The history of marijuana and how it became stronger over time goes way back. As reported by the Timber Cannabis Co, marijuana available today is on average 57% to 67% stronger than samples taken from the 1970s. This could partly be because cannabis no longer needs to be imported as much. In the 1970s, marijuana was illegally smuggled in from countries like Colombia. Along the journey, the flowers would dry out due to being compressed into cannabis bricks which made it easier to transport large amounts. Factors like light and heat reduced the potency of the plant within these marijuana bricks, meaning that what most people ended up smoking contained very little THC to actually give you a “high.”

Moreover, a lot more about how to get the best out of the marijuana flower is now known. The most potent type of plant, known as sinsemilla — which simply means the flower does not produce seeds — is the most commonly grown plant by dispensaries and has the highest levels of THC. It’s what is mostly sold today. In contrast, people in the past bought unregulated bags of marijuana that had been grown outdoors and shipped long distances and included the compressed stems, seeds, and leaves, along with the flower.
