A short post about heroin voice

by Doug Muir on January 24, 2026

This was triggered by a post over at our long-term friendly-rival blog, LGM. That post, in turn, was triggered by something stupid that Robert F. Kennedy Jr. said recently.

What Kennedy said: he thinks his distinctive hoarse, raspy voice is “spasmodic dysphonia”, which he suspects may have been caused by taking flu vaccines for years.  Because dysphonia is a KNOWN side effect of these dangerous vaccines!  So he stopped getting flu shots back in 2005.

Blogger Shakezula quite correctly deconstructs this nonsense (only one flu shot lists dysphonia as a possible side effect, and that one wasn’t available until after 2005; if dysphonia is a side effect, it’s ridiculously rare, and nobody seems to have ever encountered it).  But then they make a wrong turn:  they suggest that maybe RFK’s weird voice is genetic, because his sister also has a kinda weird voice.

No.  No no no.  


There’s a thing called “heroin voice”.  And yes, it’s an actual thing — go ahead and google it.  There are papers.

TLDR: long-term heroin use can permanently damage your voice.  It doesn’t always happen, but it’s definitely a real and well-known risk.  Long-term junkies and ex-junkies often have a distinctive hoarse, raspy voice.  In rare, severe cases the user may need speech rehabilitation.  More often, they just have a weird voice.  And they may keep that weird voice for the rest of their life, because in most cases the damage seems to be irreversible.

Now on one hand this is a slightly niche topic.  If you’ve never spent much time around junkies, there’s no reason to know about heroin voice.  But on the other hand it’s not exactly a deep obscure secret.  “Raspy voice” is regularly listed as one of the warning signs of heroin abuse.  It’s right up there with pinprick pupils, pallor, reduced appetite, and a marked preference for long-sleeved shirts.

“RFK Jr. used to be a junkie” isn’t a secret either.  He’s admitted to several years of heroin addiction: basically, “It was the Eighties, man”.  I would bet a modest amount of money that he used heroin both more and longer than he’s now willing to admit, but whatever.  It’s relevant to his current position, not because he used to be an addict — there’s no shame in that — but because he grew into one of those ex-addicts who believe, that since they Triumphed Over Addiction through some combination of Clean Living and Personal Awesomeness, they’re now uniquely entitled to tell the rest of us how to behave.  If you’ve ever spent much time around twelve-step programs, you’ll know the type — mercifully rare, but instantly familiar.

Anyway!  RFK Jr. doesn’t have a weird voice because of vaccines.  And it’s not genetic either.  It’s heroin voice.   He has a weird voice because he used to be a junkie.

And that’s all.

More excellent work Doug–there’s little doubt you are dead-on about this.

Well, that was truly interesting. Thanks for clearing that up. I was going to close with a coarse bit of invective directed to Mr. Kennedy, who has much to answer for, but why?

Long-term junkies and ex-junkies often have a distinctive hoarse, raspy voice.

(The laws of physics notwithstanding, William S. Burroughs somehow intensifies.)

At least in theory, there might be another explanation: he has spasmodic dysphonia but it was not caused by vaccines. Btw, I think the radio host/personality Diane Rehm, now at the tail end of her career but still hosting a podcast, has a similar voice problem, and I’d be surprised, to say the least, if she’d ever been addicted to heroin. That said, the OP could well be right, and its explanation may be the most plausible.

Vaccines are in needles. Heroin is in needles. Therefore, vaccines bad. Also, heroin equals vaccine equals bad.

Correction/clarification: end of first sentence should read “…not caused by vaccines or heroin.”

Just FYI, all three of your links go to the same paper

Dang it.

There are, in fact, three different papers. But of course I closed the tabs.

If true, kudos to Kennedy for recovering then. Only about one in five heroin users get off the drug permanently. Of the other four, two die and two are on some form of chemical maintenance for life.

@9, those statistics seem extreme? Do you have a cite?

— That said, I definitely agree that recovering from heroin addiction is very hard. Staying clean is a real accomplishment, and one that should be respected and celebrated.

/That/ said, I will add that whatever the gross recovery rate is, it’s almost certainly a lot higher for rich guys from influential families. It’s going to be a lot easier to get clean when you have a house, no money worries, access to the very best rehab clinics and treatment, and are part of a large, politically powerful family that is anxious to avoid any hint of scandal.

One or both of these two might have been in the tabs that left us all too soon:

Shane Darke The Life of the Heroin User (2011) is a good short summary. Darke is a leading researcher in this field at the Uni of NSW.

Is “heroin voice” specific to abusing heroin in “recreational” doses, or could it also be caused by long-term therapeutic use of other opioids? Just wondering if the over-prescription of synthetic opiods in recent years (thanks, Sacklers) will cause a wider incidence of “heroin voice”.

(Incidentally, I don’t think one needs to spend a lot of time around heroin addicts to recognize the voice; tv news segments on the homelessness and opioid crises abound with short interviews of people who have this affliction).
