I agree with the writer, she deserves adequate and effective treatment for her condition.
She will be HABITUATED to her medications, in other words, she is dependent on them , and would suffer withdrawal symptoms if the were stopped suddenly. She is likely not ADDICTED to them, in other words, she is not escalating her dose to get high, and she is not cutting the patches open to suck on the fentanyl inside (yes it happens). Probably something bad would happen to a diabetic quitting insulin also.
She is not contributing in any way whatsoever to the Fentanyl overdose epidemic, and neither is her doctor.
The academics writing up these ridiculous ivory tower guidelines are well shielded from the real world of patients with disabling pain, and so are the Registrars of the various Colleges of Physicians imposing these unrealistic "guidelines". By the way , they are no longer guidelines , but diktats to be followed at the peril of losing your licence. Good luck Canada.
