It is best for people looking for cheap cannabidiol (CBD) oil to consider the product’s price and the producer’s safety practices. One way of choosing a cheap CBD oil is to check the price per serving rather than the price per bottle.

The table below shows how the pricing differs between the CBD oils:

This article discusses how to shop for cheap CBD oil, whether cheap CBD oils are safe, and some of the best oils available online.

Is CBD legal?The 2018 Farm Bill removed hemp from the legal definition of marijuana in the Controlled Substances Act. This made some hemp-derived CBD products with less than 0.3% THC federally legal. However, CBD products containing more than 0.3% THC still fall under the legal definition of marijuana, making them federally illegal but legal under some state laws. Be sure to check state laws, especially when traveling. Also, keep in mind that the Food and Drug Administration (FDA) has not approved nonprescription CBD products, and some products may have inaccurate labels.

CBD is a compound in the Cannabis sativa (C. sativa) plant. This plant contains compounds called cannabinoids, including tetrahydrocannabinol (THC), which causes the “high” people associate with cannabis use.

CBD cannot legally contain more than 0.3% THC, so people are unlikely to experience euphoria while using CBD products.

The FDA has approved a prescription CBD drug to treat seizures that result from certain conditions. However, the FDA does not regulate or approve any other CBD products.

Animal and human trials suggest CBD may have significant pain-relieving, anti-inflammatory, and anxiety-relieving effects. However, more research is necessary to determine how CBD can help with different conditions.

Companies that sell CBD may use several terms. The following table defines the most common CBD terminology.

TermMeaning
CBDA compound within the C. sativa plant that does not create the high sensation individuals commonly associate with cannabis use.
THCA compound in the C. sativa plant. It is the psychoactive compound that creates the high sensation from cannabis use.
Full-spectrumA full-spectrum product will contain all of the natural compounds in the cannabis plant, including THC. However, THC levels must be no more than 0.3% to comply with Food and Drug Administration (FDA) regulation on full-spectrum CBD products.
Broad-spectrumBroad-spectrum products contain natural compounds of the cannabis plant. However, while manufacturers remove all or most of the THC in broad-spectrum CBD, it may still be present in trace amounts.
CBD isolateThis is the purest form of CBD and should contain 0% THC.
CannabinoidsThe compounds within the cannabis plant, of which there are over 120. CBD is the second richest compound in the plant after THC.
TerpenesAnother compound of the C. sativa plant, terpenes typically give plants their specific aromas. Some terpenes, such as limonene, may have specific health benefits.
Certificate of analysis (COA)Reputable manufacturers of CBD products should ensure a COA is available for inspection. A COA provides information on the third-party testing that independent labs conduct on a particular product. Sometimes, products have a scannable smartphone code directing people to the COA online.

Many companies sell CBD at a lower price. However, it is important to consider whether a company is reputable.

Companies that offer CBD at a higher price will usually provide a COA, which certifies that a laboratory, often owned by an independent third party, has tested the products to ensure they contain the ingredients the company claims it does on its website.

One way to determine whether CBD oil is cheap is to compare different products by cost per serving.

Products with a higher dose of CBD per milligram (mg) are more likely to be expensive. However, a person will likely need less of a high dose product to notice an effect.

People may wish to consider the following before making a purchase:

  • Price: Products are available for different budgets. The price can vary depending on the bottle size and CBD content. Some companies also offer subscriptions to help returning customers save money.
  • Third-party testing: Companies should provide a COA for each product to verify that the product is safe for use and contains the amount of CBD and THC the company claims it does.
  • Ingredients: Besides CBD, oils will contain a carrier oil and may contain essential oils or fragrances. It is important to check the ingredients list to ensure that a person is not allergic to them.
  • Type of CBD: CBD comes in three types: full-spectrum, broad-spectrum, and CBD isolate. Full-spectrum CBD contains up to 0.3% THC, whereas broad-spectrum and CBD isolate contain neither this compound nor trace amounts.

Here we answer some common questions about CBD oil.

Does CBD oil show in a drug test?

Legal CBD cannot contain more than 0.3% THC. While drug tests that screen for THC should not show a positive result if a person takes CBD, it is possible for a person who takes it to fail a drug test.

This may be due to improper labeling of products or contamination with excess THC. For example, a 2019 study found that 25% of the CBD-infused foods the researchers looked at contained intoxicating levels of THC.

What makes some CBD oils more expensive?

Companies are more likely to charge more for CBD oil if it contains more per container. Additional factors that affect the price include the size of the bottle and whether it has undergone third-party testing.

Does CBD oil have side effects?

CBD products’ most common side effects include drowsiness, sleepiness, diarrhea, decreased appetite, and irritability.

Is it legal to use CBD oil?

CBD from hemp is legal on a federal level.

However, some states have not legalized CBD products. It is important to check state laws to ensure it is legal to purchase and use CBD oils in the state a person resides in.

What is the cheapest way to take CBD oil?

People who do not wish to spend much on their CBD oil may look for a company offering subscriptions. This usually includes more than one CBD pack at a reduced price.

Why doesn’t Walmart sell CBD oil?

Walmart does not sell CBD oil, as the products have many regulations. CBD manufacturers list all the ingredients on their website and provide a lab result document, factors that consumers may consider.

What is the most economical form of CBD?

CBD tinctures seem affordable, as some cost less than $40.

There are several cheap CBD oils available to purchase online. People should always ensure they are purchasing from a company that displays an up-to-date COA.

CBD is not legal in all states. People should check their state laws before committing to a purchase.
