Are vanilla bean seeds viable?
 
From grocery store vanilla beans? (for practicing orchid embryo culture)

Now that's an interesting question.... I'd assume since the pod is
sorta dried the seeds aren't viable anymore, but hey, you don't know
until you try. Orchids are tough plants. I'd also wonder if teh
manufacturer might treat the pod chemically to prevent fungus or other
rotting and prolong shelf-life. But really I have no idea.

According to the Wiki article on vanilla Vanilla - Wikipedia, the free encyclopedia the pods are "killed" by heat treatment as the first stage of processing after harvesting.

Even if the seeds are obtained from pre-treated pods they are very
difficult to pollinate.

Vanilla pods can be smoked! Has anyone tried it?

As I recall, fermentation of the capsule is part of the preparation of
commercial vanilla. If so, I would expect the embryos to be
non-viable, and in any event, it would be next to impossible to
disinfect them.

The flavor industry, in particular, is especially interested in
understanding the formation of the typical vanilla flavor complex from
the tasteless precursors present in the green bean, and much effort
has gone into the analysis of the volatile components of the cured
brown vanilla bean.

Of specific interest to us was the elucidation of the fate of the
vanillin during the traditional curing process, once it has been
liberated via endogenous enzymatic hydrolysis of the corresponding
glycoside, glucovanillin. It is known that physical losses occur
during a number of the steps that are inherent to the traditional
fermentation and drying process, and chemical losses occur via
oxidative conversion into structurally related materials during the
monthlong curing process.2 Other chemical losses are due to its
participation in the Maillard reaction, a process that gives the cured
beans their typical dark brown color.
