Just to play devil's advocate for a minute (even though Scooter is pushing total bullshit, as always) let's suppose that contemporary weed is s00peR d00p3R POTENT compared to 1980's weed.
So fucking what? It's WEED, not China White. FFS.
In the final analysis, it doesn't matter. What matters is that RWHN is on the wrong side of history, and I'm going to enjoy watching his efforts fail.
Oh, I know it is coming. And you will find it is not the bill of goods you've been sold by the legalization people. They could give a fuck about your personal freedom, they are after one thing and one thing only, Green. And so we'll have another legalized vice, alcohol and tobacco will be just as strong as ever, and you'll have more addiction, which will require more treatment, it will require MORE enforcement to keep it from kids (which will ultimately never be enough).
Add all of those "mores" up and you have something that is going to cost, not save, and all of the money is going to go to the industry, because they will fight tooth and nail all of these taxes they supposedly support,
You are being completely fooled but you are too stupid and blind to recognize it.
Way to go America!
