Black Tuna (Cannabis flos S-LAB): who supplies it and what is not known about it

Where does Black Tuna come from and can its lineage be established?

It cannot. The lineage of Black Tuna has not been disclosed by the breeder, and the available descriptions do not consistently indicate any parental pair. In the database of this cluster, the strain is listed as unknown, and so it remains: entering parents by guesswork would create a false kinship with cultivars that share only part of the name.

The name suggests a lot but means nothing. In this collection, the common element may be a pure coincidence: cultivars bearing the same word may have separate or even unestablished origins, so relying on the name when reconstructing genealogy leads nowhere. Therefore, with this strain, you will not find a statement about the parents, even if it sounds credible.

The source describing Black Tuna classifies it as a hybrid with a sativa dominance, but this information also comes from a single source, not from two independent ones. The division into sativa and indica, moreover, says more about the plant's growth habit than about what the patient will experience after vaporization, and does not replace a description of the chemical composition.

The lack of lineage is not a gap in this text, but rather its result. Commercial breeders rarely publish complete crosses, and the registration documentation for pharmaceutical raw materials does not require indicating parents, because for the quality of the batch, consistency matters, not genetic history. A strain without disclosed origin enters the pharmacy under the same conditions as any other.

Who introduces Black Tuna to Polish pharmacies?

One entity. According to the collected data, the strain is introduced into the Polish market exclusively by S-LAB, so there is no choice between versions from different manufacturers or comparison of batches. The entire presence of Black Tuna in pharmacies depends on the commercial and logistical decisions of one company, not on parallel submissions from several suppliers.

We provide THC content as a range, not as a single number, and this results from the tolerance allowed for the raw material. The manufacturer's declaration allows for a deviation of around ten percent in either direction, so for this strain, it is reasonable to read the THC content as 16.2-19.8%. A batch at the upper limit of the range and a batch at the lower limit both comply with the same declaration.

A single supplier has one more consequence, less obvious than the lack of version choice. A production break, change of registration, or withdrawal of a batch means that the strain disappears from pharmacies entirely, without a substitute from another producer. The remaining products of this producer are described in a separate text about S-LAB, and the current state of availability is maintained a comparison of strains available in Polish pharmacies. Each of these items is issued by a doctor's prescription in category Rpw, while our store shelf with dried flower collects products made from industrial hemp, which this mode does not cover.

What does Black Tuna smell like and where does this scent come from?

Resinous and piney, as far as the chemical profile suggests anything here. The scent of the dried flower comes from volatile compounds, and in this strain, the composition indicates pinene as the leading position, which is a note associated with pine resin. However, sensory descriptions are not measured in a laboratory and remain a report, not a parameter of the batch.

The rest of the profile adds background. Caryophyllene brings a peppery tone, limonene a citrus note, linalool a floral scent, nerolidol a woody aroma, and ocimene a herbal-sweet fragrance. The proportions between them determine what is felt upon opening the package, but none of the available sources for this strain provide proportions in a way that allows for comparison.

The scent is not constant over time. Terpenes are volatile, so dried flower stored in warmth with air access loses the lightest fractions first, and these are responsible for the initial impression. The same strain from two batches or from two storage moments can smell noticeably different, and this does not indicate a mistake in dispensing.

Flavor in vaporization spreads together with aroma, as the temperature set on the device extracts compounds sequentially, not all at once. At lower settings, light resinous notes are primarily noticeable, while at higher settings, heavier, spicy undertones emerge. The order of evaporation is broken down in a separate text about the temperatures at which terpenes leave the dried flower.

How long does it take for Black Tuna to take effect and how long does it last?

It depends on the method of administration, not the strain name. Dried flower vaporized acts quickly and briefly, swallowed slowly and for a long time, and the difference between the two is measured in hours. There is no separate measurement for Black Tuna, so the ranges below describe the behavior of the substance in the body.

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.

The practical implication is this: the timing of taking the substance translates into the length of the episode, not just its intensity. The strain shapes the character of the effects, while the schedule is determined by the method of administration, which decides whether the evening dose will end before sleep or only in the morning.

What has been shown in studies on pinene, and what remains anecdotal?

Very little has been demonstrated, and exclusively outside of humans. Two studies on pinene, the leading component of this strain's profile, concern mice and cell cultures. Everything read in commercial descriptions about the effects of Black Tuna on well-being comes from user reports or manufacturer materials, not from clinical research.

Yang and colleagues (Molecular Pharmacology, 2016, PMID:27573669) administered (-)-alpha-pinene orally to mice and demonstrated an increase in NREM sleep with shortened sleep latency using EEG and EMG recordings. The mechanism turned out to be direct: the compound bound to the benzodiazepine site of the GABA-A receptor as a partial modulator. The intensity of NREM sleep and the duration of REM sleep did not change.

