It is unclear whether the normative sequence of drug use initiation, beginning with tobacco and alcohol, progressing to cannabis and then other illicit drugs, is due to causal effects of specific earlier drug use promoting progression, or to influences of other variables such as drug availability and attitudes. One way to investigate this is to see whether risk of later drug use in the sequence, conditional on use of drugs earlier in the sequence, changes according to time-space variation in use prevalence. We compared patterns and order of initiation of alcohol, tobacco, cannabis, and other illicit drug use across 17 countries with a wide range of drug use prevalence. Analyses used data from World Health Organization WHO World Mental Health WMH Surveys, a series of parallel community epidemiological surveys using the same instruments and field procedures carried out in 17 countries throughout the world. Cross-country differences in substance use prevalence also corresponded to differences in the likelihood of individuals reporting a non- normative sequence of substance initiation. Community epidemiological research, concentrated in North America and Oceania, has documented a common sequence of drug use initiation that begins with tobacco and alcohol use, followed by cannabis and then other illicit drugs. Some commentators have argued that the gateway pattern is due to a causal effect of earlier substance use on use of later substances Fergusson et al. A variety of pathways have been proposed, some more reductionist than others. One suggestion for a gateway effect of cannabis use on subsequent opioid use, for example, is that cannabis alters the opioid system in the brain, leading to a change in hedonic processing that promotes subsequent opioid use Ellgren et al. If true, such causal effects of earlier substances in the gateway sequence on subsequent use of later substances would suggest that efforts to prevent use of specific earlier drugs might help reduce initiation of the later ones. However, the gateway pattern observed in epidemiological data is also consistent with the existence of one or more unmeasured common causes, such as a risk-taking predisposition and latent propensity to use drugs as just one of a range of risk behaviours, rather than a causal effect of earlier gateway drugs Morral et al. If common causes account for the gateway pattern, then we would not expect prevention of use of specific earlier drugs in the sequence to cause a reduction in use of later substances. Debate about these possibilities continues Fergusson et al. One approach to investigating this issue that has not been pursued in the past is to examine data on time-space variation in use of drugs earlier and later in the gateway sequence. An analogous approach was presented by Weiss et al. These studies suggest that the association between cocaine and tobacco use and mood disorders may not be a simple causal one; and perhaps that the prevalence of drug use might impact upon associations with other variables. Conversely, if associations between the use of a drug and other outcomes such as psychiatric disorders or other drug use were causal , we would expect changes in prevalence of one drug to have no impact on associations with later outcomes e. The Weiss et al. This implies that some external sociocultural factors influenced changes in prevalence of use, with the difference in prevalence due to reasons that would not be expected to influence the outcomes under study other than through exposure to cocaine. This assumption is formalised in the econometric method of instrumental variables analysis, in which a causal determinant of a putative risk factor is found, which can be assumed not to have any direct causal effect on an outcome other than through the risk factor Pearl, When such an instrument is found, it can be used to estimate the magnitude of the causal effect of the risk factor on the outcome in such a way as to separate out any bias due to reciprocal causation or unmeasured common causes. The classic case in economics was the use of information about forest fires in Northwest USA, and railroad strikes, to influence the price of lumber, which in turn influenced the number of new housing starts. We know, for example, that US tobacco use dropped dramatically in the s, due to a combination of public education campaigns and aggressive taxation policy, influences that would not be expected to have any direct effect on use of cannabis or other illicit drugs other than through the effect of reducing tobacco use. Was this reduction in tobacco use accompanied by the reduction in use of illicit drugs that would be predicted by the gateway theory? We are unaware of any direct analysis of epidemiological data aimed at answering that question. We present this type of analysis here. Rather than focus on a single country in a single time period though, we present cross-national comparisons, combining information about between-country differences with information about within-country through-time variation, to examine broad patterns of association. No attempt is made to measure explicit instrumental variables. Instead, we work on the implicit assumption that the time-space variation in prevalence of earlier so-called gateway drugs alcohol, tobacco and cannabis reflects factors that would not be expected to influence use of later drugs directly. Cross-national data can provide some information on this issue, as the prevalence of licit and illicit drug use varies dramatically across countries and cultures. Alternatively, if there was variation in both levels and associations across countries, this would support the putative influence of other variables on the association. Some limited data exist on this issue. Rather, it was prior cumulative exposure to total drugs, and an earlier onset of initiation, that were significant predictors of transition to dependence. It would be useful to extend these results to a larger set of countries with a wider range of variation in drug use to consider the consistency of the order of initiation of drug use, and observe whether associations between use of one drug and initiation of another are consistently observed. The current paper presents the results of such an extension using the World Health Organization WHO World Mental Health WMH Surveys, a series of parallel community epidemiological surveys using the same instruments and field procedures that were carried out in 17 countries throughout the world. The