Marijuana is now more than twenty times more powerful than the stuff we had when I was in High school back in the 70's.

I would expect the potency to go up with time whether marijuana was legal or not. Consumers are always seeking a better product and suppliers respond. Why would I expect any difference whether the product is prohibited or not?

People have been smoking marijuana since before recorded history. Yet it is here and now that all of a sudden the potency has risen dramatically.
