As is known cannabis causes a dramatic increase in genetic junk by chromothripsis and other mechanisms.
And is known to be linked with deformed chromosomes…
Including small circular chromosomes.
Such small circular DNA fragments have long been known to be detectable in the serum of cancer patient’s circulating blood.
Now these small circular extracellular DNA fragments have been shown to be linked with cancer because they have lots of oncogenes on them, and because they lack normal chromatin structure and are of open conformation allowing the transcription machinery access to them so that their genes are always “on” and available for transcription.
