Thanks to technological advancements in the breeding industry, today’s cannabis strains have a higher THC content than ever before. In the 70s, strains like Panama Red used to knock stoners’ socks off with a THC content of 15-17%. Nowadays, the strongest cannabis strains available today contain THC levels of between 30% and 34%.
Of course, we must keep in mind that different growing conditions for the same strain of cannabis might result in different THC concentrations. Most of the strains with the highest THC levels have been older phenotypes that have been crossbred and hybridized over time to have higher THC levels.
Whereas it is quite hard to identify one strain as the definite record holder, we’re presenting you with our pick of the strongest marijuana strains in 2023.
Let’s check them out!
