Xanax is the brand name for a prescription benzodiazepine known as alprazolam. It is used to treat anxiety and panic disorders.[1] Xanax lessens anxiety by affecting gamma-aminobutyric acid (GABA) in the brain.

While Xanax is effective in treating anxiety, it is only intended for short-term or occasional use. Using it frequently can lead to dependence and addiction. If you take larger doses of Xanax than you are prescribed, you could experience a mind-altering high that is incredibly habit-forming.

Many people who abuse alprazolam look for Xanax bars, as they are the highest dose. Xanax bars contain 2mg of alprazolam. Unfortunately, many drug dealers press fake Xanax bars that could contain adulterants like fentanyl.

Because it is dangerous to abuse fake Xanax bars, you should be aware of what the real ones look like. There are green, white, yellow, and blue Xanax bars. While it is possible to identify them, some people press realistic-looking bars, making it vital that you avoid purchasing them on the street.

In this article, you will learn:

  • What is alprazolam?
  • What are the different types of Xanax bars?
  • How can you spot fake Xanax?

What is Xanax (Alprazolam)?

Xanax is a prescription benzodiazepine that is also referred to as alprazolam. Medical professionals use it to treat anxiety conditions like panic disorder. It can relieve panic attacks by enhancing the activity of a calming neurotransmitter called gamma-aminobutyric acid (GABA).

The side effects of Xanax may include:[1]

  • Dizziness and drowsiness
  • Light-headedness
  • Headaches
  • Fatigue and tiredness
  • Irritability
  • Chattiness
  • Difficulty concentrating
  • Increased salivation or dry mouth
  • Changes in sex drive or ability
  • Nausea and vomiting
  • Constipation
  • Changes in appetite and weight
  • Trouble urinating
  • Joint pain

If you use more Xanax than you are prescribed, you might experience a high characterized by euphoria, calmness, a sedative effect, and memory loss. Some people engage in strange behaviors while under the influence of Xanax, such as compulsive stealing. You might wake up after abusing Xanax without any memory of what you did.

Because Xanax can get you high, it is considered a Schedule IV controlled substance. You should not take the medication without medical supervision. Long-term Xanax abuse can lead to addiction, increased mental health issues, and a risk of life-threatening overdoses.

What are the Different Colors of Xanax Bars?

If you abuse Xanax, it’s important to know what the medication looks like. Without knowing how the pills are supposed to look, you are more likely to abuse fake versions of the drug. Unfortunately, fake Xanax could contain dangerous additives like fentanyl.

Most people who abuse Xanax look for “bars.” Xanax bars are shaped like bars with four indentations. They contain 2mg of alprazolam.

The different types of Xanax bars include:

Green

There are several different shapes of green Xanax. Some are oval-shaped, while others are triangular or round. There is also a green Xanax bar.

The shapes of green Xanax pills vary based on their dosage. For example, the oval green Xanax pills are 1 mg of alprazolam, while the bars are 2 mg.

People might call green Xanax bars “Hulks” or “green monsters.” Depending on what company manufactured the Xanax, there will be specific words or numbers imprinted on one side.

White

White Xanax pills range from 0.25 mg to 2 mg. They come in circular, oval, and rectangular or bar shapes. The white Xanax bars contain 2 mg of alprazolam.

White Xanax bars are known as “sticks” on the street. They have different words or numbers imprinted on them based on their manufacturer. They could have “Y21” or “XANAX” printed on one side.

Like all Xanax bars, the white ones have 4 imprints on them that make it easy to break them into smaller doses.

Yellow

Yellow Xanax pills are usually the generic version. They come as a circle, an oval, or a bar. Yellow Xanax bars are 2 mg and usually have an “R 0 3 9” printed on one side.

On the street, people call yellow bars “school buses.” Because of how popular they are, there are a lot of fake yellow Xanax bars.

Blue

Blue Xanax pills come in 1 to 2 mg. The circular and oval-shaped blue Xanax pills tend to be 1 mg, while blue Xanax bars are 2 mg. It is common for the blue bars to have “B 7 0 7” printed on one side.

Blue Xanax bars do not have popular street names, however, the 1 mg pills are often called “blue footballs” because many of them are shaped similarly to a football.

How to Spot Fake Xanax Pills

If you are prescribed Xanax, never take more than you are supposed to. If you run out, you might be tempted to buy some off of the street. Buying Xanax on the street is risky because there are so many fakes out there.

The only way to be certain that your Xanax is real is to obtain it from a pharmacy with a doctor’s prescription. That said, some signs indicate whether Xanax bought on the street is a pressed pill, including:

  • No markings on the pill
  • Uneven indentations
  • Xanax indentation being misspelled or unevenly spaced
  • Flat indentation of the word “XANAX” rather than it being three-dimensional
  • The color is extremely vibrant or off from the pictures on the pill identifier websites
  • The pills do not dissolve in water
  • The pills do not weigh approximately 0.5 grams
  • The pills shatter into pieces when crushed instead of being easy to break
  • Noticing a chalky residue from the pill

If you come across fake Xanax pills, never consume them. They could contain high doses of adulterants like illegally manufactured fentanyl, which often leads to drug overdose deaths.
