I get what you're trying to say. But the image OP displayed is actually propaganda. I get the feeling a lot of people don't know what propaganda means and think it's only something a government does to make you a gungho patriot.

If the argument, info, message, whatever form of communication being delivered to you, is designed to appeal to your emotions, or sway your opinion, even if it contains some mote of truth, it's propaganda. Smokey the Bear is propaganda. To guilt you into not starting forest fires. It's for a decent cause, but it's no less a mascot designed to alter the behaviour of the populace.

Smoking also produces a host of other chemicals, and like tobacco, plenty of harmful ones. It may not be a cannabinoid issue, rather a reaction with some combustion byproduct.

I'm not a doctor, so feel free to disregard any of that :)

What is the screaming part of it?

People have been extracting and concentrating cannanaboids for a long time. If there were more serious side effects from strong weed we'd know.

I'm sure there's some clinical documentation of all of this reefer induced disease then?

Surely your ER has to keep records and there's something... Any kind of clinical evidence that marijuana causes this?

We've spent billions and billions and billions of dollars over decades and shredded civil liberties on the so far unevidence claims of marijuana's danger, if you have actual evidence you have an obligation to come forward with it and present it for scientific review!
