The world of cannabis is constantly evolving, with breeders pushing the envelope in terms of potency, aroma, flavor, and medicinal benefits.

Here’s a definitive guide to the Top 5 Strongest Cannabis Strains of 2023.

Understanding Cannabis Strains

Before we delve into the top strains, let’s quickly skim through the basics of cannabis strains. You’ve probably heard the terms “Indica,” “Sativa,” and “Hybrid,” but what do they mean?

Indica strains are known for their relaxing effects, often used for night-time use or to relieve stress. Sativa strains have a more uplifting effect, promoting creativity and social interactions, perfect for daytime use. Hybrids, as the name suggests, combine the effects of both.

How Is Cannabis Strength Measured?

Strength in cannabis is generally measured by its THC content, the psychoactive component that gives the “high.” However, strength can also refer to the richness of other cannabinoids and terpenes, which can deliver varying effects and medicinal benefits.
