Nicotine (smoking) has been known to act as an immunomodulator and can act as a preventative for gastrointestinal inflammatory disease such as ulcerative colitis. This could be attenuating the inflammatory response and reducing symptoms for COVID-19 patients.

Perhaps the additives are keeping COVID-19 patients alive by supporting breathing in difficult circumstances? There are hundreds of additives so figuring out if any of them help would be difficult:
