Modified Gas (Cannabis flos Cantourage): lineage from Compound Genetics and a single source

Where does Modified Gas come from and who cultivated it?

Modified Gas is a hybrid developed by Compound Genetics from the cross of First Class Funk and Grape Gasoline. The lineage comes from a description that has been confirmed directly at the source, rather than from a repeated mention. The genetics of both sources available for this entry refer to it as a hybrid, without assigning it to either indica or sativa strains.

The trail goes cold with the parents. Neither First Class Funk nor Grape Gasoline has an established origin with us, so the lineage of this strain ends one generation back. This is not a gap to be filled with assumptions: breeders are not obliged to disclose lineage, and descriptions circulating on forums can contradict each other. Adding grandparents based on intuition would create false connections with strains that have nothing to do with this one.

It is necessary to separate lineage from the commercial name. In the same context stands another entry with the term "Gas" in the name, Farm Gas, which comes from a completely different pair of parents, namely Sour Diesel and GMO. The common word in the name does not indicate any kinship in either direction. Strain names are created in breeding marketing, not in the lineage registry, and are sometimes assigned purely for the sake of aromatic association.

Which manufacturers supply Modified Gas to Polish pharmacies?

One. In our list of pharmacy entries, Modified Gas appears exclusively under the Cantourage brand and only in one variant, so there is nothing to compare between manufacturers. The registered name is Cannabis flos Cantourage; we consciously omit the numerical part that usually appears in such a name.

The reason for omitting the number is quite simple. The value declared by the manufacturer has a deviation of about one-tenth of itself, and the study describing this product does not provide any ranges, only one result. If transcribed into the article, it would pretend to be a measurement taken from the package that the patient holds in their hand, but such a measurement has not been made. Therefore, the content of the active substance remains on the leaflet and in the series documentation, and here we describe what the number does not convey. The manufacturer will receive a separate description. along with the rest of their assortment.

The wholesaler's offer is not stagnant. The permit for the acceptance of raw material expires after five years and can be revoked earlier, deliveries come in batches, and the pharmacy orders what is currently available from the distributor. An entry that has one manufacturer today may have two in six months or disappear from the list for several months. We maintain the current state in one place, in the list of strains available in Polish pharmacies, and it is there that changes are recorded, not in this description.

What does Modified Gas smell and taste like?

Descriptions of the aroma of this entry revolve around a sweet-fruity note with a distinct spicy and peppery background. There is also earthiness and a lavender accent, which is usually associated with the presence of linalool. All these descriptions come from one source and are sensory descriptions, not results from laboratory measurements.

The names of the terpenes explain part of these sensations, though not all. Peppery sharpness usually goes hand in hand with caryophyllene, floral softness with linalool, and citrus freshness with limonene, which this study places first in this profile. Myrcene is sometimes described as an earthy note. Farnesene, the fifth compound mentioned, has no established scent description at all, as the literature on it pertains to insects, not human olfaction.

One thing in this description draws attention due to its absence. Despite the name suggesting a fuel-like sharpness, the list of aromas for this entry does not mention either gasoline or diesel. The terms come from a closed industry taxonomy, in which such an entry was simply not anticipated, so its absence does not prove that no one perceives that note.

However, the aroma is not a promise of effect. The same terpene name appears in descriptions of strains perceived quite differently, and the intensity of the aroma depends more on harvesting and drying than on genetics. Dried flower kept in heat and light loses volatile compounds the fastest, so two packages from the same batch may smell different after a few weeks of sitting in a drawer.

How long does it take for Modified Gas to take effect and how long does the effect last?

For Modified Gas itself, there is no answer from measurement. No one has published a study on the duration of effect for this cultivar, so the ranges that can be honestly provided describe the method of administration, not this specific strain. The following numbers pertain to dried flower taken by inhalation or orally.

The route of administration determines the course more than the variety itself. After vaporization, the substance passes from the lungs to the blood almost immediately, so the first sensations appear after a few minutes, the intensity increases for another ten to thirty minutes, and the whole effect lasts for two to four hours. After ingestion, the raw material first passes through the intestine and liver, so the first sensations are awaited from half an hour to two hours, and the episode can last six, sometimes eight hours. Hence the most common mistake with oral administration: anyone who thinks nothing is happening after thirty minutes and takes another dose will receive both doses at once. The above ranges describe the route of administration, not this variety; pharmacokinetic studies for a single cultivar have not been published.

In the studies describing this strain, there is not a single sentence about the duration of action; they discuss composition and genetics, but pharmacokinetics are not addressed at all. Ultimately, it is not the name on the package that determines efficacy, but the method of administration established by the attending physician, as the range between inhalation and oral routes is greater than any difference between individual strains of dried flower.

What is known about the effects of Modified Gas, and what remains unverified?

Nothing is known about the effects of Modified Gas from clinical studies, as none have been conducted for it. What can be described pertains to individual terpenes from its profile and comes from studies on rodents. The rest of the descriptions circulating online are sales material or user reports.

The profile composition is described by one source, one industry database, and lists farnezen, kariofilen, limonen, linalol, and mircen; limonen is considered the leading compound. We do not replicate the proportions of these compounds, as it is unclear what they are calculated for: five values given in the same set sum to one hundred eighteen, not one hundred. The number without a denominator appears to be a measurement, but it is not.

For limonene, the evidence base for this project has two studies, both on rodents. Limonene administered intraperitoneally to mice showed muscle relaxant effects (rota-rod test) starting from a dose of 50 mg/kg and prolonged sleep induced by pentobarbital at a dose of 200 mg/kg (about 2.6 times); in the elevated plus maze test, already at a dose of 5 mg/kg, it reduced the number of entries into the open arms, which the authors described as an anxiogenic effect, not anxiolytic. This was described by Vale et al. in Phytomedicine (2002, PMID:12587690). The second study concerns inflammation and pain: Limonene reduced paw swelling induced by carrageenan in rats and pain responses in the formalin test in mice; the effect was associated with the l-arginine/nitric oxide/cGMP/KATP channel pathway and the involvement of opioid and benzodiazepine receptors. Fakhri et al., Behavioural Pharmacology (2025, PMID:40622197).

The boundary of this data must be stated clearly. No anxiolytic effects of limonen have been demonstrated in humans. It has also not been shown that isolated limonen has anxiolytic effects in animals; the only available data from the elevated plus-maze test showed an opposite effect in mice, reducing the number of entries into the open arms even at a low dose. Neither of the two studies examined dried flower or even a mixture of terpenes, only a single compound administered intraperitoneally, in doses not translatable to inhalation from a vaporizer.

What side effects have been reported after using Modified Gas?

None attributed to this name. The Polish reporting system links the description of an adverse effect to a specific medicinal product and batch number, not to the strain name, so there is no separate statistic for Modified Gas, and under the current reporting method, there cannot be. What remains is what has been documented for the entire group of raw material.

Reports of adverse effects are collected for medicinal products with a batch number, not for the strain name, so the following pertains to hemp dried flower as a group of raw materials. The most frequently reported symptoms are dry mouth, red eyes, and increased heart rate. Dizziness upon rapid standing, daytime drowsiness, and temporary worsening of short-term memory are less frequently described, as well as anxiety that increases with dosage. A separate issue is medications taken concurrently, especially sedatives and those affecting coagulation: their assessment requires knowledge of the entire list of preparations, not just the description of the plant. We do not provide the frequency of these symptoms numerically, as public compilations for hemp dried flower in Poland do not separate them by individual products.

For this strain, there is one more caveat. In our data, it has one pharmaceutical variant from one manufacturer, so the group of patients who could report anything is necessarily small. The silence surrounding the name does not therefore prove the mildness of the strain, but results from the small sample size and the way records are maintained.

