Is Thujone dangerous?

It depends on the ammount.

The FDA has imposed a 10mg per liter concentration limit
on all spirits containing Thujone,
and 35mg per liter for all the Bitters.
These are very low quantities and do not pose any threats to one’s health.
To begin feeling the effect of Thujone as a narcotic,
one would need to absorb 150mg or the equivalent of 15 bottles of spirit, as sold today.
Even this dose isn’t really dangerous; a lethal amount of Thujone,
for an individual weighing 80kg would be 80g…
