We want to cut through the noise. Whether you’re canna-curious or looking to make your first dispensary visit, we’ll walk you through everything you need to know—from how it makes you feel to how it’s used, what types exist, and how to shop smart.
What Is Cannabis?
Cannabis is a plant that has been used for centuries for its wellness, healing, and psychoactive properties. It contains naturally occurring compounds like THC and CBD, which interact with the body’s endocannabinoid system to produce effects such as relaxation, pain relief, or increased appetite.
There’s much more to the plant’s story—from how it’s cultivated to how it works and is regulated.

What’s the Difference Between THC and CBD?
Two of the most well-known compounds in cannabis are THC and CBD. Understanding the difference between them is key to knowing how cannabis might affect you.
- THC (tetrahydrocannabinol) is the main intoxicating compound. It’s what produces the feeling of being “high.”
- CBD (cannabidiol) is non-intoxicating but may still influence mood, relaxation, and other wellness effects.
The ratio of THC to CBD in a product can significantly impact how it makes you feel.

Sativa, Indica, and Hybrid: What Do These Mean?
Cannabis is often categorized into three general types based on its effects and plant structure:
- Indica strains are commonly associated with body relaxation and evening use.
- Sativa strains are linked to uplifting, energizing effects and daytime use.
- Hybrids are crossbred to offer a balance of both.
These categories can be helpful but aren’t always consistent—effects also depend on cannabinoid and terpene content.

How to Shop Smart for Cannabis
Shopping for cannabis can feel overwhelming at first, but a few simple tips can help you make informed choices:
Know your goals. Are you seeking relief from a specific condition or looking for help with relaxation or sleep? Let your desired outcome guide your product choice.
Read product labels. Look for the THC and CBD content, dosage form, and terpene profile if available.
Ask questions. Don’t hesitate to speak with a dispensary pharmacist or wellness associate—they can suggest products based on your tolerance, preferences, and goals.
Avoid buying based on strain names alone. Strain names like “Blue Dream” or “OG Kush” aren’t standardized—look at the actual cannabinoid and terpene content instead.
Start with low-dose formats. Especially if you’re new, choose tinctures, troches, or vaporized products that allow you to ease into your experience.