What does the boiling temperature of terpenes say about the vaporization of this strain?

Less than the tables circulating on forums promise. The temperature set on the vaporizer is not the temperature of the dried flower, as the material cools the airflow upon inhalation, and the evaporation of the compound begins long before its boiling point. Therefore, aiming for a single number to extract a selected terpene is based on a misunderstanding.

The boiling points for this profile appear in the public database of chemical compounds as follows: mircen boils at about 167 degrees Celsius, limonen at about 178, linalol at about 195, and kariofilen only at about 257. For farnezen, the database does not provide a boiling point at all, so the fifth compound from this profile cannot be placed in the same series. This alone shows how valuable the tables comparing all terpenes side by side are. The above values were measured at a pressure close to atmospheric, and databases provide measurements for some compounds only under reduced pressure; placed in the same series alongside the previous ones, they are not approximations but distortions.

From the above, no recommended range can be derived, and we intentionally do not provide it. The method of administration, along with the temperature, is determined by the attending physician together with the patient, and the raw material seems to be dispensed according to the physician's prescription. We explain separately why ustawienie waporyzatora to it is not the temperature of the dried flower, and separately we gather knowledge about limonene itself.

Which strains from Polish pharmacies are related to Modified Gas?

Two: Gastro Pop and Pink Certz. Both have the same parent as Modified Gas, namely Grape Gasoline, and both come from the same breeding. The second parent is different in each of the three cases, so we are talking about half-siblings, not variants of a single line.

The differences begin precisely with this second parent. Gastro Pop was created from the crossing of Apples and Bananas with Grape Gasoline, and Pink Certz combines The Menthol with the same parent; they reach pharmacies under three different brands. The common ancestor does not translate into a common profile: the leading compound in the descriptions of these three products is considered to be myrcene, nerolidol, and limonene, respectively.

The list ends with two names, and this is a result, not a lack of data. We count siblings only where the common parent is an identified strain, not a broad family like Afghan or haze. Strains that only share such a category are not related in any useful sense, so we do not include them here. Also excluded from the list are strains that are not currently available in Polish pharmacies. The mere kinship does not suggest anything to the patient: it speaks of breeding work, not of how two related strains will act in the same person.

Frequently asked questions about Modified Gas

Is Modified Gas an indica or sativa strain?

The studies available for this strain refer to it as a hybrid and do not assign it to either of the two traditional groups. The division into indica and sativa strains today is based more on trade tradition than on researched origins, so it says little about what the patient can expect.

Who bred Modified Gas?

The strain was developed by Compound Genetics, and its parents are First Class Funk and Grape Gasoline. We do not have confirmed origins for the parents themselves, so the lineage of this strain ends at one generation back.

How many producers supply Modified Gas to Polish pharmacies?

In our data, one, Cantourage, and in one variant. However, the wholesale offer changes from month to month, so the number of producers listed in the strain description becomes outdated faster than the rest of this text.

Does limonene from this strain have anxiolytic effects?

This has not been demonstrated. Studies on rodents showed an effect contrary to expectations in the anxiety test, and a corresponding study on humans has not been conducted. Descriptions attributing calming effects to the strain come from sales materials or user reports.

Can Modified Gas be purchased without a prescription?

No. It is a pharmaceutical raw material in the Rpw category, dispensed only by a doctor's prescription. The strain description is not an indication for its use or an encouragement to reach for it.

Why don't you provide the active substance content for this strain?

Because the document describing this item provides a single number without a range, and the value declared by the producer has a deviation of about one-tenth of itself. A bare number would pretend to be a measurement made on a specific package, which no one has conducted.

The material is for informational purposes and does not replace medical advice. Dried flower is a pharmaceutical raw material dispensed by a doctor's prescription in the Rpw category and is not the same as dried flower available for retail sale. redakcja ubucha.pl.
