How long do you hold the smoke in your lungs? Does it change depending on what sort of mechanism for smoking you use? Do you believe in the old adage, "if you don't cough, you don't get off"? Tell me about your breathing habits when smoking.
I just hold it til it gets uncomfortable, not really any method. In general, not a fan of coughing, even if it makes you higher (I don't know) I'd still rather avoid it.
I used to do this too and hold my breath for like 45 seconds per hit. I felt really stupid after reading that it's absorbed instantly, I had been doing this for years lol
