It comes from a plant called Cannabis sativa L, which is grown in temperate and tropical areas whose main mind-altering psychoactive chemical is delta-9-tetrahydrocannabinol (THC). This substance is found in a resin that is prepared from the stems and leaves of the female cannabis plant. In addition to THC, it contains more than 100 related compounds called cannabinoids. It is THC that is responsible for cannabis being a highly addictive drug.


It is usually consumed by inhalation, but also in infusions and even with food. One way or another, faster in the first, the THC passes into the bloodstream and from there to the brain. When consumption is weekly or daily, it can be considered an addiction.

Marijuana can help fight the coronavirus, but don’t get too excited

Hemp (Cannabis sativa), from which marijuana is extracted, could join the arsenal of weapons against COVID-19 that we are gradually making available. At least, that’s the conclusion of a study recently published in the Journal of Natural Products. However, if you are thinking of smoking some joints to keep the coronavirus away, we are sorry to tell you that it will not do any good. The theme does not work like that.

What the study authors, from Oregon State University, have seen is that, in vitro (under laboratory conditions), it can affect the ability of the virus to infect our cells.

It is important to emphasize that it has only been seen in the laboratory, because a handful of cells grown in a Petri dish (those round plates used in laboratories) is not the same as those same cells forming part of a living organism full. What works one way may not work another. However, the results have been so promising that these researchers believe they could be on the right track for the future development of an antiviral based on two ingredients derived from hemp, from which marijuana is extracted.
