C0nc0rdance recently posted a video about the negative effects of marijuana. I'm as square as he is, but I did have a general leaning towards legalization, mostly due to the negative effects prohibition had on society, but partially due to some misconceptions I had about marijuana being relatively safe. I wonder if he might do later videos about tobacco and alcohol so that he can give us some comparison. Either way, I'm currently moving back towards neutral on the issue of marijuana legalization, based on what I know at this particular moment.
Of course, one of the stupid 'positive' myths uses the stereotypical altie argument that marijuana is herbal, therefore it's okay. Tobacco's pretty much herbal, and you don't see many people saying it's safe because of that. Or at least I don't, aside from one troll who stopped by Orac's a while back.

Let us imagine we have encountered someone who denies the accuracy of quantum mechanics. Any informed layman should know that QM plays an extremely vital role in our current civilization. Transistors, for example, are ubiquitous in our computer-driven infrastructure. If QM wasn't reasonably accurate, you wouldn't be able to read this blog post.
Given my experience with other forms of denialism, there are a number of standard arguments presented at this point:
First comes the argument that all the experts are in on some kind of sinister plot, knowingly lying about QM to students, and only allow the top students to be in on the "real" theory that actually drives our technology.
How would this conspiracy maintain itself? If they distributed information that they know is false, how would they maintain the illusion of its accuracy? How would they prevent any curious person from experimenting and finding the "real" answer? How could they silence him? And how would they pay for all this beating around the bush? WHY would they set up such a conspiracy? What would they have to gain?
Next, there's the idea that mankind just stumbled on the technology without any understanding of the underlying mechanics. While there are some examples of such luck, it wouldn't last long. The false theory would stumble on more and more wrong predictions as time went on, and solving an unexplained anomaly is how scientists gain prestige. You don't get research grants for maintaining the status quo.
And finally, one of the most common responses is to remain ignorant of the theory's successful predictions, no matter how many times they are asked to account for it.
This story is the same for just about any major scientific theory. Evolution was how we breed animals and plants according to our desires. Evolution also gives us an understanding of medicine. Heliocentrism and gravitation give us the ability to send probes into deep space. Relativity gives us the Global Positioning System. If science didn't produce reliable results, we wouldn't have these things.
Science. It works, bitches.
