Understanding Cannabis and Cannabinoids

Cannabis and cannabinoids are compounds found in the cannabis plant, with over 100 different cannabinoids identified. These include tetrahydrocannabinol (THC) and cannabidiol (CBD), which have distinct properties and effects on the body.

Constituents of cannabis

Cannabis has many parts that work in different ways. It's not just one thing; it’s made up of lots of compounds.

THC (tetrahydrocannabinol): This part makes people feel high. It can also help control pain and nausea.
CBD (cannabidiol): CBD doesn't make you feel high. Studies show it may slow cancer cell growth and help with pain without the mind-altering effects.
Terpenes: These give cannabis its smell. Some believe they may also help with health problems.
Flavonoids: They are found in all kinds of plants. In cannabis, flavonoids might have their own health benefits.
Cannabinol (CBN): This is made when THC gets old. It might help you sleep better.
Tetrahydrocannabivarin (THCV): Like THC, it can affect your mind but it acts a bit differently.
Cannabichromene (CBC): Not as well-known, but it could have important effects we're starting to learn about.

Cultivars of cannabis

Moving from the different parts that make up cannabis, let's explore the various types of the plant itself. Cannabis can be grown in many forms and these are known as cultivars. Here is a detailed look at some popular cultivars:

Sativa: Plants from this group are tall and thin with finger-like leaves. They grow best in warm climates. People use Sativa to feel more active and creative.
Indica: These plants are shorter and bushier than Sativa. Their leaves are wider. Indica is often used to help with sleep and to relax muscles.
Ruderalis: This type is smaller and can grow in harsher conditions. It isn't used much on its own because it has less THC, which is the part that makes you feel high.
Hybrids: Growers mix different types of cannabis to make hybrids. These new kinds can have qualities from both parents or be bred for specific effects.

Differences between THC and CBD

THC and CBD are both important parts of the cannabis plant. THC, or delta-9-tetrahydrocannabinol, is what makes people feel high. It fits into receptors in the brain and changes how we think, feel, and act.

CBD doesn't do that. Instead, it interacts with other parts of the body and might help with health issues without making you feel out of sorts.

CBD can help your body in many ways while keeping your mind clear. Unlike THC, CBD will not cause any mind-altering effects but may still offer medical benefits to help with different symptoms.

These differences mean that CBD could be a helpful part of treating cancer without giving patients the psychoactive experience tied to marijuana use.

The Endocannabinoid System and its Role in Cancer

The endocannabinoid system consists of cannabinoid receptors and molecules that play a crucial role in regulating various physiological processes, including those related to cancer development and progression.

Understanding the components and functioning of this system can shed light on how CBD may impact cancer treatment.

Components of the endocannabinoid system

The endocannabinoid system consists of three main components which play crucial roles in regulating various physiological processes and maintaining balance within the body. These components include:

Endocannabinoids: They are lipid signaling molecules that bind to cannabinoid receptors, helping to regulate neurotransmitter release in the brain.
Cannabinoid Receptors (CB1 and CB2): These receptors are located throughout the body, with CB1 predominantly found in the central nervous system and CB2 primarily in immune cells. They are responsible for mediating the effects of cannabinoids.
Metabolic Enzymes: Enzymes such as fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL) are involved in the synthesis and degradation of endocannabinoids, thus influencing their levels in the body.

Location of CB1 and CB2 receptors

CB1 and CB2 receptors are found in the human body. The CB1 receptor is mostly in the brain, while the CB2 receptor is mainly in the immune system and other peripheral tissues. These receptors play a crucial role in how our body responds to cannabis compounds like CBD.

In summary, CB1 and CB2 receptors have distinct locations within our bodies, with one primarily located in the brain and the other predominantly situated in the immune system and peripheral tissues.

How the endocannabinoid system works

Now, let's dive into understanding how the endocannabinoid system works. This intricate system consists of three main components: endocannabinoids, cannabinoid receptors (such as CB1 and CB2), and enzymes that help break down endocannabinoids.

When the body needs to communicate with itself, it releases endocannabinoids which then bind to cannabinoid receptors found throughout the central nervous system and peripheral nervous system.

These interactions between endocannabinoids and cannabinoid receptors work like a lock-and-key mechanism, influencing various physiological functions such as pain sensation, mood regulation, appetite, and memory.

Anti-Cancer Mechanisms of CBD

CBD has been found to impede the growth of cancer cells. It can promote cell death, prevent further growth, and stop the spread of tumors. Studies show that CBD inhibits angiogenesis, which is crucial for tumor growth and metastasis.

Additionally, inhalant CBD exhibits promise in fighting lung cancer by inducing cell death and hindering tumor progression.

Researchers believe that further exploration of cannabinoids like CBD as a potential cancer treatment is important. They see merit in investigating how CBD can be used alongside traditional anti-cancer drugs to enhance their effect on tumors.

Moreover, studies provide strong evidence supporting the concept that cannabinoids have anti-cancer properties when tested on cultured cancer cell lines. This supports the idea that CBD holds significant potential as an anti-cancer agent.

Evidence of CBD's Efficacy in Cancer Management

Research has shown that cannabinoids, including CBD, have demonstrated anti-cancer activity in lab-grown cancer cell lines. Some studies indicate that CBD may inhibit the growth of cancer cells and even induce programmed cell death in certain types of cancer.
