The world of cannabis is diverse, with various classifications used to describe its different types, effects, and compositions. Understanding these categories is essential for consumers, researchers, and cultivators.

Species Classification

The most common way to classify cannabis is by its species, which are generally recognized as having distinct physical characteristics and effects.

Classification	Appearance	Key Characteristics
Cannabis Sativa	Tall, slender plants with narrow leaves	Often associated with an energizing, "head high"
Cannabis Indica	Short, bushy plants with broad leaves	Typically associated with a relaxing, "body high"
Cannabis Ruderalis	Small, low-growing plants	Naturally auto-flowering, very low THC content
Hybrid	A cross between two or more species	Effects and appearance vary widely based on parent strains

Chemotype (Cannabinoid Profile) Classification

Cannabis can also be classified by its chemical composition, specifically the ratio and concentration of major cannabinoids, such as Tetrahydrocannabinol (THC) and Cannabidiol (CBD). This is often considered a more accurate predictor of effects than species classification.

The Four Major Chemotypes

1. Type I: THC-Dominant
   • Description: High levels of THC, low levels of CBD.
   • Effect Focus: Psychoactive and intoxicating effects.
2. Type II: Balanced THC/CBD
   • Description: Significant levels of both THC and CBD.
   • Effect Focus: A mix of psychoactive and therapeutic effects, often less intense than Type I.
3. Type III: CBD-Dominant (Hemp)
   • Description: High levels of CBD, very low levels of THC (often below 0.3%).
   • Effect Focus: Non-intoxicating therapeutic effects.
4. Type IV: CBG-Dominant
   • Description: High in Cannabigerol (CBG). These strains are still rare.
   • Effect Focus: Research into therapeutic potential is ongoing.

Consumption Method Classification

While not a classification of the plant itself, how cannabis is prepared and consumed leads to different product classifications.

• Flower (Bud): Dried and cured cannabis plant material, typically smoked or vaporized.
• Concentrates: Products made by extracting cannabinoids and terpenes from the plant material, resulting in a highly potent product (e.g., shatter, wax, oil).
• Edibles: Food or drink infused with cannabis extracts. Effects take longer to onset but can last much longer.
• Topicals: Creams, balms, or lotions infused with cannabinoids for localized, non-psychoactive relief.
