From my understanding, in Germany it's not an authorized medication through their normal pathways. Medical cannabis is available through pharmacies on the basis of a doctor's prescription, and it is mandated to be covered for those who are on disability or welfare programs, so they do go a step further.
That said, a number of Canadian insurers have moved forward to cover medical cannabis, but it represents around 3% or 4% of the market who have any coverage, and 50% of those 3% or 4% have coverage beyond 50% of their dosage. We're really talking about a tiny fraction of the market with any coverage. Mainly this is attributed to what's known as “health spending accounts” in benefit plans that allow for medical cannabis to be claimed, but are typically capped at about $500 to $2,000 a year. That doesn't even come close to the full dose that someone with a chronic condition would need.
Insurers can cover the cost. There are a number of reasons why they don't, but given that reality, I think it's even more prudent for the government to look at this issue. This is a simple and rational decision that the government can make, to treat medical cannabis like every other medication. Especially in light of the lack of insurance coverage, this makes so much sense.
