Cannabis use among youth (12-18 years old) is strongly linked to an increased risk of developing schizophrenia or psychotic episodes later in life, even after cessation of use.

This warning is based on robust scientific literature identifying adolescent brain development as a period of particular vulnerability. Large-scale observational studies, including analyses published in 'The Lancet Psychiatry' and 'JAMA Psychiatry', support the existence of a dose-dependent association between early use of high-THC cannabis and the incidence of psychotic disorders. It is important to note that this research highlights a strong correlation, although direct causality is complex to isolate due to pre-existing genetic and environmental factors. The argument that cannabis is 'harmless' is largely contradicted by this data, particularly for developing brains. What is sometimes nuanced in the research is the distinction between occasional and intensive use, although the risk remains a major public health concern. In summary, Huberman's observation accurately reflects the current consensus on the neurodevelopmental risks of cannabis in minors.
