How easy is it to get medical cannabis for anxiety and depression

weed has been helping me with both far more than any pill my dr subscribed to me. its like an ssri that actually works with a far lower chance of neurological side effects too with weed compared to ssris.

but i cant afford to keep buying it forever. manulife has been pretty good at covering things in my life up to this point so i was hoping theyd cover medical marijuana for that use.
