Cannabis Oil: Uses Benefits and Applications 2025

Cannabis oil, also known as cannabis extract, marijuana oil, or hemp oil (when derived from low-THC plants), is a concentrated liquid containing cannabinoids extracted from the Cannabis sativa plant.

It encompasses a wide range of products distinguished by extraction method, cannabinoid profile, and intended use — from full-spectrum oils rich in THC and CBD to isolated CBD tinctures. In 2025, cannabis oils dominate the wellness and medical cannabis markets, valued globally at over USD 20 billion and growing rapidly due to legalization, consumer preference for discreet consumption, and therapeutic applications.

Types of Cannabis Oil

Cannabis Oils are classified by spectrum and primary cannabinoid:

Full-Spectrum: Contains all plant compounds (THC, CBD, minor cannabinoids, terpenes, flavonoids) — maximizes “entourage effect.”
Broad-Spectrum: THC removed, retains other compounds.
CBD Isolate: Pure CBD only (>99% purity).
Rick Simpson Oil (RSO): High-THC full-spectrum extract, traditionally made with naphtha solvent.
Hemp Seed Oil: Cold-pressed from seeds; contains no cannabinoids — often confused with CBD oil.

Extraction Methods

Quality and safety depend heavily on extraction technique:

CO₂ Extraction: Supercritical CO₂ — clean, efficient, preserves terpenes; industry gold standard.
Ethanol Extraction: Food-grade alcohol; effective for full-spectrum but may extract chlorophyll.
Hydrocarbon Extraction (butane/propane): Produces live resin/rosin; high potency but requires strict purging.
Rosin Press: Solventless heat/pressure method — popular among purists.
Olive Oil Infusion: Home method; low potency, short shelf life.

Chemical Composition

Primary active compounds:

Δ9-THC: Psychoactive.
CBD: Non-psychoactive, anti-inflammatory, anxiolytic.
Minor Cannabinoids: CBG, CBN, CBC, THCV.
Terpenes: Myrcene, limonene, pinene, linalool — aroma and therapeutic synergy.

Consumption Methods

Sublingual: Drops under tongue — fast onset (15-45 min).
Oral: Swallowed or added to food — slower onset (1-2 hours), longer duration.
Vaping: Inhaled via vape cartridges — immediate effect.
Topical: Applied to skin for localized relief.
Capsules: Precise dosing.
