When I first got involved in stoner culture back in high school during my teens at the turn of the millennium, there was still a lot of the anti-marijuana propaganda still going around. At that time, there was a lot of anti-marijuana propaganda saying that weed is now more potent and dangerous than it was in the 60s and before then. The pro-marijuana side said that was all bullshit, and even went as far as saying that the potency of weed never changed with breeding. Now, looking at this more critically, I think the pro-marijuana side was trying to say that the "more dangerous" argument was all bullshit. And may've gone a little too far in saying that the increased potency was a lie as well. It sounds perfectly logical that breeders would do what they could to try and strengthen the potency of marijuana, so they could sell a better product. But is this the truth?
