Chronic exposure to cocaine activates a stress response, which activates the over expression of the JNK gene.
Cocaine with fibro is a double "whammy". Pathogenic mycoplasma infections causing FMS ( mycoplasmas can take over the immune system ) and a huge disease menu caused by prolonged JNK gene activation from cocaine use -primary- and other factors-secondary- as follows:
JNK activated conditions.
Cancer of all type
Neurotransmitters no longer function properly
Within the above list and the autoimmune/neuro-systemic diseases caused by pathogenic mycoplasmas, the answer is yes, very possible.
Hope this answers your question.
