Can I Use Expired Nicotine Lozenges

I have taken nicotine lozenges but the expiration date is 08/08, are they still okay? Aren't they open? 3

Affiliation with nicotine gum

Medications usually remain valid for some time, even after a certain expiration date. However, after 2 years a drug may be ineffective and sometimes chemically altered, producing harmful substances. I strongly recommend not using it.
