Cannabis sativa is a species of the Cannabis genus. It is an herbaceous annual plant native to tropical and subtropical regions of the world. Cannabis sativa is known for its tall, thin, and fibrous stem, used to make various products, including rope, paper, and textiles.


Cannabis sativa is also the source of marijuana, which is a psychoactive drug that is used for recreational and medicinal purposes. The plant contains high levels of the psychoactive compound THC (tetrahydrocannabinol), which is responsible for its psychoactive effects. Cannabis sativa is often used to produce a stimulating and energizing effect, and it is usually consumed by people who want to be more productive or creative.

When consumed, marijuana can produce a variety of effects on the body and mind, including:

  • Euphoria: Many people who use marijuana report feeling a sense of euphoria or happiness.
  • Relaxation: Cannabis sativa can produce a sense of relaxation in some users.
  • Increased appetite: Some people who use marijuana report an increase in appetite, commonly referred to as “the munchies.”
  • Altered senses: Marijuana can alter the way users perceive sights, sounds, and other stimuli.
  • Altered memory and concentration: Cannabis sativa can impair memory and concentration in some users.
  • Anxiety: In some people, marijuana may cause anxiety or paranoia.

It’s important to note that the effects of marijuana can vary widely from person to person, and they can depend on a variety of factors, including the strain of marijuana, the method of consumption, and the individual’s age, gender, and overall health. In addition, the use of marijuana can have adverse effects, including impairing judgment and coordination, and it can be addictive for some people.

There are several subspecies of Cannabis sativa, including Cannabis sativa L., the most commonly cultivated subspecies. Other subspecies include Cannabis sativa ssp. spontanea and Cannabis sativa ssp. afghanica.


It’s important to note that the possession, use, and sale of marijuana are illegal in many countries and states, and strict laws and regulations control it. In some places, the use of medical marijuana is allowed for specific medical conditions, but this is typically only with a doctor’s prescription and following local laws and regulations.
