Which of these terms is NOT a common slang for cannabis?
Grass
Pot
Ganja
Shroom
While grass, pot, and ganja are all widely recognized slang terms for cannabis, "shroom" refers specifically to psychedelic mushrooms, not cannabis. Mixing up slang can lead to some funny misunderstandings. Shroom is popular in the psychedelics community but totally unrelated to weed.
Which region is cannabis originally native to?
Africa
Central Asia
South America
Europe
Botanical and genetic research indicates that Cannabis sativa originated in Central Asia, particularly around modern-day Mongolia and southern Siberia. From there, it spread to various parts of the world through ancient trade routes. Its adaptability helped it become one of the most widely cultivated plants globally.
In which part of the cannabis plant is THC most concentrated?
Leaves
Seeds
Buds
Roots
THC is produced in the resinous trichomes that are most abundant on the flowering buds of the cannabis plant. While leaves have some trichomes, they are far more concentrated on the buds. Seeds and roots contain almost no THC.
Which U.S. state was the first to legalize recreational cannabis?
California
Washington
Colorado
Oregon
Voters in Colorado approved Amendment 64 in November 2012, making it the first U.S. state to legalize adult-use recreational cannabis. Retail sales began in January 2014. Washington also approved recreational use in 2012, but Colorado's Amendment is widely cited as the first.
What does THC stand for?
Tetrahydrocannabinol
Tetrahydrocathinol
Tetrahydrocannabinane
Tetrahydrocanabinene
THC is short for delta-9-tetrahydrocannabinol, the primary psychoactive compound in cannabis. Its chemical structure distinguishes it from other cannabinoids like CBD. The name reflects its molecular components: a tetrahydro ring attached to a cannabinol backbone.
Which method of cannabis consumption provides the fastest onset of effects?
Inhalation (smoking or vaping)
Sublingual drops
Oral ingestion
Topical application
Inhalation delivers cannabinoids directly into the bloodstream through the lungs, producing noticeable effects within minutes. Oral ingestion (edibles) can take 30 - 90 minutes, and sublingual or topical methods vary based on formulation. For immediate relief or rapid onset, inhalation is preferred.
What is the typical THC potency range for most recreational cannabis strains?
5 - 10%
15 - 25%
25 - 35%
10 - 15%
Most modern recreational cannabis flower falls within the 15 - 25% THC range, though specialty strains can exceed that. Earlier generations of cannabis averaged lower potency. Consumers often choose based on tolerance and desired effects.
What does CBD stand for?
Cannabicyclol
Cannabinol
Cannabidiol
Cannabidinol
CBD is short for cannabidiol, one of the major non-psychoactive cannabinoids found in cannabis. It has been studied for its potential therapeutic benefits, including anxiety and pain relief. Cannabinol (CBN) and cannabicyclol (CBL) are different, less abundant cannabinoids.
Under the U.S. Controlled Substances Act, marijuana is classified as which schedule?
Schedule IV
Schedule II
Schedule I
Schedule III
Marijuana is listed as a Schedule I substance, defined as having no accepted medical use and a high potential for abuse. This classification is controversial given its medical applications. Schedule II substances like oxycodone have recognized medical uses but still high abuse potential.
Which terpene is primarily responsible for the citrus aroma in many cannabis strains?
Pinene
Linalool
Limonene
Myrcene
Limonene is a common terpene found in citrus fruits and many cannabis strains, giving them a lemony, fresh aroma. Myrcene smells more earthy or musky, pinene is pine-like, and linalool smells floral or lavender-like. Terpenes contribute to the overall cannabis experience.
Which U.S. President signed the Marihuana Tax Act of 1937 into law?
Franklin D. Roosevelt
Herbert Hoover
Dwight D. Eisenhower
Harry S. Truman
President Franklin D. Roosevelt signed the Marihuana Tax Act in 1937, which imposed a tax on the sale of cannabis and effectively criminalized its use. The act was influenced by political and racial factors of the era. It remained in effect until it was overturned in 1969.
In which year did Canada legalize recreational cannabis nationwide?
2018
2019
2017
2016
Canada's Cannabis Act took effect on October 17, 2018, making it the second country and first G7 nation to legalize recreational cannabis at the federal level. Medical cannabis had been legal since 2001. The 2018 law regulates production, distribution, and possession.
Which of these is NOT a typical cannabis consumption method?
Sublingual
Intravenous injection
Topical
Inhalation
Cannabis is commonly inhaled, taken orally (edibles), applied topically, or administered sublingually. Intravenous injection of cannabis is not a recognized or safe method of consumption. Infusing THC into a solution suitable for injection poses extreme health risks.
What does the 'entourage effect' refer to in cannabis science?
The effect of cannabis on muscle growth
The agricultural yield of plants
Synergistic interaction among cannabinoids and terpenes
The psychoactive trip from pure THC
The entourage effect is the theory that cannabinoids, terpenes, and other compounds in cannabis work synergistically to enhance therapeutic benefits. This concept suggests full-spectrum extracts may be more effective than isolates. Research is ongoing to understand the mechanisms involved.
Which process converts THCA into the psychoactive THC compound?
Polymerization
Oxidation
Isomerization
Decarboxylation
THCA (tetrahydrocannabinolic acid) converts to psychoactive THC when heated in a process called decarboxylation, which removes a carboxyl group. This occurs during smoking, vaping, or when making edibles. Without decarboxylation, THCA remains non-psychoactive.
High-CBD, low-THC cannabis varieties are commonly known as what?
Hemp
Ganja
Kief
Resin
Hemp is defined by law in many regions as cannabis containing less than 0.3% THC and higher levels of CBD. It's grown industrially for fiber, seeds, and CBD extraction. Ganja typically refers to psychoactive cannabis. Resin and kief are concentrated trichomes.
Which minor cannabinoid, known as the 'mother of all cannabinoids', is a precursor to THC and CBD?
CBC (cannabichromene)
CBN (cannabinol)
THCV (tetrahydrocannabivarin)
CBG (cannabigerol)
Cannabigerol (CBG) is often called the 'mother cannabinoid' because it forms in the plant as CBGA and then converts via enzymes into precursor molecules for THC (THCA), CBD (CBDA), and CBC (CBCA). It's typically present in low concentrations in mature plants.
Which endocannabinoid receptor is predominantly found in the immune system?
CB1
TRPV1
GABA_A
CB2
The CB2 receptor is primarily expressed in immune cells and peripheral tissues, playing a role in modulating inflammation and immune response. CB1 receptors are more concentrated in the central nervous system. TRPV1 and GABA_A are different receptor families.
What is 'cannabutter' typically used for?
Baking and edibles
Smoking in pipes
Mixing with beverages
Topical skin ointments
Cannabutter is butter infused with cannabinoids, most commonly used as a base for edible recipes like brownies, cookies, and other baked goods. It allows for consistent dosing and easy incorporation into various dishes. It is not designed for smoking or topical use.
Which U.S. state was the first to decriminalize small amounts of cannabis in 1973?
California
New York
Colorado
Oregon
Oregon was the first U.S. state to decriminalize the possession of small amounts of cannabis in 1973, replacing criminal penalties with a fine. This policy shift influenced other states and contributed to the modern reform movement. California followed suit in 1975.
What is 'kief' in the context of cannabis?
A cannabis disease
A type of edible
A crossbreed strain
A concentration of trichome crystals
Kief consists of the resinous trichome glands that fall off cannabis buds during handling. It's a potent concentrate often used in joints, sprinkled on bowls, or pressed into hash. Kief is prized for its high cannabinoid and terpene content.
Which cannabinoid was approved in the prescription medication Epidiolex for epilepsy treatment?
THC
THCA
CBN
CBD
Epidiolex is an FDA-approved prescription medication containing purified cannabidiol (CBD) for the treatment of two rare forms of epilepsy. It does not contain THC, avoiding psychoactive effects. This marks the first cannabis-derived drug approved by the FDA.
What is the approximate molecular weight of THC (tetrahydrocannabinol)?
314.47 g/mol
414.52 g/mol
150.25 g/mol
244.31 g/mol
The molecular weight of delta-9-tetrahydrocannabinol (THC) is approximately 314.47 grams per mole. This is calculated based on its chemical formula C??H??O?. Precise molecular weight is essential for dosage and formulation in pharmaceutical applications.
During the flowering stage, which light spectrum is most effective for maximizing cannabis bud production?
Red light around 660 nm
UV light around 380 nm
Green light around 550 nm
Blue light around 450 nm
Red light at approximately 660 nm promotes flowering and bud development in cannabis by stimulating phytochrome receptors. Blue light is more important during vegetative growth. Green and UV can contribute to overall health but are less central to flowering efficacy.
In cannabis breeding, the term 'F1 hybrid' refers to what?
A genetically identical clone
A parental line
The first filial generation from two distinct parent strains
A strain created by backcrossing
An F1 hybrid is the first-generation offspring of two genetically distinct parent strains, often exhibiting hybrid vigor and consistent traits. Breeders use F1 hybrids to combine desired characteristics like yield, potency, and pest resistance. Subsequent generations (F2, F3) can show more genetic variability.