The second study (Kim and colleagues, The American Journal of Chinese Medicine, 2015, PMID:26119957) did not involve an animal but rather peritoneal macrophage cultures stimulated by LPS. In this study, alpha-pinene reduced the secretion of IL-6, TNF-alpha, and nitric oxide, as well as the expression of iNOS and COX-2, inhibiting the MAPK and NF-kB pathways. This is a result from a test tube and should be read as such.

No anxiolytic or analgesic effects of pinene have been demonstrated in humans; available data only concern its effects on sleep in mice after oral administration and its anti-inflammatory effects on mouse macrophages in culture.

The terpene profile of this strain is described by one source, a Polish pharmaceutical compilation, which lists caryophyllene, limonene, linalool, nerolidol, ocimene, and pinene. You will not find percentage shares here, and this is not an oversight: compilations provide values without a common denominator, and summed values can clearly be less than the total sample, so comparing them between strains would be blind counting.

What side effects have been reported for this strain?

None attributed to this strain. The reporting system in Poland links observations to a specific medicinal product and batch number, not to the cultivar name, so a separate compilation for Black Tuna simply does not exist. What can be described relates to the entire dried flower issued in pharmacies, not to this single item.

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.

It is worth distinguishing two things that are often mixed in strain descriptions. The THC content affects how easily one crosses the threshold at which anxiety or increased heart rate occurs; the range of 16.2-19.8% places this strain in the middle of the scale found in Polish pharmacies. The terpene composition, however, has no documented impact on the frequency of such symptoms in humans, although it is sometimes presented in commercial materials as if it did.

At what temperature does dried flower with pinene vaporize?

Lower than intuition suggests. Pinene is one of the lightest compounds in this profile and evaporates earlier than most others, so at high settings, it disappears with the first puffs. However, temperature tables from different sources provide different values for the same compound, so it is better to read them as a guideline rather than a setting.

The discrepancy between the tables has a prosaic cause. The boiling point measured for a pure compound under laboratory conditions is not the same as the temperature at which that same compound leaves the plant material in the device's chamber. Additionally, the number displayed on the vaporizer describes the heating element or chamber, not the dried flower inside it. This difference is elaborated in a separate text about ustawieniu waporyzatora wobec rzeczywistej temperatury suszu.

For the profile led by pinene, it follows that a session conducted from lower settings to higher allows for the lighter fractions to be perceived first, and only then the heavier background. None of these numbers indicate how much substance actually passes into the inhaled aerosol, as this is not measured under home conditions. Why the temperature comparisons can be incomparable is explained in a text about discrepancies between the tables.

Which strains from Polish pharmacies are related to it?

None that could be proven to be related. The pedigree graph in this cluster does not assign Black Tuna any parents or siblings, and with undisclosed origins, there is no basis for establishing a connection. An empty list is a result here, not a lack of data, and it will not be filled in by guesswork.

One can indicate a different kind of proximity, based on composition rather than genealogy. Strains in which pinene occupies a leading position are described in a common discussion of this compound, while the remaining positions in the profile have their separate texts: caryophyllene, limonene, linalool, nerolidol and ocymen.

Such proximity should not be read as lineage. Two strains with similar compositions may come from entirely separate breeding lines, and two sister strains can differ in profile, as the content of volatile compounds is also determined by the cultivation method and post-harvest processing. Therefore, kinship speaks to the history of the seeds, while composition reflects what is actually in the package, and these two orders cannot be directly compared without measuring a specific batch. a list of available strains, aktualizowana wraz ze zmianami asortymentu.

Frequently Asked Questions about the Black Tuna strain

Is the lineage of Black Tuna known?

No. The breeder has not disclosed the parental pair, and the available descriptions are inconsistent, so in this cluster, the strain has an undetermined origin. The shared name component with other cultivars does not prove anything here.

How many producers supply Black Tuna to Polish pharmacies?

One. According to the collected data, the strain is marketed exclusively by S-LAB, so there are no versions from competing producers that could be compared.

What THC content is reported for this strain?

Considering the allowable tolerance of the producer, the THC content ranges from 16.2% to 19.8%. A single number on the label describes the declaration, not the measurement result of a specific batch of dried flower.

Which terpene leads in the profile of Black Tuna?

Pinene, according to the only source describing the composition of this strain. Besides it, caryophyllene, limonene, linalool, nerolidol, and ocimene are mentioned, without specifying percentage shares.

Has sedative action of pinene been demonstrated in humans?

No. The effect on sleep was noted in mice after oral administration, and the second available study concerned the cultivation of mouse macrophages. Transferring these results to humans would be an overinterpretation.

Does Black Tuna have sister strains in Polish pharmacies?

No. Without an established lineage, it is impossible to indicate siblings, and the kinship graph in this cluster leaves an empty list for this strain.

In what mode is this strain dispensed?

Exclusively by prescription from a doctor, in the Rpw category. Dried flower remains a pharmaceutical raw material, and the decision on its use lies with the attending physician.
