Understanding THC Percentages: What NY Shoppers Should Know

If you’re exploring the New York legal market, you’ve probably seen product labels showing THC percentages — but what do they actually mean?

At Green Leaf NY, we meet many first-time and returning shoppers who are unsure how to read or compare these numbers. If you’re asking questions like “Is 20% THC strong?” or “Do edibles have a percentage too?”, you’re not alone.

Let’s break down how THC percentages in NY work, what they mean for your experience, and how to shop smarter.


What Does THC Percentage Measure?

THC (tetrahydrocannabinol) is the compound that causes psychoactive effects. The percentage listed on a product label shows how much THC is present by weight:

  • For flower: The label might say 18% THC, meaning 180mg of THC per gram.
  • For concentrates and vapes: Percentages are often higher (60–90%+).
  • For edibles: You’ll typically see milligrams (mg) per serving, not percentages.

🧠 Important: Higher percentage doesn’t always mean “better.” Your experience depends on tolerance, terpenes, dose, and format.


What’s Considered “High” or “Low” THC?

Here’s a general guide for flower:

  • Low THC: Below 15%
  • Moderate: 15–20%
  • High THC: 20–30%
  • Very High: 30%+ (rare and often from premium indoor strains)

Keep in mind: a strain with 17% THC but high myrcene or limonene can still hit strongly. Terpenes play a big role in the experience — not just the number on the label.


How to Choose the Right Range for You

Not sure where to start? Here’s a quick guide:

  • 🟢 Beginners: Start with lower THC (under 18%) or balanced products with CBD
  • 🟡 Occasional users: 18–24% may feel uplifting or relaxing without going overboard
  • 🔴 Experienced shoppers: Over 25% may offer a heavier effect — proceed mindfully

Also consider intake method. For example, a 5mg edible can feel stronger and last longer than a few puffs of a 20% pre-roll.


THC on NY Labels: What to Look For

New York–licensed cannabis products must include detailed test results. For flower, you’ll often see:

  • THCa and Total THC
  • CBD and other cannabinoids
  • Terpenes (sometimes listed by percentage)
  • Packaging and lab testing info

This ensures you’re getting a product that’s tested, traceable, and compliant.
