Absinthe offered for sale in the United States must be thujone-free by the same standard that applies to other beverages containing ''Artemisia'',<ref name =ttb /> so absinthe with small amounts of thujone may be legally imported.

===Canada===
In Canada, liquor laws are the domain of the provincial governments.  Alberta, Ontario, and Nova Scotia allow 10&nbsp;mg/kg thujone; Quebec allows 15&nbsp;mg per kg;{{Citation needed|date=April 2007}} Manitoba allows 6–8&nbsp;mg thujone per litre; British Columbia adheres to the same levels as Ontario. However, in Saskatchewan and Quebec, one can purchase any liquor available in the world upon the purchase of a maximum of one case, usually 12 750-ml bottles or 9&nbsp;L. The individual liquor boards must approve each product before it may be sold on shelves.