Cheat Sheet

  1. Botanical Basics: Sativa vs. Indica Distinctions -

    Review the morphological traits and growth patterns that distinguish Cannabis sativa from Cannabis indica as outlined by university agricultural extensions like UC Davis. Remember the mnemonic "Sativa Stands Tall, Indica Is Inward" to recall that sativas grow taller with narrow leaves and energizing effects, while indicas are bushier with broader leaves and calming profiles. Focus on photosynthetic pathways (C3 vs. C4) and flowering times for a quick recall during trivia.

  2. Cannabinoid Chemistry: THC vs. CBD -

    Memorize the molecular formulas (THC: C21H30O2; CBD: C21H30O2) and how their structural isomers bind differently to CB1 receptors according to studies from the Journal of the American Chemical Society. Use the phrase "THC Thrills, CBD Calms" to quickly distinguish psychoactive effects versus therapeutic uses. Recognize that slight atomic arrangements lead to major impact differences in receptor affinity and resultant effects.

  3. Endocannabinoid System Receptors -

    Understand CB1 and CB2 receptor distribution - "1 Brain, 2 Body" - a mnemonic indicating CB1's prevalence in the central nervous system and CB2's in peripheral tissues like the immune system, per NIH data. Recall how endocannabinoids like anandamide interact with these receptors to regulate mood, appetite, and pain. Knowing receptor locations is key for answering questions on pharmacological action and therapeutic potential.

  4. Historical & Legal Milestones -

    Track pivotal legalization dates - from the first medical cannabis law in California (1996) to Canada's nationwide legalization in 2018 - via government archives and WHO reports. Create a timeline acronym "CA96-CO12-CA18" for California's Prop 215, Colorado recreational legal in 2012, and Canada Cannabis Act 2018. This helps quickly recall landmark events and their impact on global cannabis policy shifts.

  5. Consumption Methods & Pharmacokinetics -

    Compare bioavailability and onset: inhalation (50 - 60% bioavailability, 5 - 10 min onset) versus oral edibles (10 - 20% bioavailability, 30 - 90 min onset), according to NIDA research. Mnemonic "Smoke Fast, Edibles Last" aids in remembering these timelines and absorption rates. Understanding these differences ensures accurate responses on quiz questions about dosing and effect duration.
