It’s Science, people!!!
How many times have you heard:
"HOLD IT IN as long as you can!"
or
"WTF, you just exhaled—you wasted it!"

And I’m over here thinking…
Wait a minute. I'm a f***ing science genius, and something ain't adding up. So I looked into it. Turns out, when you smoke crack, the drug gets absorbed into your lungs super fast. Like, within seconds. The alveoli (those tiny air sacs in your lungs) do their job almost instantly.

You could hold that smoke in for 10 minutes, it won’t make you higher. It just makes your lungs hate you more. The “rush” isn’t about how long you hold your breath. It’s about how fast the cocaine hits your brain usually 8–10 seconds after inhaling. That’s it. Mission complete. Holding it in longer? You’re just inhaling extra carbon monoxide, tar, and toxic garbage. Congrats, you didn’t get more high, you just got more lung damage. So no, bro, I didn’t “waste it.” My lungs just aren’t trying to file a restraining order.

MYTH: Busted.
Science wins. Stay safe. Stay smart. Don’t fall for street logic.

Really though do you know if this is true for dmt too?

Yum. Ain’t that the goal?
Haha, I feel that. But yeah, really good question: Does this apply to DMT too?
Short answer: Yup. Still applies.

Longer answer:
When you smoke or vape DMT, your lungs absorb it really fast, just like with crack or cannabis. The alveoli in your lungs do their job in seconds. By the time you’re holding it in, the drug’s already on its way to your brain.

People think holding DMT in gives them a deeper trip, but that’s usually:

1. Ritual and mindset: The moment feels serious, which can affect perception.

2. Oxygen deprivation: You’re literally getting lightheaded. That adds to the “blast off” feeling but has nothing to do with more DMT absorption.

The intensity of DMT isn’t because you held your breath, it’s because it’s one of the fastest-acting psychedelics on Earth. Once it hits, you’re gone. Holding it longer just stresses your lungs. So yeah: inhale, exhale, launch. You’re getting the full ride either way. No need to marinate your lungs in cosmic barbecue smoke. Respect for asking. Solid question.

Very interesting. I've always thought that when you're smoking a singular compound (>90% purity with no cuts is what I mean), if you can still see the shit you're exhaling you're wasting it. And hell if I've ever wasted deems in this manner lmao. Cool to learn though. I'll have to try a shorter period of holding it in at some point, but the lack of breath really does flow into the trip really nicely in an indescribable way.
You said about 8-10 seconds is the maximum you should be doing?

Totally hear you, especially about that “breathless flow” into the trip. That part feels real because it is: oxygen deprivation + rapid onset can combine to amplify the experience. But from a science perspective, the DMT absorption already happened before that feeling kicks in.

Here’s the why: Your lungs are made for fast gas exchange, oxygen, CO₂, and yes, vaporized drugs. The alveoli (tiny air sacs) are lined with ultra-thin membranes and surrounded by capillaries. When you inhale something like DMT vapor, it diffuses through those membranes and into your blood within seconds, often under 5 seconds for small molecules like DMT.

Even in studies of nicotine and THC, which are heavier than DMT, 90%+ of the compound is absorbed in the first 3–6 seconds. DMT is smaller and highly lipid-soluble, so it crosses into the bloodstream and blood-brain barrier even faster. So yeah, holding it in beyond 5–8 seconds doesn't do much except deprive your brain of oxygen, which can feel like a deeper come-up but isn't tied to more drug being absorbed. Also, if you’re seeing visible vapor on the exhale, that doesn’t necessarily mean unabsorbed DMT—it could be condensed carrier material (if you're using something like changa or enhanced leaf) or just cooled vapor re-condensing. Not all visible vapor = wasted product. Try a 3–5 second hold sometime and compare the experience. You might be surprised how little difference it makes in intensity, just less lung strain and a smoother ride.

Appreciate the thoughtful convo, man,brare to see people open to dialing into the science side.

