The relationship between tobacco and other drug use has been well-established, however the nature of this association remains unclear. The two main theories are the phenotypic causation (gateway) model and the correlated liabilities model. The causation model argues that smoking is a primary influence on future drug use,[119] while the correlated liabilities model argues that smoking and other drug use are predicated on genetic or environmental factors.[120]
