Marihuana: much ado about THC

Abstract

The availability of delta 1-THC, the major psychoactive component of marihuana, in pure form offered an opportunity for better understanding of the mechanism of action of this drug. Two decades after the isolation of delta 1-THC its mode of action is still obscure despite the enormous amount of research invested in it. Studying cannabis content as a whole offers a different approach for better understanding of this ancient weed and its effects.
