I can understand the basis for those requirements in general (e.g. for antidepressants, doctors generally won't start you with an MAOI or a TCA, they'll start you with an SSRI or SNRI or similar, then try another one if that doesn't work, then maybe resort to TCAs if a couple of those don't work, then maybe try an MAOI if a couple of _those_ don't work), though I would agree that having a hard requirement of trying several other drugs first with the toxicity profile of cannabis seems...overly harsh at best. (Especially labeling people drug seekers for it - though they might be gun-shy after the fun with opioids and worried about finding a new epidemic of cannabis addicts, which seems...unlikely.)
