Panama red

Panama red is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Panama red rather than just read about it. In short: Panama red, known as Panamanian red, or P.R. is a pure cultivar of Cannabis sativa. Renowned for its potency, it was popular among cannabis users of the 1960s and '70s.

Key takeaways

Panama red belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Panama red to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Panama red from memory before moving on to harder problems.

Reference excerpt

Panama red, known as Panamanian red, or P.R. is a pure cultivar of Cannabis sativa. Renowned for its potency, it was popular among cannabis users of the 1960s and '70s. The typically high THC levels associated with the variety are thought to be dependent on the particular cultivar, rather than the Panamanian climate. It induces a mellow cerebral high, slight body relaxation, characterized by euphoria and increase in energy, boosts creativity. It can cause anxiety and paranoia in some users. In a limited test, an Auburn University researcher reported that "seed of a sample of Panama Red, grown in the very different climates of the Canal Zone, when later cultivated on the Auburn campus and in northern New Hampshire, yielded marijuana with similar THC content." Its name comes from its cultivation in the country of Panama, and its claylike red color. Production was common in Panama's sparsely populated Pearl Islands. Cannabis cultivation died off in Panama with the rise of cocaine trafficking. On May 22, 2020, the season 2 of the animated Netflix's series Trailer Park Boys: The Animated Series was released. In the 6th episode "The First Time We Smoked Weed" Panama Red is frequently mentioned. The cultivar is mentioned in the 1999 film Detroit Rock City and the 2000 film Meet the Parents. "Panama Red" is the name of a song from the album The Yellow Balloon released in 1967 by the sunshine pop band The Yellow Balloon. It is also referenced in the 1979 film Apocalypse Now. The strain is frequently mentioned in the popular 1970s stoner comic The Fabulous Furry Freak Brothers. Thomas Pynchon references Panama Red several times throughout his works. The song "Panama Red" by Peter Rowan, was partly inspired by the strain; and the song "Amsterdam" by Van Halen refers to picking up Panama Red as a subject of the song.

Worked examples

Example 1 — a first encounter with Panama red

Start with the simplest possible case. Write down what Panama red claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Panama red before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Panama red ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Panama red

In research: Panama red appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Panama red in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Panama red is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cannabis strains, so understanding it makes those chapters shorter.
In everyday life: Look for Panama red outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