Im not trying to argue, anything like that. This is just personal experience and observation; I've been in many a room where someone was smoking meth and Crack, and got a contact high. One of those was at work, some other employee was smokin away in a stall, I walk in and boom.

do you have a link to any of those studies because I would love to read them

Yay science! It makes total sense, I remember high school biology, alveoli, basic lung function, and what you're saying is right. I was thinking about it more, and when I see someone exhale a big cloud, imo its a waste because it's enough to get a whole other person high. But there it goes. Wafting away, probably hanging out somewhere over Kansas by now.. Hopefully got some birds a nice buzz. Not to mention when I was younger, I grew up in a very small condo (1200sqf, 5 people, 3 bedrooms, 2 floors, small) so exhaling ANYTHING was not an option. I held that shit IN lol!
 
There were alot of old wives tales in this area. I've heard that breathing out half way then breathing back in gets more in your system and all sorts of other stuff. It's like the equivalent of when someone drops food on the floor and goes "seven second rule".

If you’re smoking anything with no cuts you’d be dead.

Sure buddy. Tell that to anybody who's smoked DMT. Or essentially any tryptamine. I know I'm coming across as a dick but you're just wrong & fear mongering

You aren't being a dick. Insisting on high quality and informative posts, and correcting misinformation where it comes up is why bluelight is actually useful unlike drug subreddits. Reddit is practically useless for seeking drug advice due to the amount of blatant misinformation that goes unchallenged there. Made worse by the fact that it's a system of voting to reduce or raise visibility, as if it's a common misconception or just something that "makes sense" to enough people but isn't true, attempting to correct it often gets your post downvoted and hidden by default.

I understand that the melting point of freebase cocaine to be 98°C. The range stated for DMT is ridiculous with anywhere from 38°C to 74°C. Possibly due to different polymorphs demonstrating different values.

Now I have no idea if only the vapour or the vapour and the aerosol are absorbed.

I feel I have added data that doen't answer the initial point. But I hope it's of at least some value to others
 
Good luck telling a crack head to not hold in his crack hits. They can blow through a $50 rock in less than 20 mins and will call up the plug again no matter how many times they told themselves they needed food or Christmas presents for the kids. Same with dope.

Downtown Newport News, VA has some strong ass crack. They still have real heroin there as well. But it is now $160 a bundle due to demand over fentanyl.

What I found what with weed or crack exhaling out the nose gave a better effect. Also washing the crack before smoking makes it much better.
 
I’m not being a dick , mostly because I don’t know everything and also because I have more than 25 years of experience with heroin/fentanyl, methadone/suboxone, coke/crack, over 30 inpatient treatment centers…etc., etc.,

Experience cannot be bought or taught…but kindness and compassion can be passed on from me to you…
 
@Stassi202 - I am out-of-the loop but long, long ago a friend asked me to slip a sample into a set of compounds we were sending off for instumental analysis. I was assured that the compound was not legally controlled (either explicitly or implicity). It turned out (based on NMR and GC-MS data) to be essentally pure phenacetin which was a paracetamol (acetaminophen) prodrug that had been taken off the market decades before due to toxicity. I had NO idea why on earth someone would wish to know.

Turns out people were selling it as 'Turbo Mix' or 'Super Mix' and although I have no idea what the official usage was stated to be, but I was then told that it was a cut used to bulk out crack cocaine.

Sorry if this is old news but I figure it's better to tell someone twice than to assume they know and as a result suffer avoidable harm. I seem to recall reading the physical data on phenacetin and it sort of made sense. But how on earth it was mixed in, I really have no idea.

The SAD State of the USA huh.
If you said this where I live in The UK you would be laughed out of town.

correct, the US struggles when it comes to illicit drugs

also the campaign against "pain patients & benz patients" to remove them from their medications due to the community of addicts that have never had a legit legal pain or benzo Rx from a doctor. right now the US is at it's lowest prescribing of pain medications since 1992 and suicide rates are up 900% from pain patients being forcefully removed from their stable pain medications.

I would say that is a sad state of affairs in every sense of the definition.
