This delivery, I will socialize information on the general characteristics, pharmacokinetic action, pharmacological effects, psychoactive effects, consumption and legal aspects of one of the main psychoactive species, in this opportunity on Cannabis sativa.
Introduction
Psychoactive flora is a group of plant species that synthesize substances analogous to neurotransmitters from the biological point of view and whose biochemical effect activates the transfer of nervous impulses in humans, generating alterations in the perception of space and time.
In addition to alterations in the perception of space and time, psychoactive plant species also act by transforming the normal conscious state into prolonged periods of euphoria, paranoia, agitation, anxiety and sleep, essentially through their hallucinogenic and narcotic effects.
However, considering the generalized perception that exists on the consumption of psychoactive plant species, in addition to the scarce technical-didactic information on their physiological and toxicological properties, the objective of the present post is to socialize botanical aspects related to the pharmacokinetic action, pharmacological and psychoactive effects of the Cannabis sativa species.
General features
Taxonomy and distribution
Cannabis sativa, is a plant species of herbaceous biotype, artificially located in the Division: Magnoliophyta., Class: Magnoliopsida., Order: Urticals., Family: Cannabaceae., Genus: Cannabis and Species: sativa, of Asian origin and extensive range in both temperate, tropical and subtropical eco-regions.
Common names
According to [1], Cannabis sativa is invariably identified as Marijuana, however, it is also often referred to as Hemp, Kalamu, Herb, or Bangue from India.
Vegetative and reproductive morphology
The specimens of Cannabis sativa, present herbaceous and erect stem, composed and palm-like foliar laminae (leaflets in variable number at the end of the rachis), lanceolate and accumulated aspect, with glandular trichomes in the segment of the beam and stipules in the zone of insertion of the petiole, serrated margin, alternate phyllotaxy, monochlamydial or appetal flowers (without petals), cimosa inflorescences and fruits type aquarius of ovoid morphology [2] .

Edaphoclimatology of Marijuana
Marijuana as a crop, physiologically expresses its maximum vegetative and reproductive potential in subtropical conditions, which present light intensity between 400 - 700 nm, average rainfall of 1,800 millimeters per year, temperatures between 20 and 25 ° C, humidity of 60 to 70%, exhibiting soil fertility high in calcium, potassium and humic substances, and slightly acidic pH 5.5 and 6.5.

Pharmacokinetic action
Conceptualization
Pharmacokinetics is the area of pharmacology that relates the biological movements of natural substances, or drugs in the human body, in the search for knowledge of their bio-absorption, distribution, extraction, bio-transformation, receptors where they act, in addition to the physiological and toxicological effects before their excretion from the body [3].
Pharmacokinetics of cannabinoid substances
In relation to the pharmacokinetic action of cannabinoid substances, the main compounds synthesized biologically by the psychoactive species Cannabis sativa, authors such as [4], indicate that the numerous processes developed in the human body by these psychoactive substances of Marijuana are; uptake by specific receptor proteins such as CB1 (central nervous system) and CB2 (gastrointestinal tract, peripheral nervous system, spleen and immune system cells), which is why, physiologically, they act on neuro-immune and endocrine activity, mediating neuromodulatory, antipsychotic and antiepileptic responses, and then they are distributed and metabolized by the liver, released or expelled through feces and urine.

Pharmacological effects
Clinical Answers
According to numerous clinical trials in children, the main pharmacological effects of psychoactive substances present in the vegetative and reproductive structures of marijuana (Cannabis sativa) are as follows: anti-inflammatory, antiemetic, muscle relaxant and analgesic, hence its use is recommended in multiple medical treatments to counteract severe pain, nausea, vomiting, epilepsy, sclerosis [5] .
Addictive effects of Cannabis sativa
Reported Toxicological Disorders
Within the innumerable addictive responses, that exert the psychoactive substances cannabinoids, products of the effects of sedation, relaxation, sensation of euphoria, creativity, constant hallucination, overestimation of the time, increase of the appetite, positive answers in psychiatric syndromes, such as depression, disorders of the dream, and before the absence of medical dosage by legal reasons, the consumption of Cannabis sativa generates addictive effects that create multiple toxicological upheavals and consequences on the health, like for example; psychosis, schizophrenia, mental problems, respiratory and cardiovascular diseases, however, it is necessary to indicate that the anxiety generated by the consumption of C sativa, ends up altering the behavior of the people when becoming totally dependent on the Marijuana, aspects that cause adverse social effects, as much at familiar level as work.

Cannabis sativa consumption and legal aspects
Legal provisions
Even though, on a global scale, amended legal provisions of the Single Convention on Narcotic Drugs of 1961 have been imposed, prohibiting the consumption of substances derived from Cannabis sativa, due to its stimulant and hallucinogenic effects, which have positioned Marijuana as an illegal drug, there are few controls or audits implemented in most countries of the world, to stop the health and social problems it generates in people who consume psychoactive substances of Cannabis sativa [6].
Use of Cannabis sativa psychoactive substances
The harmful effects of marijuana have probably not been an issue of government interest at the international level, hence, it is consumed illegally and exaggerated by the following forms; inhalation either smoked or vaporized, orally by infusion or maceration with alcohol, and sublingually for rapid absorption.
SCIENTIFIC CONTRIBUTIONS OF THIS PUBLICATION
- In summary, the thematic content presented on; physiological and toxicological properties of Cannabis sativa, provides synthesized information related to the general characteristics, pharmacokinetic behavior, pharmacological and psychoactive effects presented by Marijuana, in addition to focusing on the widespread failure to comply with the 1961 Single Convention on Narcotic Drugs, which prohibits the use of substances derived from C. sativa.
