The state of Texas allocated $50 million in funding for ibogaine research.

"and I think in Texas there's $50 million allocated for research effort on ibogaine, which is like—I was sort of shocked to see." (said at 0:17:34)

While legislation has been introduced in the Texas Legislature to establish a consortium to sponsor and conduct clinical trials for ibogaine to pursue FDA approval for opioid use disorder and related conditions, the state of Texas has not enacted an approved $50 million appropriation for ibogaine research. High-profile proposals exploring significant public funding for ibogaine research (such as a proposed $42 million allocation from opioid settlement funds in Kentucky and legislative consortium proposals in Texas) have been actively debated, but treating a $50 million state allocation as enacted funding overstates the status of state legislation.

In a study of veterans undergoing ibogaine treatment, participants exhibited a sustained reduction in alcohol consumption that approached zero despite not seeking treatment for alcohol use.

"So, our data, we we also collected alcohol use. Um, and what we found was, and we're going to publish this soon, that uh people's alcohol use really precipitously dropped almost close to to zero. And so just almost everybody just really dramatic improvements in alcohol um and uh and maintained it." (said at 0:40:39)

While prospective observational data on Special Operations Forces Veterans receiving combined ibogaine and 5-MeO-DMT treatment showed a statistically significant reduction in alcohol misuse scores through 6 months post-treatment, the claim overstates the magnitude of effect and proportion of participants who benefited. Rather than alcohol use dropping 'almost close to zero' for 'almost everybody', only 24% of veterans with baseline risky drinking achieved total abstinence at 1 month (16% at 6 months), and 53% remained risky drinkers at 6 months. Additionally, these open-label observational findings lack a control group.

"There was a significant reduction in alcohol use from pre-treatment (M = 7.2, SD = 2.3) to 1 m (M = 3.6; SD = 3.5) post-treatment, which remained reduced through 6 m (M = 4.0; SD = 2.9; p < .001, partial eta squared = .617). At 1 m, 24% were abstinent, 33% were non-risky drinking, and 42% were risky drinkers. At 6 m, 16% were abstinent, 31% were non-risky drinking, and 53% were risky drinkers."

Survivors of the October 7th festival attack in Israel who were under the influence of MDMA exhibited a statistically significantly lower incidence of PTSD onset compared to those who were not.

"There's an analysis of the, you know, events that happened in Israel with the with the rave, right? And in that situation, there was a certain percentage of those people that were actually on MDMA. I don't know if you know about that. ... They actually saw a statistically significantly lower PTSD onset in individuals that were on MDMA compared to people that weren't for that experience" (said at 0:54:15)

Studies examining survivors of the October 7, 2023 Nova festival attack who were under the influence of psychoactive substances (including MDMA/empathogens and classic psychedelics) have explored peritraumatic experiences and psychological outcomes. Preliminary mixed-methods and observational survey data suggest that survivors frequently reported subjective benefits in acute emotional coping and functionality during the attack, alongside complex post-event integration. However, claiming a definitive or established protective effect against PTSD onset overstates the evidence, which consists of retrospective, uncontrolled observational and qualitative data subject to substantial recall bias, self-selection, and confounding.

Food- and diet-related chronic disease kills over one million people annually in the United States.

"chronic disease related to food is, you know, killing a million-plus people a year in America." (said at 0:42:35)

While chronic conditions such as cardiovascular disease, cancer, and type 2 diabetes collectively account for over 1.5 million deaths annually in the United States, epidemiologic modeling indicates that suboptimal diet is attributable to roughly 300,000 to 500,000 deaths per year—not more than one million. In a nationwide comparative risk assessment published in JAMA, suboptimal intake of 10 dietary factors was associated with an estimated 318,656 cardiometabolic deaths (45.4% of total deaths from heart disease, stroke, and type 2 diabetes) per year in US adults.

In the 1700s, many European physicians rejected citrus fruit as a treatment for scurvy, and members of the British Royal Society argued that limes and lemons might make scurvy worse.

"Many of them thought these were-- you know, there weren't that many limes and lemons in Europe at the time, right? This this was considered a South American or an African exotic plant. And so most of the physicians of the day actually rejected uh citrus fruit as a treatment for scurvy. And so as you know the story of anti-fruiters, right? There were lots of people in the British uh Royal Society that said that the that the limes and lemons may actually be making scurvy worse." (said at 1:03:40)

Historical medical literature confirms that in the 18th century, academic physicians and institutions like the British Royal Society largely ignored, dismissed, or delayed adoption of James Lind's 1747 trial demonstrating the efficacy of citrus fruit. Key figures, such as Royal Society president Sir John Pringle, heavily promoted competing theoretical treatments (including malt wort, elixir of vitriol, and purgatives) based on prevailing theories of putrefaction and humoral imbalance. However, claiming that European physicians viewed citrus as an exotic South American/African plant (citrus had been cultivated in Mediterranean Europe for centuries) or that Royal Society members formally argued citrus made scurvy worse overstates and embellishes the nature of 18th-century medical resistance, which was characterized by adherence to alternative theoretical frameworks rather than a claim that citrus actively aggravated the disease.

"In the last five centuries sailors and some ships' doctors used oranges and lemons to cure and prevent scurvy, yet university-trained European physicians with no experience of either the disease or its cure by citrus fruits persisted in reviews of the extensive but conflicting literature."

Despite clear evidence, Lind’s recommendations were largely ignored during his lifetime because of prevailing theories and theorists — while pretentious and misguided scientific debate raged on in the Royal Society, scurvy was killing tens of thousands of mariners" (abstract, passage verified)
