Using nicotine pouches (snus)

Andrew Huberman discusses the implications of using nicotine, including nicotine pouches, which are an alternative method for nicotine intake. He highlights that while nicotine can enhance cognitive function in the short term, it has side effects independent of its delivery method, such as smoking or vaping. Specifically, using forms like dipping or chewing tobacco, similar to snus, is associated with a significant increase in the risk of mouth cancers and other health issues. Therefore, these methods of nicotine delivery are not recommended due to their severe health risks 1.

Moreover, he suggests that for adults over 25, using nicotine might have some cognitive benefits provided it is ingested in controlled doses and not used excessively. However, for younger individuals, particularly those under 25, avoiding nicotine is advisable due to the risk of developing nicotine dependence and the potential negative impacts on brain development and overall health 1.
