Why does nicotine have a bad press?

The nicotine molecule is found naturally in numerous vegetables such as tomatoes, aubergines, and… tobacco leaves. It is often blamed for the harm caused by smoking. It is an alkaloid, a stimulant in small doses and may lead to strong dependence in the event of regular consumption, but is rapidly eliminated by the body and is not classified as CMR (carcinogenic, mutagenic and reprotoxic).
