Gateway Drug Theory
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, while the correlated liabilities model argues that smoking and other drug use are predicated on genetic or environmental factors.

Famous quotes containing the words gateway, drug and/or theory:
“Antithesis is the narrow gateway through which error most prefers to worm its way towards truth.”
—Friedrich Nietzsche (1844–1900)
“Narcotics have been systematically scapegoated and demonized. The idea that anyone can use drugs and escape a horrible fate is an anathema to these idiots. I predict that in the near future, right wingers will use drug hysteria as a pretext to set up an international police apparatus.”
—Gus Van Sant, U.S. screenwriter and director, and Dan Yost. Father Tom Murphy (William S. Burroughs)
“A theory of the middle class: that it is not to be determined by its financial situation but rather by its relation to government. That is, one could shade down from an actual ruling or governing class to a class hopelessly out of relation to government, thinking of gov’t as beyond its control, of itself as wholly controlled by gov’t. Somewhere in between and in gradations is the group that has the sense that gov’t exists for it, and shapes its consciousness accordingly.”
—Lionel Trilling (1905–1975)
