Adding ammonia compounds like diammonium phosphate converts nicotine to freebase form, allowing it to cross the blood-brain barrier faster than natural nicotine salts.
"They added ammonia compounds, specifically diammonium phosphate, to convert nicotine into its freebased form... Freebased nicotine crosses the blood-brain barrier much more rapidly than nicotine salts that occur in wild tobacco." (said at 0:03:24)
Ammonium compounds added to tobacco do increase smoke alkalinity and convert nicotine salts toward the unprotonated freebase form, which increases volatile nicotine yield in smoke. However, evidence shows that nicotine absorption across physiological interfaces occurs rapidly regardless of the initial acid-base state of the inhaled particles because the lung-blood interface rapidly buffers nicotine. Observed changes in nicotine blood kinetics following smoke ammoniation are predominantly driven by higher nicotine delivery in the smoke rather than a faster intrinsic rate of absorption or biological membrane transport for freebase nicotine.

"The observed change in the kinetics of nicotine (i.e., shorter t(1/2) and higher c(max)) after ammoniation is, however, predominantly due to the higher concentration of nicotine in the smoke, rather than to an increase in the absorption rate of free-base nicotine in the respiratory tract."

"When particles deposit on the lung-blood interfaces, nicotine is absorbed rapidly, regardless of the acid-base nature of the particles. This is due to the buffering capacity of the lung-blood interfaces and the small mass of nicotine per puff distributed over a large number of particles depositing onto a huge lung surface."

Every dose of nicotine raises heart rate by 10 to 15 beats per minute and blood pressure by 5 to 10 mmHg.
"Every dose raises your heart rate 10 to 15 beats a minute and every dose raises your blood pressure 5 to 10 millimeters of mercury." (said at 0:19:35)
Acute nicotine administration stimulates the sympathetic nervous system and temporarily elevates heart rate and blood pressure. However, stating that 'every dose' produces a 10 to 15 beat per minute increase in heart rate and a 5 to 10 mmHg increase in blood pressure overstates both the magnitude and consistency of the response. First, acute tolerance (tachyphylaxis) develops rapidly with repeated dosing, attenuating subsequent cardiovascular responses. Second, controlled clinical trials and meta-analyses show average acute increases that are often more modest (typically ~3 to 6 bpm in heart rate and ~3 to 6 mmHg in blood pressure).

Nicotine pouch use among youth quadrupled between 2022 and 2025, and lifetime use among 12th graders rose from 7% to 10% in a single year.
"Nicotine pouch use among the youth has quadrupled between 2022 and 2025. Lifetime use among 12th graders went from 7% to 10% in a single year." (said at 0:21:48)
The speaker overstates the scale and rate of increase in youth nicotine pouch use. Data from the Monitoring the Future study (a nationally representative survey of US 10th and 12th graders) published in 2025 showed that lifetime nicotine pouch use among 10th and 12th graders increased from 3.0% in 2023 to 5.4% in 2024 (an 80% relative increase, or roughly 1.8-fold), and past-30-day use increased from 1.3% to 2.6% (a doubling). Multi-country survey data of youth aged 16–19 (in Canada, England, the US, and New Zealand) similarly showed no significant change in lifetime use between 2022 and 2023, followed by a modest increase in 2024 to around 5% lifetime use in the US. Lifetime use among 12th graders reached 5.4% across 10th/12th graders in 2024, nowhere near 10% lifetime use in a single year, nor did overall youth pouch use quadruplicate.
