I usually use the bong after I already ate ao I can just focus on relaxing... Granted I just give it a couple of puffs so maybe that's why don't get big munchies
I would say nicotine is worse than cannabis, both can kill you sure. Cannabis have some great health benefits while idk any benefits of nicotine. And even if you die nicotine is worse since it's slower and more painful death rather than cannabis. Alcohol is obviously worse. But it might just be mine ignorance and lack of knowledge and experience with consuming both.
Nicotine itself is no more harmful than caffeine. Nicotine gum wont kill you, nicotine patches wont kill you. What kills you slowly and harmfully are all the other carcinogens and additives that are either in tobacco naturally or are added to cigarettes to preserve their flavor and freshness (and/or because tobacco companies seem to be literally evil sometimes, i actually have no idea how they can justify some of the toxic shit they add to cigarettes fo seemingly no reason).
Nicotine by itself is still quite bad for your heart/circulatory system, and it disrupts sleep and causes other nervous system issues. Yes inhaling combustion materials is worse, but nicotine is not harmless by any stretch.
