I think he manages to cast them in a funny light
5 Pro-Marijuana Arguments That Aren't Helping
#5. Taxing it Will Save the Economy
#4. We Need it for Cancer Patients! And to Make Paper
#3. It's Good for You
#2. Alcohol and Tobacco are Worse, and They're Legal
#1. It's not Addictive
of course what makes it funny is that he's saying the arguments are not working 'on the people we need to convince, the old stuffy politicians who are in power, and don't smoke.
EDIT: as long as we buy into the view of the world as drug users being bad guys who should be separated from society, we'll be vulnerable to these types of slurs (meaning what he wrote, not the specific list). What he fails to see in his TV view of the world, is that more relevant than whether the drug is changing the user, is why the user reached for it in the first place? if only 17% of people who try Meth get hooked, then only a small percentage of the population has a pre-tendency to want/need/high-likelyhood of abuse/whatever...and if as Dr. Gabor Mate says all of these people have developmental issues, then again, is prison where we want to send Aunt Jane? or the kid down the street who's coming back when they get out? End the war on drugs. it's a failure because it goes after the wrong people, and doesn't allow any dialog for mental health of the society at large because the real issues are eclipsed by the media hype and tradition.
