Nicotine has been widely accepted as a smoking cessation aid in the form of Nicotine Replacement Therapies (NRT) since the 1980s, and has been included in the World Health Organization’s List of Essential Medicines to treat ‘nicotine dependence’ since 2009.[1] But the therapeutic use of nicotine in medicine has a history – and potentially a future – that extends beyond its most common application. Research has indicated that nicotine could be a promising drug in managing and treating certain conditions, including Parkinson’s disease, Alzheimer’s disease, neurodivergences, and psychosis.
