What Are THCa Pre-Rolls?

What Are THCa Pre-Rolls?

By Jill Raver

THCa Pre-Rolls are new to the Cannabis scene and gaining massive traction. Similar to joints or blunts, pre-rolls are smoked. However, because they are derived from Hemp and are made with THCa (which is not psychoactive until it is heated) THCa Pre-Rolls are federally legal in the United States. So, what are THCa Pre-Rolls?

Let’s start at the beginning:

What Is THCa?

THCa is the abbreviation for tetrahydrocannabinolic acid. THCa is the precursor to THC (tetrahydrocannabinol) which is the psychoactive compound found in Cannabis. When THCa is heated it converts into THC. Hemp-derived THCa products, like THCa Pre-Roll, are available for sale throughout the United States. 

Is THCa Legal?

Yes, Hemp-derived THCa is federally legal in the US. Hemp and THCa are not controlled substances. Following the passage of the 2018 Farm Bill, Hemp and Hemp-derived compounds that contain no more than 0.3% Delta 9 THC by dry weight became legal in the United States.

Is THCa Psychoactive?

Despite its close ties to THC, THCa is not a psychoactive compound. However, this compound turns into THC when it is heated and, therefore, becomes a psychoactive compound. So THCa won’t cause psychoactive effects, but when a product like THCa Pre-Rolls is smoked, the THCa becomes THC, so the product offers psychoactive effects.

What Is The Difference Between THC and THCa?

THC and THCa are both naturally occurring cannabinoids. The main differences are their molecular formula, chemical structures and psychoactive properties. 


Psychoactive: Yes

Molecular formula: C21H30O2

Chemical Structure: Central core is composed of three rings; two benzene rings fused to a cyclohexane ring; a side chain containing a pentyl group (5-carbon chain) with a hydroxyl group at the end is attached to the cyclohexane ring


Psychoactive: No

Molecular formula: C22H30O4

Structural Difference From THC: Additional carboxylic acid group attached to cyclohexene ring

What Are THCa Pre-Rolls?

THCa Pre-Rolls are Hemp products that contain raw Cannabis flower that has not been decarboxylated. When you smoke pre-rolls, the THCa flower becomes THC. The psychoactive effects occur quickly.

What Do THCa Pre-Rolls Do?

Pre-rolls are basically legal Hemp joints that are smoked just like a traditional Marijuana joint or blunt. When ignited, the THCa in the pre-roll breaks down into THC. The effects are very similar to smoking Marijuana. Depending on the strain the effects can vary.

What Are The Benefits of THCa Pre-Rolls?

THCa Pre-Rolls offer the same benefits as smoking Marijuana but in a legal form. So, the main benefits of this product are using it recreationally for its intoxicating effects and the ability to purchase it legally. 

Some potential therapeutic benefits of THCa joints are:

  • Relaxation
  • Improved sleep
  • Reduction in stress and anxiety
  • Improved comfort
  • Increased appetite 
  • Nausea reduction

Can THCa Pre-Rolls Get You High?

Yes, you are likely to enter an altered state when you smoke pre-rolls. This is because of the conversion to THC once the THCa is heated. The effects of THC are psychoactive, meaning that they will get you high. 

Does THCa Get You As High As Delta 9 THC?

THCa will not get you high at all on its own. However, when THCa is exposed to heat it converts to Delta 9 THC. So technically, no - THCa by itself won’t get you high, but once it converts to THC, the effects are the same as any other Delta 9 THC smokable product. 

Which Is Stronger: Delta 8 or THCa?

When THCa is converted by heat, it becomes Delta 9 THC. Delta 9 is a stronger THC than Delta 8 THC. When we look at comparable doses of Delta 8 and Delta 9, the effects tend to be more intense with Delta 9, and milligram to milligram Delta 9 is at least twice as potent as Delta 8 THC.  

Will THCa Pre-Rolls Make Me Fail A Drug Test?

When you smoke THCa Pre-Rolls, the THCa becomes THC. As far as how it shows up and stays in your system, using pre-rolls looks no different than smoking Marijuana or THC. Drug tests typically test for THC. So yes, it is likely you will fail a drug test after smoking THCa. 

How Long Does THCa Stay In Your System?

The length of time THC from THCa stays in your system is the same as when you consume traditional THC products or smoke Marijuana. THC can remain in your system (urine) anywhere from a few days to over a month. Many factors can affect how long THC remains in your body. Some of these factors include

  • Frequency of use
  • Metabolism
  • Body fat percentage
  • Dosage
  • Potency

THC may flush out of your system faster when you drink more water and increase exercise. For more information read our blog, How Long Does Delta 9 Stay In Your System.

Are THCa Pre-Rolls Good For Pain?

Many studies have shown that Marijuana and THC can reduce inflammation and help with a variety of pain. So, these THCa products that convert to THC when used offer the same potential benefits. 

Are THCa Joints Good For Sleep?

If Marijuana or THC helps you sleep better, then you are likely to encounter the same result with pre-rolls. Here is a useful study that discusses Cannabis use for insomnia and other sleep disorders. You may also like Delta 9 Gummies For Sleep and Delta 8 Sleep Gummies.

Are THCa Pre-Rolls Good For Anxiety?

Since these pre-rolls convert to THC, they may help reduce anxiety, especially at lower doses. Higher doses of THC can result in anxiety and paranoia. So, if you want to try pre-rolls for anxiety, start with a lower dose and gradually increase until you get to the therapeutic level that is right for you. Here is more information on Cannabis for anxiety
