals erred when it held that the arresting officer’s identification of marihuana was admissible as a lay opinion under Texas Rule of Evidence 701. 1 We will affirm.
*534 Appellant was the passenger in a vehicle that was stopped by Officer Nicole Saval. During the traffic stop, Saval smelled alcohol and the odor of burning marihuana emanating from the vehicle and suspected that the driver of the vehicle was under the influence. While Saval questioned appellant, another officer performed a field sobriety test on the driver who was subsequently arrested. Saval asked appellant if she and the driver had been smoking marihuana. Appellant first denied that she had been smoking marihuana and claimed that the odor was cigarettes. After Saval explained to appellant that cigarette smoke does not smell like marihuana smoke, appellant admitted that she and the driver had been smoking marihuana. Appellant then told the officer that there was more marihuana in the vehicle, which Saval found in a clear plastic bag between the two front seats.
Saval documented her identification of the marihuana in the offense report that was given to appellant before trial. After receiving the offense rеport, appellant requested and the court ordered the State to provide notice of its intent to offer expert testimony pursuant to Article 39.14(b) of the Texas Code of Criminal Procedure. The State did not respond to the order.
At trial, Saval testified about her police academy training. She stated that the trainees were shown what different drugs looked like and were able to smell marihuana both before and after it was burned. She stated that although she was not a drug recognition expert and was not certified as one, based on her training at the academy and her experience on the police force, she was able to identify what marihuana looks and smells like.
During Saval’s testimony, appellant objected claiming that the State was attempting to qualify Saval as an expert without providing notice. The State responded that Saval was not being offered as an expert under Rule 702, rather as an individual who can identify what marihuana looks and smells like. The court withheld ruling on the admissibility and allowed the testimony to continue. At the end of the trial, the court concluded that the officer was testifying as an expert due to her specialized knowledge, however, the testimony was admissible because the offense report was adequate notice.
On appeal, appellant claimed that the testimony of the officer was improperly admitted due to the State’s failure to provide notice of intent to offer expert testimony. Appellant also claimed that without this testimony, the evidence was legally insufficient to support a conviction.
The Court of Appeals concluded that the testimony was admissible as lay opinion testimony under Rule of Evidence 701.
Osbourn v. State,
Appellant advances two grounds for review but in view of our disposition of the *535 case only ground two will require discussion. The issue raised by the determinative ground of error is whether the Court of Appeals erred when it held that a police officer’s identification of marihuana is admissible as a lay opinion under Texas Rule of Evidence 701. 2
Appellant argues that the Court of Appeals erred when it held that the officer’s testimony regarding the identifiсation of marihuana was admissible under Rule of Evidence 701. Because Saval’s opinion was based on the training she received at the police academy and the experience she gained during her three years as a police officer, appellant contends that she was an expert witness under Rule 702. Appellant claims that only a witness who testifies based on personal knowledge, rather than experience and training, can identify marihuana as a lay witness under Rule 701.
The State counters appellant’s assertion by claiming that expert testimony is not necessary to identify marihuana because appellant herself identified the substance as marihuana. Additionally, the fact that all police officers have training and experience does not necessarily make them expert witnesses. The State contends that since Saval personally observed the marihuana, she was not testifying as an expert.
Both lay and expert witnesses can offer opinion testimony. Rule 701 covers the more traditional witness^one who “witnessed” or participated in the events about which he or she is testifying — while Rule 702 allows fоr a witness who was brought in as an expert to testify. A witness can testify in the form of an opinion under Rule 701 if the opinions or inferences are (a) rationally based on his or her perceptions and (b) helpful to the clear understanding of the testimony or the determination of a fact in issue.
Fairow v. State,
When a witness who is capаble of being qualified as an expert testifies regarding events which he or she personally perceived, the evidence may be admissible as both Rule 701 opinion testimony and Rule 702 expert testimony. A person with specialized knowledge may testify about his or her own observations under Rule 701 and may also testify about the theories, facts and data used in his or her area of expertisе under Rule 702. Texas Rules of Evidence Manual art. VII-6-7 (6th ed .2002) states that: “A witness may qualify to give testimony both under Rule 702-because of his or her superior experiential capacity-and under Rule 701, if the witness’s testimony and opinion are based upon firsthand knowledge.” This court has never addressed the issue of whether someone with training and experience can testify as a lay witness but the Courts of Appeals have admitted such testimony as both lay and expert opinion.
