What Makes a Cannabis Strain "High THC"?

So, what actually makes a strain “high THC”? It’s all about the percentage of THC—the stuff in weed that gets you high. Most regular strains have around 10-15% THC, but high THC strains usually start at 20% and can even go way higher. These strains are bred to have more of the THC chemical in their buds, which means stronger effects when you smoke or vape them.

Basically, if you want weed that hits harder and gives you that intense, heady feeling, you’re looking for high THC seeds. It’s the difference between a chill buzz and a full-on, mind-blowing experience.
