I don’t know what I read, but someone said weed before all of the legalization in the last ten years was 5% THC. The stuff being sold in dispensaries now is 80-95% THC. Weed went commercial and so did the potency. Corporate America got a hold of the industry for pure profits.
You can purchase concentrates which are oils or resins at high THC percentages. These are manufactured from plant material to concentrate it not unlike making orange juice concentrate.
The theoretical physical limit of THC development in the plant is around 30%. You cannot find flower that will test much higher than that - if that.
Yes it’s more potent than it was due to - drumroll - modern agricultural practices.
This kind of misinformation parroting is really no bueno.