See e.g., Harnett v. State,
The ninth circuit has addressed the issue of whether a police officer with experience and training can testify as a lay witness.

In
United States v. VonWillie,
A distinct line cannot be drawn between lay opinion and expert testimony because all perceptions are evaluated based on experienсes. However, as a general rule, observations which do not require significant expertise to interpret and which are not based on a scientific theory can be admitted as lay opinions if the requirements of Rule 701 are met. This is true even when the witness has experience or training. Additionally, even events not normally encountered by most people in everyday life do not necessarily require the testimony of an expert. The personal experience and knowledge of a lay witness may establish that he or she is capable, without qualification as an expert, of expressing an opinion on a subject outside the realm of common knowledge.
United States v. James Earl Paiva,
It does not take an expert to identify the smell of marihuana smoke. Testimony as to the identity of an odor is admissible in some instances even though the person testifying is not an expert.
Chess v. State,
The admissibility of evidence is within the discretion of the trial court and will not be reversed absent an abuse of discretion.
Powell v. State,
Using the standard set out above, Saval’s observation that the odor she smelled was marihuana did not require significant expertise to interpret. And, her observations were not interpreted based on a scientific theory. Thus, if her testimony meets the requirements of Rule 701, it is admissiblе as a lay opinion. Rule 701 allows a lay witness to give testimony in the form of opinions or inferences that are rationally based on the witness’ perception and helpful to a clear understanding of the witness’ testimony or the determination of a fact in issue. Thus, if the witness perceived events and formed an opinion that a reasonable person could draw from the facts, thеn the first part of the rule is met. If the opinion is also helpful for the trier of fact to understand the witness’s testimony or aids in the determination of a fact in issue, then the opinion is admissible under Rule 701: Here, Saval participated in the events about which she testified and her opinion was based on what she perceived at the scene of the traffic stop. That is, she smelled an odor that she recognized as marihuana smoke. And, the testimony was helpful to the determination of a fact in issue (ie., whether appellant was in possession of marihuana). Her belief or inference that the substance was marihuana was based on identifiable facts that were within her personal knowledge such as the green, leafy appearance and the distinct odor. Unlike othеr drugs that may require chemical analysis, marihuana has a distinct appearance and odor that are familiar and easily recognizable to anyone who has encountered it. So Saval’s opinion that appellant possessed marihuana, based on the odor she smelled and the green, leafy substance she saw, was one that a reasonable person сould draw from the circumstances. Her testimony regarding the identification of the marihuana was admissible as a lay opinion under Rule 701.
The record also indicates that appellant objected to Saval’s testimony on the basis that her opinion was based on her training and experience as a police officer, making her a Rule 702 expert witness. There are certain fields where a witness may qualify as an expert based upon experience and training, however, use of the terms “training” and “experience” do not automatically make someone an expert. All opinions are formed by evaluating facts based on life experiences including education, background, training, occupation, etc. While Saval may have had the рotential to be qualified as an expert because she possessed knowledge, skill, experience and education, she was not testifying as an expert when she identified the marihuana. Rather, she was testifying based on her firsthand sensory experiences. Saval herself *539 smelled the odor that she perceived to be burnt marihuana. The fact that she had smelled marihuana before in the course of her employment as a police officer does not necessarily make her an expert. And, again, even if she was an expert, that would not preclude her from offering a lay opinion about something she personally perceived.
Although the trial court admitted Saval’s testimony under a different theory, because evidence supports admissiоn of the testimony under Rule 701, the trial court did not abuse its discretion. Consequently, the Court of Appeals correctly upheld the trial court’s admission of the testimony. The judgment of the Court of Appeals is affirmed.
Notes
. Unless otherwise noted, all future references to Rules refer to Texas Rules of Evidence.
. Appellant also argues that because the State did not provide notice of intеnt to offer expert testimony, the Court of Appeals erred when it held that Article 39.14(b) of the Texas Code of Criminal Procedure did not require exclusion of the State's expert testimony. However, since we find the testimony admissible as a lay opinion under Rule 701 we will not discuss Appellant’s first ground.
. Rule 702 states that "If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education may testify thereto in the form of an opinion or otherwise.”
. Although we are not bound by federal court decisions, when the Texas Rule is similar to the Federal Rule, cases interpreting the Federal Rules of Evidence can be used for guidance.
