Digital addictions operate via dopamine and engage largely the same brain regions as substance addictions such as heroin or crack cocaine, producing compulsive use and withdrawal symptoms.
"It's all of this is working through dopamine. If you feel compulsive use, definitely dopamine. So, it's most of the same brain centers as it is for heroin or crack or any other drug. Um and it's the same effects. That is, the it's it's compulsive use where you don't want to do what you want to change, but yet you find yourself doing it, and you have withdrawal effects."

Neuroimaging and neurochemical research on digital addictions (most extensively studied in internet gaming disorder) demonstrates substantial neurobiological overlap with substance use disorders, including alterations in dopamine-mediated striatal reward pathways, cue-induced cravings, and reduced prefrontal cognitive control. However, equating digital screen use directly to severe chemical substance addictions such as crack cocaine or heroin overstates the equivalence. Reviews emphasize that digital behaviors also activate broad sensory, motor, and cognitive networks not specific to substance dependence, physiological dopamine surges differ substantially from direct pharmacological agents, and evidence for neurobiological withdrawal mechanisms in behavioral addictions remains limited compared to substance use disorders.

"Videogame playing may be supported by similar neural mechanisms underlying drug abuse. Similar to drug and alcohol abuse, internet addiction results in sub-sensitivity of dopamine reward mechanisms. Given the fact that this research is in its early stage it is premature to conclude that internet addiction is equivalent to substance addictions." (abstract, conclusions, passage verified)

"Brain imaging studies have shown that IGD shares, to a large extent, neurobiological alterations that are typical for other addictions, such as: (i) activation in brain regions associated with reward, as evident from cue exposure and craving studies and neurotransmitter systems studies that indicate an involvement of dopamine-mediated reward mechanisms; (ii) reduced activity in impulse control areas and impaired decision making; and (iii) reduced functional connectivity in brain networks that are involved in cognitive control, executive function, motivation, and reward."

AI companion chatbots have driven hundreds of thousands or millions of individuals into psychosis.
"They already have driven hundreds of thousands or millions of people into psychosis." (said at 1:38:35)
While published psychiatric literature and case reports document that interactions with conversational AI chatbots can validate, amplify, or precipitate delusional ideation and psychotic symptoms in vulnerable individuals (often described via mechanisms such as sycophancy, confabulation, or delusional feedback loops), there is no epidemiological evidence indicating that hundreds of thousands or millions of individuals have experienced chatbot-induced psychosis. Documented evidence to date is restricted to isolated case reports, small case series (such as syntheses examining around 35 reported instances), and scoping reviews of media narratives.

"A total of 71 news articles representing 36 unique cases were included... While causality cannot be established from media reports, consistent patterns of high-intensity interactions, user vulnerability, and limited safeguard reporting highlight the need for structured safety surveillance, transparent AI risk auditing, and clearer governance frameworks."

"We conducted a targeted literature review and case-based analysis of 35 reported instances in which interactions with generative AI systems were temporally associated with the onset or worsening of psychotic symptoms. Across cases, recurrent patterns included reinforcement of delusional beliefs, amplification of pre-existing psychiatric vulnerabilities, promotion of harmful behaviors, and dissemination of unsafe medical guidance."

"Articles on AI psychosis propose several potential links between delusional beliefs and LLM-based chatbot use, such as risks of chatbots reinforcing and validating delusional beliefs. This structured, integrative overview shows that theoretical and empirical work identify various hypothetical and observed harms associated with the use of LLM chatbots in mental health."
