Medical cannabis, also known as medical marijuana, contains active compounds called cannabinoids that interact with the body’s endocannabinoid system. As cannabis plants grow, cure, and age, cannabinoids naturally transform into different compounds, creating a wide range of therapeutic effects.

The most researched and commonly used cannabinoids include:

• THC (Tetrahydrocannabinol) – Known for psychoactive effects, pain relief, and relaxation

• CBD (Cannabidiol) – Non-intoxicating, commonly used for anxiety, inflammation, and overall wellness

• CBG (Cannabigerol)

• CBC (Cannabichromene)

• CBN (Cannabinol)

• THCV (Tetrahydrocannabivarin)

While dozens of cannabinoids have been identified, THC and CBD remain the most widely used in medical cannabis treatment plans.

How Medical Cannabis Works in the Body

Cannabinoids interact primarily with CB1 and CB2 receptors in the body:

• CB1 receptors are located mainly in the brain and central nervous system.

• CB2 receptors are found mostly in the immune system and peripheral tissues.

THC binds directly to CB1 receptors, which explains its psychoactive effects along with its ability to support pain relief, appetite stimulation, and relaxation.

CBD works differently. It does not bind strongly to CB1 or CB2 receptors but instead influences how other cannabinoids interact with them. CBD may help balance the effects of THC, potentially reducing unwanted side effects like anxiety or paranoia.

Over time, THC naturally converts into CBN, which is often associated with calming and sleep-supporting effects.

THC vs CBD: What’s the Difference?

When comparing THC vs CBD, the main difference is psychoactivity. THC produces a “high,” while CBD does not. However, both compounds are studied for potential benefits such as:

• Chronic pain management

• Anxiety relief

• Inflammation support

• Sleep improvement

• Appetite regulation

Many medical cannabis products combine THC and CBD to create balanced cannabinoid profiles tailored to individual needs.

Sativa vs Indica: Do Strains Matter?

Cannabis strains are often categorized as sativa, indica, or hybrid, though the true effects depend more on cannabinoid ratios and terpene profiles than the label itself.

• Indica strains are commonly associated with relaxation and nighttime use.

• Sativa strains are often described as uplifting and energizing.

• Hybrid strains combine characteristics of both.

Modern research suggests that cannabinoid content and terpene composition play a greater role in determining effects than strain name alone.

Emerging Cannabinoids: THCV & Beyond

Compounds like THCV (tetrahydrocannabivarin) are gaining attention for potential benefits including appetite control, metabolic support, and possible anxiety reduction. Unlike THC, THCV may produce different or milder psychoactive effects depending on dosage.

Ongoing research continues to explore additional receptors, such as GPR55 and 5-HT1A, which may explain the diverse therapeutic potential of cannabis compounds.
