The 2026 Connoisseur’s Guide: THC vs. TAC

In 2026, sophisticated cannabis consumers look beyond the singular THC number. They prioritize the Total Active Cannabinoid (TAC) and Terpene percentage.

• TAC (Total Active Cannabinoids): This number includes THC, CBD, CBG, THCA (which converts to THC when heated), and minor cannabinoids. A flower with 38% TAC will almost always deliver a stronger, more complex experience than a flower with 30% THC but a low TAC.
• The Terpene Factor: The synergistic relationship between cannabinoids and terpenes the Entourage Effect is what gives each strain its unique power.
  • Strains high in Myrcene (like Godfather OG or Northern Lights) feel heavier and more sedative.
  • Strains high in Limonene (like Permanent Marker) feel more uplifting and euphoric.

The strongest strains of 2026 are those that master this synergy, combining record THC with rich, complex terpene profiles to deliver an unparalleled, full-spectrum high. Look for strains that boast a terpene percentage of 3% or higher for maximum impact.
