Beginner's Guide to Cannabis

New to cannabis, or just looking to refresh the fundamentals? This guide covers strain types, cannabinoids, terpenes, product categories, consumption methods, and dosing — everything you need to shop and use cannabis with confidence.

What is Cannabis?

Cannabis is a flowering plant that produces hundreds of unique compounds — most notably cannabinoids and terpenes — that interact with the body's endocannabinoid system to produce a range of psychoactive and therapeutic effects. People use it recreationally to relax, lift mood, or socialize, and medicinally to support sleep, manage pain, ease anxiety, and more.

Understanding Cannabinoids

Cannabinoids are the active compounds in cannabis. THC and CBD get the headlines, but there are over 100 — and each plays a different role in how a product feels.

THCTetrahydrocannabinol

The main psychoactive compound in cannabis — responsible for the classic euphoria, altered perception, and head/body high.

PsychoactiveYes
Often feels likeEuphoric, heady, body high
CBDCannabidiol

Non-intoxicating and widely used for calm and relief. Often paired with THC to balance and soften its effects.

PsychoactiveNo
Often feels likeCalm, soothing, clear-headed
CBGCannabigerol

The “mother cannabinoid” other compounds derive from. Often associated with focus and a clear-headed mood.

PsychoactiveNo
Often feels likeFocused, light, alert
CBNCannabinol

Formed as THC ages. Frequently found in sleep-focused products and often paired with indica strains.

PsychoactiveMild
Often feels likeSedated, heavy, sleepy
THCVTetrahydrocannabivarin

A lighter, more cerebral psychoactive compound sometimes called “diet weed.” Often associated with appetite suppression, focus, and clear-headed energy.

PsychoactiveMild
Often feels likeEnergetic, focused, light
CBCCannabichromene

A non-intoxicating minor cannabinoid often included in full-spectrum products for its supportive role in the entourage effect.

PsychoactiveNo
Often feels likeMellow, supportive
THCaTetrahydrocannabinolic Acid

The raw, non-psychoactive precursor to THC. Converts to THC when heated (smoked, vaped, or cooked).

PsychoactiveNo
Often feels likeNon-intoxicating (raw form)
Δ8-THCDelta-8 THC

A milder, smoother cousin of Δ9-THC. Produces a clearer, lower-intensity high — often described as halfway between THC and CBD.

PsychoactiveMild
Often feels likeMellow, relaxed, lightly euphoric
CBDaCannabidiolic Acid

The raw, non-psychoactive form of CBD found in fresh cannabis. Converts to CBD when heated and is sometimes featured in tinctures and topicals.

PsychoactiveNo
Often feels likeCalm, soothing (raw form)

These compounds have not been evaluated by the FDA as treatments for any condition, and effects vary by person, dose, and product.Source: National Academies of Sciences, Engineering, and Medicine (2017). The Health Effects of Cannabis and Cannabinoids.

Understanding Terpenes

Terpenes are the aromatic oils that give each strain its smell and personality. There are over 200 known terpenes identified in the cannabis plant — here are the primary ones.

Myrcene

One of the most abundant terpenes in cannabis. Known for earthy, musky, sometimes fruity aromas and potential anti-inflammatory and sedative effects.

AromaEarthy, herbal, ripe mango
EffectsRelaxing, sedating, calming
Also found inMango, hops, lemongrass
Limonene

The second most common terpene in nature, abundant in citrus peel. Promotes relaxation, boosts mood, eases nervousness, and acts as a strong antioxidant.

AromaBright citrus, lemon zest
EffectsUplifting, mood-boosting
Also found inLemon and orange peel
Caryophyllene

A spicy, pepper-scented terpene that uniquely interacts with the body's endocannabinoid system — often associated with muscle relaxation, reduced stress, and better sleep.

AromaPeppery, spicy, woody
EffectsSoothing, comforting
Also found inBlack pepper, cloves, cinnamon
Pinene (α & β)

The most abundant terpene in nature, rich in evergreen trees and herbs. Often associated with supporting respiratory function and short-term memory.

AromaFresh pine, rosemary
EffectsAlert, focused, clear-headed
Also found inPine needles, basil, rosemary
Linalool

The signature floral terpene of lavender. Widely associated with a calming, restful effect and may help ease nervousness and tension.

AromaFloral, lavender, sweet
EffectsCalming, blissful, restful
Also found inLavender, mint
Humulene

A hoppy terpene with earthy, spicy notes. Common in hops, coriander, and basil — may offer anti-inflammatory effects and help with discomfort and appetite control.

AromaEarthy, hoppy, woody
EffectsMellow, grounding
Also found inHops, sage, ginseng

Disclaimer: Terpene effects in cannabis are an active area of research. The ‘entourage effect’ — the idea that cannabinoids and terpenes work better together — is a working hypothesis with growing but still incomplete evidence. Treat these as general aromatic and folk-effect associations, not clinical claims.Sources: Russo (2011), Br J Pharmacol; LaVigne et al. (2021), Cannabis sativa terpenes are cannabimimetic, Scientific Reports.

