These are the consequences of cbd weed consumption in an unventilated place

If you have decided to open this article, you too, are part of that group of curious people who would like to know more about hotboxing (with CBD flowers too).

If it occurs unknowingly, you should know that this practice could be hazardous because it risks dulling the senses of those in the same room without having smoked.

Which would certainly be better.

In this article, we will discuss the phenomenon of hotboxing and its possible consequences for both smokers and non-smokers.

Do you already have the impression that this article is for you?

Let’s get started!

The origins of hotboxing with Herodotus

A long time ago, around 450 B.C., a Greek man known by the name of Herodotus, who is modernly referred to as the father of history. A historian and geographer, Herodotus wrote the ‘Histories’, a detailed account of the Greco-Persian wars that saw the Greeks and the mighty empire of Persia clash when Cyrus the Great conquered the region of Ionia.

Being a historian and a geographer, it is only natural that Herodotus travelled often.

He once travelled north to the region of Scythia in search of a mysterious plant called cannabis, and here he met a nomadic tribe of traders from the Altai Mountains in southern Siberia. Herodotus learned that in addition to using it to make carpets, clothes and ropes, the Scythians also used cannabis for burials.

The mourning ritual was intended to purify and cleanse the body and spirit: people would gather in a sealed tent, light a fire in the centre and burn hemp to mourn the loss of a member of their tribe until the smoke dissipated completely.

Yes, OK, but now you might be wondering what all this has to do with hotboxing.

Let’s find out in the next paragraph.

What is meant by hotboxing?

When you inhale the weed, you take in cannabinoids and terpenes that create the feeling that many people call a ‘high’.

The heat activates these elements and transforms them into smoke, eventually distributing them to the body.

But what about the rest of the smoke?

Theoretically, the smoke that is exhaled and the smoke that is naturally released from the end of a joint or blunt should also contain cannabinoids.

For this reason, some people would resort to hotboxing, with the aim of not wasting them. By inhaling smoke in a poorly ventilated room, one is believed to create an authentic ‘weed sauna’ and, as a result, get a more substantial ‘high’ feeling because cannabinoids would not be dispersed.

But is this the case?

Does hotboxing get you high? Here’s what research suggests

Maybe the Scythians didn’t precisely practice hotboxing under the guise of getting higher, but people in the 21st century certainly do.

But does it work?

About seven years ago, the John Hopkins School of Medicine researched the effects of room ventilation on non-smokers exposed to second-hand cannabis smoke.

The study consisted of putting six smokers and six non-smokers together for an hour inside a transparent thermoplastic and aluminium chamber to recreate the effect of hotboxing. Each smoking participant received ten joints containing one gram of cannabis with a THC content of 11.3% and was instructed to smoke deliberately.

All participants were subjected to two forms of exposure: ventilated and non-ventilated.

The research showed that exposure to second-hand smoke under non-ventilated conditions produced detectable levels of THC in the blood and urine of the non-smoking participants. In the words of the researcher, there were also:

  • slight increases in heart rate;
  • mild to moderate physiological and subjective effects;
  • mild impairment of a task requiring psychomotor skills and working memory.

On the other hand, exposure under ventilated conditions resulted in much lower blood cannabinoid levels, so we can conclude that passive cannabis smoking produced no sedative effects, no impairment of performance, and no positive urine test results.

So, hotboxing works in extreme, unventilated circumstances.

This means that one must be very careful. If one decides to purchase CBD weed, one must be aware of the possible effects on non-smokers in a closed room with poor ventilation.

In this article, we have discussed hotboxing, a phenomenon whereby inhaling second-hand hashish smoke in a stagnant place can produce much more potent effects.

In any case, we reiterate the importance of using hashish with awareness and buying it only from authorised and certified dealers. One of them is Justbob, the Italian portal that offers the best quality and legally compliant CBD buds.
