Does Ruderalis Have THC?


Yes, Ruderalis does contain THC, but typically at much lower levels (~ 3%) compared to other cannabis subspecies like Cannabis sativa and Cannabis indica (~15-30%). Cannabis ruderalis is known for its higher CBD content and its unique characteristic of autoflowering, which means it transitions from the vegetative stage to the flowering stage based on age rather than light cycle. 

While Ruderalis itself is not commonly used for its THC content, it is often crossbred with other cannabis varieties to produce hybrids that benefit from its auto-flowering trait while maintaining higher THC levels from the other parent strains.

Is Ruderalis Legal?

The legality of Cannabis ruderalis, like other cannabis subspecies, depends on the laws of the specific country or region. Here are some general points regarding its legality:

United States: The legality of Cannabis ruderalis varies by state. In some states, cannabis is fully legal for both medical and recreational use, while in others, it may be legal only for medical use or illegal altogether. Federal law still classifies all cannabis varieties as illegal, although enforcement varies.

Canada: Cannabis, including Cannabis ruderalis, is legal for both medical and recreational use across the country.

Europe: The legality of Cannabis ruderalis varies by country. Some countries have legalized it for medical use, while others have decriminalized its use or maintain strict prohibitions.

Other Countries: In many parts of the world, cannabis remains illegal. However, some countries have legalized or decriminalized it for medical or recreational use.

Because Cannabis ruderalis is not typically sought after for its THC content, it might not be as heavily regulated as other cannabis subspecies, but it still falls under the general cannabis laws of the region.

Cannabis Ruderalis Vs Sativa & Indica

Cannabis is generally classified into three main subspecies: Sativa, Indica, and Ruderalis. Each subspecies has distinct characteristics that differentiate them in terms of appearance, growth patterns, chemical composition, and effects. Here’s a comparison of Sativa and Indica versus Ruderalis:

Cannabis Sativa

  • Appearance: Sativa plants are typically tall and thin with narrow leaves. They can grow up to 20 feet in height.
  • Growth Patterns: Sativa plants have a longer flowering cycle and are usually grown outdoors. They thrive in warmer climates with longer growing seasons.
  • Chemical Composition: Sativa strains generally have higher THC levels and lower CBD levels.
  • Effects: Sativa is known for its uplifting and energizing effects, making it suitable for daytime use. It is often associated with increased creativity and social interaction.
  • Medical Uses: Sativa is often used to treat depression, anxiety, and chronic pain due to its stimulating effects.

Cannabis Indica

  • Appearance: Indica plants are shorter and bushier with broad leaves. They typically grow between 2 to 6 feet tall.
  • Growth Patterns: Indica plants have a shorter flowering cycle and are often grown indoors. They are well-suited to cooler climates with shorter growing seasons.
  • Chemical Composition: Indica strains usually have higher CBD levels and moderate THC levels.
  • Effects: Indica is known for its relaxing and sedative effects, making it suitable for nighttime use. It is often associated with body relaxation and sleepiness.
  • Medical Uses: Indica is commonly used to treat insomnia, muscle spasms, and chronic pain due to its calming effects.

Cannabis Ruderalis

  • Appearance: Ruderalis plants are the smallest of the three, typically growing between 1 to 3 feet tall. They have thick, sturdy stems and small, broad leaves.
  • Growth Patterns: Ruderalis is known for its autoflowering capability, meaning it transitions from the vegetative stage to the flowering stage based on age rather than light cycle. It has a very short flowering cycle.
  • Chemical Composition: Pure Ruderalis strains generally have low THC levels and higher CBD levels.
  • Effects: Due to its low THC content, Ruderalis does not produce strong psychoactive effects. It is more commonly used for its medicinal properties, particularly for its CBD content.
  • Medical Uses: Ruderalis is often used in the breeding of medicinal cannabis strains to create hybrids with high CBD content and the autoflowering trait. It can be used to treat conditions like epilepsy, anxiety, and chronic pain.


Cannabis ruderalis contains low THC levels (around 3%) but is valued for its higher CBD content and autoflowering trait. Its legality varies by region, with differing laws in the U.S., Canada, and Europe. Unlike Sativa and Indica, Ruderalis is smaller, autoflowers, and is used primarily for medicinal purposes and breeding hybrids.
