genetics

Cannabis is known to induce DNA damage by several mechanisms including damage to chromosomes at the time of cell division, dramatic reductions in histone formation which form the core of the nucleosomes around which DNA is twined and are crucially involved in signalling to the transcription and epigenetic machinery to regulate gene expression, alteration of DNA methylation and many other processes 2-6. And genotoxic stress of many types is known to trigger DNA checkpoints and interfere with the normal process of meiotic and mitotic cell division; and are also known to trigger ageing and cellular senescence pathways.
That it has been linked with all four areas, in the context of its many other known harms – respiratory, driving, impaired developmental trajectory, reduction in IQ, hippocampal shrinkage, brain disconnection and immunopathies - implies directly that the cannabis legalization debate itself is non-viable and profoundly and inherently misleading.
