THCA Diamonds 💎 1GTHCA diamonds are one of the newest innovations in the cannabis industry, and they’re getting a lot of attention from consumers. They’re the current leader to present the strongest concentrate possible. This ultra-processed form of cannabis is refined until it hits levels of over 99% pure THCA. THCA has no psychoactive effect if a consumer eats it, and turns into nearly straight THC upon being smoked or dabbed. When it comes to raw power, diamond concentrates are much more effective than even wax, shatter, and live resin.
