Formula química THC - Marihuana.png

What we commonly call marijuana is a plant called Cannabis , its psychoactive effects are due to one of its active principles, tetrahydrocannabinol (THC) . It is a plant with whose resin, leaves and flowers hashish and marijuana are made. The concentration of THC, in addition to other components, determines the potency of the derivatives.

Different substances can be obtained from Cannabis Sativa. Depending on which part of the plant is extracted, we find three different modalities:

What types of marijuana are there ?

Cannabis comes from a plant (Cannabis sativa), of which several subspecies are distinguished:




From which fibers and oil are mainly obtained




Poor in active principles. This type of Marijuana plants are native to America, Asia and Africa, where the climates are warm and the summers long.

More stimulating effect, predominantly euphoric. (Green House, J. 2014)




It contains a higher concentration of cannabinoids and from which more than 70 different compounds have been isolated, which differ depending on the variety, origin or climate.

Originally from Pakistan and India mainly, although they can be found from many other places. They have originally evolved in cold climates, where summers are short. Predominantly relaxing effect. (Green House, J. 2014)




All types of marijuana obtained by crossing indica strains with sativa strains. Hybrids can have the qualities of any of their parents, and can have more indica or sativa tendencies in any of their virtues, flavor, effect, production, morphology. (Green House, J. 2014)

Depending on its growth, flowering and sex it can also be classified into



Regular varieties are those that have been obtained naturally, by crossing a male marijuana plant with a female marijuana plant. The result offers us seeds that, when flowering, can be male or female and this result cannot be predicted. (Green House, J. 2014)



Feminized varieties are those that have been obtained by crossing a reverted female plant with a female plant, so that all the seeds obtained are female. They are the most demanded since they guarantee that the plants will be female, which are the ones that are smoked. (Green House, J. 2014)

What happens if I regularly use marijuana?

Continued consumption favors the appearance of the so-called amotivational syndrome, which is characterized by poor psychosocial behavior, apathy, low concentration capacity and memory deficits. (Rojas, J. Irala, J. Martìnez, M. 2006)

This syndrome is defined as a state of passivity and indifference, characterized by generalized dysfunction of cognitive, interpersonal and social capacities due to the use of cannabis for years. In the DSM (Manual for the diagnosis of mental illnesses) it is recognized that a dysthymic syndrome (depressive) may appear that would lead to lethargy (drowsiness), anhedonia (inability to feel pleasure), and mood disorders such as irritability.

The person becomes listless, lacking energy, without interest, often gaining weight, and appears extremely lazy. You are reluctant to do any prolonged activity that requires attention or tenacity. As a result, most of them have poor school and work performance, since they tend to present difficulties for study and learning.


Is it possible to develop addiction to marijuana ?

According to Kemp, Molly, Clark and Dobbs (2016) there is evidence of the appearance of tolerance, withdrawal and dependence both in experimental studies in animals and in studies with human consumers. This tolerance disappears if consumption is eliminated. Although some authors dispute the existence of the withdrawal syndrome, it has been tested in significant and long-term users. In habitual marijuana users for approximately 5 years, the suppression of THC consumption was accompanied by a set of characteristic symptoms, including anxiety, tension, insomnia, anorexia, fatigue, difficulty concentrating, irritability, dysphoria and aggressiveness, as well as symptoms and signs physical such as sweating, trembling, myalgia, nausea and diarrhea. This withdrawal syndrome has an average duration of 8 days.

It is possible that the difficulty in recognizing the withdrawal syndrome is due to the fact that marijuana, being a fat-soluble molecule, has a half-life in the body of approximately 7 days, which prevents a sharp drop in concentrations in the blood so the withdrawal pattern is not very specific and does not occur abruptly, it can take a couple of months for the body to be totally free of THC. In addition to this, the withdrawal syndrome has a clinical similarity with anxious or depressive pictures, which makes it easier to go unnoticed.

In addition, there is evidence that the withdrawal syndrome can vary depending on the route of administration of the substance and it is identified that one of the causes for continuing to use cannabis is to avoid the appearance of withdrawal syndrome. On the other hand, the pleasure associated with consumption can become an important psychological reinforcement.