Understanding Dosages

Especially with edibles — wait at least 2 hours before taking more. These ranges are general guidelines for THC; everyone’s body is different.

🟢 New / Sensitive

Microdose territory. Best for first-timers, sensitive folks, or wellness-only use without much of a head change.

Dose1–2.5 mg
LevelMicrodose
🟡 Casual

Mild to moderate euphoria. A good weekend or evening dose for occasional users.

Dose2.5–10 mg
LevelMild
🟠 Regular User

Strong, full effects. For experienced users with some tolerance built up.

Dose10–25 mg
LevelStrong
🔴 High Tolerance

Daily users with significant built-up tolerance. Listen to your body — more isn't always more.

Dose25 mg+
LevelHeavy

How potency is labeled

Strength shows up two different ways on a label, depending on the type of product.

THC %
Flower & concentrates

The share of the product's weight that's THC. Flower typically tests 18–30%; concentrates like vapes, wax, and rosin run 60–90%. A higher percentage means more THC per gram — but terpenes and your own tolerance shape the experience just as much as the number.

Milligrams (mg)
Edibles, drinks & tinctures

These aren't measured by weight — they're labeled in milligrams of THC. A package shows the total (e.g. 100mg) and the dose per piece (e.g. 10mg each). In California a package caps at 100mg, with 10mg per serving.

Important: These are general guidelines for THC, not medical advice. Cannabis affects everyone differently — start at the lower end of any range, wait the full onset window, and adjust slowly. Don't combine with alcohol or operate machinery while impaired. If you're pregnant, nursing, taking prescription medication, or managing a medical condition, talk to your doctor before using cannabis.Source: MacCallum & Russo (2018), Practical considerations in medical cannabis administration and dosing.

Understanding Consumption Methods

Onset, duration, and intensity depend on how you consume cannabis. Pick the method that matches the experience you want.

Smoking / Vaping

Inhaling cannabis flower or vapor. The classic method — immediate effects and easy dose control by the puff. Joints, pipes, bongs, and vape carts all fall here.

Onset0–5 min
Duration1–3 hrs
Dabbing

Vaporizing cannabis concentrates like live resin, rosin, or sauce at high temperatures. Extremely potent and fast-acting — best for experienced users.

Onset0–5 min
Duration1–3 hrs
Edibles

Cannabis-infused gummies, chocolates, and baked goods. Long-lasting and smoke-free, but slow to kick in. Start low, go slow.

Onset30–120 min
Duration4–8 hrs
Beverages

Cannabis-infused drinks like seltzers, teas, and tonics. Modern nano-emulsified beverages kick in faster than traditional edibles and offer pre-measured doses.

Onset15–45 min
Duration2–6 hrs
Tinctures

Liquid cannabis dosed by the dropper. Held under the tongue for faster onset, or added to food/drinks for an edible-like experience. Very precise dosing.

Onset15–45 min
Duration2–6 hrs
Topicals

Creams, balms, lotions, and roll-ons applied to the skin. Targeted, localized relief without the head high (most non-transdermal topicals are non-intoxicating).

Onset15–30 min
Duration2–4 hrs

Disclaimer: Onset and duration are general averages. Individual factors — body composition, recent meals, metabolism, tolerance, and product potency — can shift these ranges significantly. Inhaled methods deliver THC faster but for a shorter window than ingested methods.Source: MacCallum, C. A. & Russo, E. B. (2018).

Explore Our Categories

Every category does something a little different. Here’s a quick tour of what’s on the menu and how to use it.

Note: Potency, formulation, and effects vary across brands and batches. Always check a product's lab results and label before consuming, especially when trying something new.

What to expect your first time

A few things worth knowing if cannabis is new to you. Take it slow, be kind to yourself, and remember — whatever you feel always passes.

What to expect

A pleasant warmth, shifted time perception, possible giggles or thoughtfulness, heightened senses or appetite. Effects build for the first 20–60 minutes (longer for edibles). If it feels strong, it always passes — you'll be back to yourself in a few hours.

Start low, go slow

Begin with 1–2.5 mg of THC, especially with edibles, and wait the full onset window before considering more. The classic rule: you can always take more, but you can't take less.

Set & setting

Pick a calm, familiar place with trusted company on a low-key day. Your mood and environment going in shape the experience as much as the dose. A first time isn't the moment for big plans or stressful situations.

Common misconceptions

Higher THC% doesn't automatically mean a better experience — terpenes and cannabinoid balance matter just as much. And you can't fatally overdose on cannabis, but you can absolutely have an uncomfortable few hours if you take too much.

Safety basics

Don't drive, operate machinery, or sign anything important while impaired. Skip mixing with alcohol or other substances on your first try. Stay hydrated. If you take prescription meds or are pregnant/nursing, talk to your doctor first.

How to store it

Cool, dark, airtight. Flower and concentrates lose potency and flavor with heat, light, and air exposure — glass jars beat plastic bags. Always store out of reach of children and pets, ideally in a locked container.
