Are people so dense that they don't understand this flier to be a good thing?
Yes. But that's what happens when morons blindly subscribe to the "DRUGS ARE ALWAYS BAD" dogma, rather than rationally looking at the facts and attempting to educate and reduce harm. Or the arbitrary definition of legal and illegal drugs.

Whilst I don't take drugs myself, I have no respect for the various laws that exist around the globe, whether that's in the UK where I live, or elsewhere. They sell complete bullshit instead of honest facts, and people see this.
