For centuries (millennia, in fact), humans have cultivated cannabis and have been selecting the best plants to produce the seeds that will be used in the next harvest. Throughout this very long selection process, and in order to obtain better plants for their application in fields as diverse as medicinal, spiritual, or recreational, the trait of a high amount of THC has been fixed generation after generation, obtaining varieties with high psychoactive power.
This selection for plants rich in THC increased to a great extent from the 70s of the last century, when modern cultivation and breeding techniques focused on obtaining strains with an even higher content of this cannabinoid, being normal that today the varieties of cannabis double or even triple their THC content compared to half a century ago. But... what exactly is THC? Where is it produced and how? What are its main effects on our body? Today we answer all these questions, and many more!
