These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Anvilicious: Usually averted except in the case of governmental exploitation and drug rehab centres, which tend to be a rather painful subject. Also he seems to have a few issues with abortions, as the short story concerning "Pre-persons" makes fairly clear.

Dick wrote a book in 1963 with a working title of A Terran Odyssey. It was eventually published with the name Dr. Bloodmoney, or: How We Got Along After the Bomb, as a reference to the Stanley Kubrick movie Dr. Strangelove. Kubrick's next project, three years after the release of Dr. Bloodmoney, would be 2001: A SPACE Odyssey.
Narm: For all Dick's strengths as a storyteller, his actual prose rarely rose above workmanlike (as he was pumping out sixty pages a day while flying high on amphetamines just to scrape a meager living together), and on occasion it plummeted straight down into the realm of god-awful so hard it became ridiculous.
Fictional drugs play significant roles in several other stories, such as Can-D (which tranfers your mind into a Barbie-like doll named Perky Pat) and Chew-Z (an afterlife-simulating hallucinogen that allows the title character to control your perception) from The Three Stigmata of Palmer Eldritch.
