Q&A

Quick Answer: What Is Cannabis?

Cannabis is a flowering plant whose dried buds (flower) and extracts contain dozens of pharmacologically active compounds, most prominently THC (delta-9-tetrahydrocannabinol - the primary psychoactive cannabinoid) and CBD (cannabidiol - non-psychoactive, with anti-inflammatory and anxiolytic effects). Cannabis is consumed by smoking, vaporizing, eating (edibles), drinking (beverages), holding under the tongue (tinctures), or applying to skin (topicals). In Nevada, adults 21 and older can legally purchase up to 2.5 ounces of flower or 1/4 ounce (0.25 oz) of concentrate per transaction at a state-licensed dispensary, possess that amount in private, and consume only on private residential property with the property owner's consent. Cannabis remains federally illegal as a Schedule I substance, which is why dispensary cannabis cannot be transported across state lines, possessed on federal land, or brought onto a commercial flight. All Greenleaf products are from Nevada-licensed manufacturers and tested under Nevada Cannabis Compliance Board rules for potency, residual solvents, pesticides, microbials, and heavy metals.

02 · The Major Cannabinoids

The Major Cannabinoids

Cannabis produces roughly 100 cannabinoids, but a handful do most of the work:

THC (delta-9-tetrahydrocannabinol): The primary psychoactive cannabinoid. Produces the "high" - euphoria, altered perception, increased appetite, drowsiness or alertness depending on the cultivar. Researchers have studied THC in connection with pain, nausea, and appetite; these statements have not been evaluated by the FDA and are not medical advice - consult a licensed provider.
CBD (cannabidiol): Non-psychoactive. Studied for possible anti-inflammatory and calming properties; not FDA-evaluated, not medical advice. Often paired with THC to "soften" the high. See THC vs CBD.
CBN (cannabinol): Mildly psychoactive degradation product of THC. Strongly associated with sleep effects in product marketing; the science is less settled than the marketing suggests.
CBG (cannabigerol): Non-psychoactive precursor to THC and CBD. Anti-inflammatory; emerging research interest.
THCa (tetrahydrocannabinolic acid): The acidic form of THC in raw cannabis. Non-psychoactive until heated (decarboxylated), at which point it converts to THC. THCa diamonds are the highest-potency concentrate format.
Delta-8-THC: A minor cannabinoid; psychoactive but less potent than delta-9. Most "delta-8" products on the market are hemp-derived synthesized; product quality varies.

03 · Terpenes (And Why They Matter)

Terpenes (And Why They Matter)

Terpenes are aromatic compounds produced by cannabis (and many plants) that contribute to flavor, aroma, and modulate cannabinoid effects via the entourage effect. Common terpenes you'll see called out on Greenleaf product labels:

Terpene content frequently predicts effect better than the THC percentage. A 18% THC flower with a heavy myrcene-linalool profile will hit very differently from a 18% THC flower with a pinene-limonene profile.

Myrcene - earthy, fruity; often associated with sedative/relaxing effects (the "couch lock" terpene)
Limonene - citrus; often associated with mood elevation
Pinene - pine; often associated with alertness, focus
Linalool - floral/lavender; often associated with calming effects
Caryophyllene - peppery; the only terpene that interacts with CB2 receptors
Terpinolene - fruity/floral; often associated with sativa-leaning energetic effects
Humulene - hoppy; often associated with appetite suppression

04 · Indica vs Sativa vs Hybrid

Indica vs Sativa vs Hybrid

The traditional categorization of cannabis cultivars:

The indica/sativa binary is increasingly seen as marketing shorthand rather than precise pharmacology. Modern cannabis science emphasizes terpene profiles and specific cannabinoid ratios over the indica/sativa label. Read indica vs sativa for the deeper breakdown.

Indica: Generally body-heavy, sedative, evening, sleep, pain. Stereotypical examples: Granddaddy Purple, Bubba Kush, Northern Lights.
Sativa: Generally head-forward, energizing, daytime, focus, creativity. Stereotypical examples: Sour Diesel, Jack Herer, Durban Poison.
Hybrid: Cross of indica and sativa lineage. The vast majority of modern cultivars are hybrids leaning indica or sativa.

06 · Dosing Basics: Start Low, Go Slow

Dosing Basics: Start Low, Go Slow

The single most important rule for new and returning consumers:

For inhaled cannabis (flower, pre-rolls, vapes, dabs): One puff, wait 5 minutes, reassess. Effects start within seconds and peak around 15-30 minutes. The mistake first-timers make is taking too many puffs before effects kick in.

