The gateway drug theory (also called gateway theory, gateway hypothesis and gateway effect) states that the use of less deleterious drugs can lead to a future risk of using more dangerous hard drugs[1] or crime.[2] It is often attributed to the earlier use of one of several drugs including tobacco or alcohol or licit substances including cannabis.[1]
The reverse gateway theory posits that earlier regular cannabis use predicts later tobacco initiation and/or nicotine dependence in those who did not use tobacco before.[3]
Cannabis
The hypothesis is that the use of cannabis leads to other hard drugs via a sequence of stages.[1] This is based on the observation that many consumers who use cocaine or heroin have previously used cannabis, and most have used alcohol or tobacco; the hypothesis is that progression continues from there to other drugs like cocaine or heroin.[1] Some research supports that cannabis use predicts a significantly higher risk for subsequent use of "harder" illicit drugs, while other research does not.[1]
While some research shows that many hard drug users used cannabis or alcohol before moving on to the harder substances, other research shows that some serious drug abusers have not used alcohol or cannabis first.[1] The latter is evident in Japan, where the overwhelming majority of users of illicit drugs do not use cannabis first.[1] The risk factor for using drugs in cannabis users may be higher because few people try hard drugs prior to trying cannabis, not because cannabis users increasingly try hard drugs such as certain substituted amphetamines (e.g., methamphetamine). For example, cannabis is typically available at a significantly earlier age than other illicit drugs.
Jacob Sullum analyzed the "gateway" theory in a 2003 Reason magazine article, noting that the theory's "...durability is largely due to its ambiguity: Because it's rarely clear what people mean when they say that pot smoking leads to the use of "harder" drugs, the claim is difficult to disprove.":
- "Notice that none of these interpretations involves a specific pharmacological effect of the sort drug warriors seem to have in mind when they suggest that pot smoking primes the brain for cocaine or heroin. As a National Academy of Sciences panel observed in a 1999 report, 'There is no evidence that marijuana serves as a stepping stone on the basis of its particular drug effect.' Last year the Canadian Senate's Special Committee on Illegal Drugs likewise concluded that 'cannabis itself is not a cause of other drug use. In this sense, we reject the gateway theory.'"[4]
Alcohol and tobacco
Alcohol tends to precede cannabis use, and it is rare for those who use hard drugs to not have used alcohol or tobacco first; the 2005 National Survey of Drug Use and Health (NSDUH) in the United States found that, compared with lifetime nondrinkers, adults who have consumed alcohol were statistically much more likely to currently use illicit drugs and/or abuse prescription drugs in the past year.[5] Effects were strongest for cocaine (26 times more likely), cannabis (14 times more likely), and psychedelics (13 times more likely). In addition, lifetime drinkers were also six times more likely to use or be dependent on illicit drugs than lifetime nondrinkers.[5]
According to the NIDA, "People who abuse drugs are also likely to be cigarette smokers. More than two-thirds of drug abusers are regular tobacco smokers, a rate more than triple that of the rest of the population."[6]
Criticisms
Alternative explanations for the correlation between the use of soft drugs (e.g., marijuana) and the use of hard drugs (e.g., cocaine, heroin) include, but are not limited to:
- Some individuals are, for whatever reason, willing to try any substance, and the "gateway" drugs are merely the ones that are (usually) available at an earlier age than the harder drugs.
This article needs additional citations for verification. (December 2013) - For teenagers, credibility of adults is eroded when the dangers of the "gateway" drugs are exaggerated or made up, leading them to think all anti-drug messages are nonsense.[7]
- The peer environments in which "gateway" drugs are used can sometimes overlap with the ones in which harder drugs are used, especially in societies that prohibit the substances or impose very high age limits.[7]
