There's so much more going on in this story, thematically and in the subtext, the "anti-drug message" is almost just a set piece to allow them to develop. Right off the bat "Fred" slips from his written speech and mumbles about how this crap (the anti-drug propaganda) is the reason why people do drugs in the first place and that if they want to stop the problem they need to eliminate the demand, not just the supply. The entire plot is a big tangled loop. Fred is investigated Arctor (himself, even before he can't tell the difference), trying to get up the chain of supply through Donna, at the request of Hank, who IS Donna. All ultimately to get Arctor so burned out on the drug that he gets into New Path, who are the "rehab" organization with a government contract, that make the drug itself. The cops can't bust New Path because the government won't let them scan their farms. The snake is eating it's own tale, metaphorically. There's a lot of commentary there about why people do harmful drugs, why they abuse them and what incentive authority figures have to keep busting the users and sellers, without going after the sources of the problems on both ends.
I'm sure P.K. Dick had a lot of strong opinions about hard drugs and wanted to convey a certain amount of dissuasion from them. He certainly did a lot of those and felt the negative effects in the most severe ways. The way he delivered that message though was simply to show how self destructive drug addicts behave. He doesn't even demonize it, as Arctor discusses early in the film why he allowed it all to happen. How sometimes things were *beep* and sometimes they were beautiful, but essentially at least he never knew what to expect, instead of being bored with his life. The story isn't asking the viewer to either embrace the lifestyle of Arctor or demonize him or the drug, it's a pretty objective view. Some of his misery is of his own doing, some of it is thrust upon him. Some good may come out of this pain and plenty of pain came from his prosperity. That's a pretty non-controversial overview of real life with or without drugs. It goes back to the whole "eliminate the demand" sentiment. Bruce/Bob/Fred is as much a victim of his own desires and flaws as he is the patsy of the bigger plan, which seems to be ultimately the system fighting itself even as it becomes the enemy it's trying to take down. It's almost impossible to distinguish the heroes from the villains here. They pushed him along the path, he allowed (and even somewhat wanted) it to happen.
All besides the fact that they're not really talking about smoking a joint or getting drunk or taking a pill at a dance party or something. The kind of drug use being portrayed in the story is serious addiction, not recreation. If you're not taking a critical view of the story and exploring it's themes beyond a cursory overview of the basic plot, you're going to be subject to your own insecurities and reactionary tendencies with it. The film isn't telling you "you're a piece of *beep* for doing drugs, see?!", but you can certainly make yourself feel that way about it if you're appropriately inclined/impaired.
A few here have hit on the bigger picture, but most have missed it, and I'd like to give my take on it.
From the moment Arctor privately states that the propaganda is actually fueling the problem, we are given a strong hint at what the underlying message is. Subsequent dialogue throughout the movie confirm this, and the message is: The drug war and prohibitionist mindset, are not only fueling the problem, but that corrupt corporations and government agencies are prone to getting involved in the business.
The film is a conspiracy tale, first and foremost. Everything else are legitimate sub-plots and aspects, but they are not the 'big one'.
There are many researchers and journalists who have documented the illegal promotion of the drug war by various governments and corporations, through production, trafficking and sales.
Those who think this is a 'dopehead' film, or an 'anti-drug' film, have completely missed the boat.
I think that even if the anti-drug message was unappreciated, there was a whole lot else to take away from it - the paranoia and dehumanization by chemical was really quite fascinating, and the ending reveal was pretty freaking crazy.
Also the anti-drug message wasn't handled in a way like other movies do. Contrast this movie with Avatar, a movie that I like, but beats you senseless over the head with its message. A Scanner Darkly didn't just come out and say "hey man, drugs... they're bad," it instead showed how people would be reduced to animals on both sides of the equation - New Path uses a rehabilitation front to cover its facilitating of the very drug it 'fights against,' while those who fight against New Path must break a person down in order to confirm this.
What the audience will glean from this in the end is that Drugs are bad, but we get to step back and look at it in a worst-case scenario, even though many of the more important elements of the drug world are similar/the same between real and fictional worlds. It's good stuff
I don't know that the movie was preachy anti-drug garbage.
But I do know that, as I've gotten older, I have had to stop associating with addicts and recreational drug users because, to a person, they were unreliable, infantile and annoying.
The least reliable and most annoying of the sort? Pot smokers.
"The least reliable and most annoying of the sort? Pot smokers. "
LOL, basically, the only drug users/abusers you've been around were pot smokers. People whom you label as both "least reliable" and "annoying."
I'm going to leave cocaine out of this because cokeheads are in a class all their own.
But you've obviously never been around people who do drugs that cause physical addiction. Believe me, if you think potheads are annoying, wait until you get the scourge of an opiate addict -- or worse, a methamphetamine addict -- in your life. Then come back and give us an updated report on the annoyances and unreliability of pot smokers.
There's way too much judgment in your subtext and as such you happen to be the type of person PKD is writing about; someone who thinks they're better than the "dirty" person who does drugs;someone who perceives the drug culture as this separate reality.
Why do people turn to drugs; more importantly, why do people turn BACK to drugs?
More often than not it's because the people around them don't understand what they're going through and view them as a lesser human being because of it.
I've seen VERY good and intelligent people flush their lives due to drug abuse. Likewise, I've seen people who are such huge screw ups due in part because of their drug use able to continue their lifestyle with few repurcussions privately, publicly or legally.
Most, however, are normal people. If you didn't know they did X, Y or Z you would never suspect it. Most have families. Most have quite a keen awareness of moderation. You're no better than anyone else, be they drug dealers, prostitutes, homeless or addicts. You may have been conditioned to think that, but the reality is the same genes are found in their cells; you're the same on the inside. Pretending otherwise is a little pretentious.
