Q. Is there a problem of Sheviis with hadassim – can I use them for besomim in havdolah?

A. Sefer Hashmitta (from HagrI”M Tikotinsky zt:l, 7: 4: 6) mentions that hadasim like the lulav and arovos, do not acquire the holiness of sheviis, since they are mainly planted with the intention of being used for their mitzvah, therefore they could also be used for smelling purposes. He also quotes a similar opinion from Tzitz Hakodesh (1: 15) in the name of Maharil Diskin. Nesiv Hashmita quotes an analogous view in the name of the Chazon Ish. Although Chut Hashani maintains that the minhag of people is to be lenient, some are machmir. Yalkut Yosef (Mitzvos Hatluyos Ba’aretz p.444) quotes dissenting opinions at to what the opinion of the Chazon Ish is. and also quotes some Poskim that are stringent.
Horav Shlomo Miller’s Shlit”a opinion is to be lenient.