For edibles and beverages: Start with 2.5-5mg of THC. Wait at least 90 minutes before taking more. Edibles convert to 11-hydroxy-THC in the liver, which is more potent and longer-lasting than inhaled delta-9-THC. The mistake first-timers make is "it's not working" at 60 minutes and re-dosing - then 30 minutes later they're vastly over-medicated for several hours.

For tinctures: Start at 5-10mg sublingual. Hold under the tongue for 60-90 seconds. Effects faster than swallowed edibles, slower than inhaled. See tinctures hub.

For topicals: No dosing concern for standard topicals (no high).

Section 07

What Happens When You Consume Too Much

A "greenout" - taking too much cannabis at once - typically presents as anxiety, paranoia, increased heart rate, dry mouth, dizziness, sometimes nausea. It's uncomfortable but not medically dangerous in healthy adults. The standard harm-reduction response: stay calm, drink water, eat something, find a quiet/comfortable space, sleep it off. CBD can sometimes counteract the effects of too much THC. Effects from inhaled cannabis pass within 1-3 hours; effects from edibles can take 6-12 hours to fully clear.

If symptoms are severe (chest pain, vomiting, severe distress) or the consumer is a child or pet, seek medical attention. Cannabis is not lethal in oral doses anywhere near what a human could consume, but pets - especially dogs - can suffer serious THC toxicity. Read edibles harm reduction and Nevada Poison Control resources if needed.

08 · Buying Cannabis Legally in Nevada

Buying Cannabis Legally in Nevada

To purchase at any Nevada dispensary including Greenleaf:

Read Nevada cannabis laws for the full regulatory framework, first-time visiting a dispensary in NV for what to expect at the counter, and how to get a Nevada medical card if you have a qualifying condition.

Be 21+ with a valid government photo ID (driver's license, state ID, passport)
Out-of-state IDs are accepted. Nevada does not require Nevada residency.
Cash is preferred at most dispensaries due to federal banking restrictions; debit and ATM-on-premises are increasingly common
Single-transaction caps: 2.5 oz flower or 1/4 oz (0.25 oz) concentrate
Possession caps: Same 2.5 oz flower / 0.25 oz concentrate limit applies
Medical card accepted: Nevada honors medical cards from other states; medical patients may qualify for higher transaction limits and tax advantages

09 · Lab Testing

Lab Testing: What "Tested" Means

Every product on a Nevada dispensary shelf has a current Certificate of Analysis (COA) from a state-licensed testing lab. Tests cover:

We can pull the COA for any SKU at the counter or by request before purchase. The unlicensed market has no testing requirements; cheap "street" cannabis often contains pesticides, heavy metals, or mold that licensed product is screened for.

Potency - THC, CBD, total cannabinoids
Residual solvents - for solvent-extracted products (BHO, distillate)
Pesticides - chemical screen
Microbials - mold, yeast, E. coli, salmonella
Mycotoxins - fungal toxins
Heavy metals - lead, arsenic, cadmium, mercury

10 · Cannabis 101 FAQ

Cannabis 101 FAQ

Will cannabis show up on a drug test? Yes. THC metabolites (THC-COOH) can be detected in urine for 3-30+ days depending on consumption frequency, body composition, and test sensitivity. CBD-only products with no THC are less likely to trigger positives, but cross-contamination is possible.

Is cannabis addictive? Cannabis use disorder is recognized in the DSM-5. Roughly 9% of regular consumers develop a cannabis use disorder; that rate climbs higher for those who start consuming in adolescence. Daily heavy use is the strongest predictor of dependence.

Can I drive after consuming? No. Driving impaired is illegal in Nevada and dangerous. Effects from inhaled cannabis can persist 2-4 hours; edibles longer.

Is "indica = nighttime, sativa = daytime" actually true? Sometimes. Terpene profiles are a better predictor than the indica/sativa label. See indica vs sativa.

Where can I consume legally in Nevada? Private residential property only with property-owner consent. Not casinos, hotels (most), public spaces, vehicles, federal land, or non-cannabis-permissive Airbnbs.

What's the highest-THC flower you carry? Greenleaf rotates flower in the 22-32% THC range. See flower hub and concentrates hub.

What's the safest format for first-timers? Most experienced budtenders point first-timers toward low-dose edibles (2.5-5mg) or tinctures for predictable, controllable dosing. Pre-rolls are fine if you're already comfortable with smoking; just take one puff and wait.

--- For use only by adults 21 years of age or older. Keep Out of Reach of Children. Cannabis is federally illegal as a Schedule I substance and cannot cross state lines. Consume on private residential property only. Keep cannabis and pets separated. Do not drive after consuming.
