The claim details a specific action by 'Acting Attorney General Todd Blanche' rescheduling the drug. While Wikipedia provides information about Todd Blanche serving as acting AG and the rescheduling event is mentioned in the context of the Trump administration, the specific details about him rescheduling it 'from a category like heroin to one for strong medicines' are not corroborated by multiple independent sources. The evidence is heavily reliant on the context provided by the search results related to the rescheduling event.

Two web search results mention a study published in JAMA Network Open regarding cannabis use and brain function. However, the claim specifies a 'major 2025 neuroimaging study' with specific findings about productivity and attentiveness. While the evidence points to recent studies in JAMA Network Open, the specific details (2025 date, exact findings on productivity/attentiveness) are not confirmed by multiple independent sources, making it difficult to corroborate the full claim.

The evidence provided for this claim consists only of web search results discussing marijuana's impact on cognitive function.

Therefore, the evidence is limited to the search results.

The evidence consists of web search results discussing the mental health risks of cannabis use. While the general topic is covered, the specific claim that marijuana 'can induce schizophrenic reactions in people with serious mental illness' is presented across multiple search snippets but lacks corroboration from a second, independent source type (like Wikipedia or another news outlet) to elevate the verdict beyond single_source.

The evidence provided for this claim is highly specific regarding increased risks of violence, killing, and suicide in younger, chronic users compared to peers with mood disorders.
