HULKBERRY

I smoke it like a regular cigarette. Absorption into the blood, lung capacity, and concentration - THC. All three parameters are important. The thing is, even though the concentration in the smoke is high, the alveoli in the lungs absorb as much as they can take. If they could take in unlimited amounts and release carbon dioxide, say, through the rear end, then yes, breath-holding would have a huge effect, and we could swim underwater longer, fully loading our lungs. But the alveoli also need to give back carbon dioxide. So it turns out that you inhaled stuff with 25% THC, but in reality, only about 5% of what you inhaled made it into your blood, because more than that just isn't possible. Accordingly, your wife also inhales the leftovers, but with the carbon dioxide you exhaled and a little bit of oxygen left. That's where the trick lies. The lungs start absorbing everything except carbon dioxide, so she gets not oxygen, but the leftover THC, which is why after your kiss she gets a bigger dose than you do. That's why my wife and I never kiss, but smoke the same joint, so the high is the same.
