My home has four thousand dollars of hospital-grade air filtration equipment due to indoors vapers in this complex that do so at least once daily where the entire complex smells it. There is a way to purge what is left of it by using magnesium sulfate soaks; that is powerful enough to remove lead and mercury poisoning; it is more than powerful enough to remove toxins I inhale over the course of a week in under fifteen minutes per soak.
That's how I recover so fast and fully even with a chronic asthma attack in this area. My primary physician did a test study on my lungs recently; zero damage whatsoever, and my lungs/oxygen capacity has actually far more than doubled in the past month.
That's what I get for being a medical physicist by trade and doing my own research, contributions, and applications of tested (a theory is, by definition, tested and repeatable; that term is often misunderstood) medical science with international medical database records that are far more extensive than NCBI/Pubmed:

Don't listen to the youtube bandwagon's garbage "medical advice". And don't let any fear try to trick you into thinking any kind of toxin, poison, etc. _has_ to be permanent; I lived through septic shock and am healthier than ever before; my survival prognosis was zero percent around four months ago, yet here I am and the disease I had (caused by bacterial pnemonia entering my bloodstream) is long dead.
Due to a failure of a contracted employer, I had a break in medical coverage at that point in time; I could only afford the initial check-in and zero treatments, yet I am alive.
Even my body was having the convulsions that typically occur just before death, but that was many months ago, and I saw a physician last month who confirmed that I fully recovered from it and was in shock, even when I gave her my background information on how our intense training enables us to thrive in situations people would think are impossible.
