The Basics of THC and CBD – What You Need to Know

THC and CBD are the two most well-known cannabinoids in cannabis. They’re often talked about together, but they have very different effects. Here’s what you need to know to get started.

What is CBD?

CBD (cannabidiol) is non-intoxicating. It doesn’t make you feel high, which is part of why it’s popular in wellness products. You’ll find it in oils, capsules, gummies, creams,almost everything.

What it can do:

• Help you feel calm
• Support pain or inflammation relief
• Improve sleep (if taken at night)
• Help you stay focused (when taken in the morning)

Its effects are subtle, so you might need to try it a few times to notice how your body reacts.

What is THC?

THC (tetrahydrocannabinol) is the compound that makes you feel high. It interacts with receptors in your brain and body, mimicking natural chemicals your body already makes,but with a stronger punch.

What it can do:

• Shift your perception of time and senses
• Make you feel euphoric or relaxed
• Stimulate your creativity
• Increase appetite
• Help with stress or pain

Possible downsides:

• Anxiety or paranoia
• Short-term memory issues
• Nausea (especially in high doses)

Everyone reacts differently depending on tolerance, dose, and body chemistry.

Cannabinoids 101

Cannabinoids come in two types:

• Phytocannabinoids , made by the cannabis plant
• Endocannabinoids , made naturally by your body

THC and CBD are just two of over 100 cannabinoids found in cannabis. Others include:

• CBN – formed when THC breaks down, may help with sleep
• CBG – thought to have mood and gut health benefits
• CBC – under research for anti-inflammatory and brain effects

Each cannabinoid has its own profile and interacts with your body in different ways.

Final Take

CBD and THC are the main players in cannabis, but they’re only part of the picture. They work with your body’s endocannabinoid system, and how they affect you can depend on when, how, and why you use them.
