Likud –
The cRc is probably being machmir because they did not consider or do not agree with my point of the juice not being ???? ??????.
Also, I am less reluctant to rely on somewhat of a creative kula since – a) I follow a school of thought that holds the “kashrus sensitive ingredients” they are talking about are kosher anyway; and what is perhaps more relevant – b) at the end of the day, being concerned about Tosafos’s opinion is only a chumra; it is not the ikkar hadin.
It would seem from the cRc’s alert that they would have an issue with all types of e-cigarettes. Regular cigarettes are different, a) because “kosher sensitive ingredients” are much more rare; and b) because I’ve heard people ascribe to a line of reasoning that says that smoke from a non-kosher item is permitted to ingest even if vapor isn’t. I mentioned the basis for this in footnote 9 in the blog post.