aims of this study are to:. The total sample size was 85,, with individual country sample sizes ranging from the Netherlands to 12, New Zealand. The weighted average response rate across countries was All surveys were based on probability household samples of adults that were either representative of particular regions of the country in China, Colombia, Japan, and Mexico or nationally representative other countries. Table 1 presents sample characteristics for the WMHS. Most WMH surveys are based on stratified multistage clustered area probability household samples in which samples of areas equivalent to counties or municipalities in the US were selected in the first stage followed by one or more subsequent stages of geographic sampling e. No substitution was allowed when the originally sampled household resident could not be interviewed. These household samples were selected from Census area data in all countries other than France where telephone directories were used to select households and the Netherlands where postal registries were used to select households. Several WMH surveys Belgium, Germany, Italy used municipal resident registries to select respondents without listing households. The Japanese sample is the only totally un-clustered sample, with households randomly selected in each of the four sample areas and one random respondent selected in each sample household. Nine of the 15 surveys are based on nationally representative NR household samples, while two others are based on nationally representative household samples in urbanized areas Colombia, Mexico. The response rate is calculated as the ratio of the number of households in which an interview was completed to the number of households originally sampled, excluding from the denominator households known not to be eligible either because of being vacant at the time of initial contact or because the residents were unable to speak the designated languages of the survey. The weighted average response rate is All interviews were conducted face-to-face by trained lay interviewers. Each interview had two parts. The Part II interview assessed correlates, service use, and disorders of secondary interest to the study. The assessment of substance use patterns was included in Part II. The Part II survey data were weighted to adjust for the over-sampling of people with mental disorders and for differential probabilities of selection within households, as well as to match samples to population socio-demographic distributions, making the weighted Part II samples representative of the populations from which they were selected. Standardised interviewer-training procedures, WHO translation protocols for all study materials and quality control procedures for interviewer and data accuracy were consistently applied across all WMH countries in an effort to ensure cross-national comparability. These procedures are described in more detail elsewhere Alonso et al. Informed consent was obtained before beginning interviews in all countries. Procedures for obtaining informed consent and protecting human subjects were approved and monitored for compliance by the Institutional Review Boards of the organizations coordinating the surveys in each country. Mental and substance disorders were assessed with Version 3. Participants were separately asked if they had ever used tobacco, alcohol, cannabis and other illicit drugs. Different onset orders, as determined by retrospective age-of-onset reports were evaluated. Violations of the gateway progression were defined as:. Violation 2: First use of other illicit drugs cocaine, heroin, opium, glue, LSD, peyote, or any other drug before alcohol and tobacco;. Violation 3: First use of other illicit drugs cocaine, heroin, opium, glue, LSD, peyote, or any other drug before cannabis. In order to examine whether a less stringent text of the gateway sequence may have produced different results, we examined use of cannabis before either alcohol or cannabis use i. Although violations of this sort were more common, the pattern of findings was similar Supplementary Tables 1a , 2a , 3 1. Cumulative prevalence of drug use and gateway violations by age 29 were estimated for each country and cohort, with standard errors derived using the Taylor series linearisation TSL methods implemented in SUDAAN to adjust for the effects of weighting and clustering on the precision of estimates. The associations of the onset of substances earlier in the gateway sequence with the subsequent first onset of the later drug in the sequence were estimated using discrete time survival analysis with person year as the unit of analysis within country and controlling for person year and sex. Discrete-time survival models pooled across countries were run to include the interaction between use of each gateway drug category and the prevalence of gateway drug use within each country. Covariates included, gender, age cohort, and country. Drug use by age 29 years by age group at interview is presented in Table 2 for all 17 countries. South Africa had the lowest level of alcohol use, with Tobacco use was relatively rare in South Africa Cannabis use was very low in Nigeria 2. Despite relatively low rates of alcohol and tobacco use, South Africa showed moderate prevalence of cannabis use 8. In Japan, the use of other illicit drugs by age 29 years was more prevalent than cannabis Table 2. Age cohort differences in drug use were common: most countries showed increases in prevalence of use of all drugs among younger cohorts. Prevalence of drug use by age 29 years, according to age group at interview. Chi square tests examined associations between the prevalence of drug use by age 29 and age at the time of interview. Prevalence results were not obtained and therefore the chi-square test was not performed. Other illicit drugs included cocaine and other drugs. Prescription drugs are not included in the definition of other illicit drugs. Projected cumulative estimates for prevalence of respondents less than 29 years of age at interview. Since n is zero or small for some cells, they were collapsed so that the chi-square test could be executed. However, the strength of these associations differed across countries. For example, cannabis use was less strongly associated with later illicit drug use cocaine and other illicit drugs among young adults yrs in the Netherlands than it was in Belgium, Spain and the United States. Association between the initiation of a drug and the later use of other drugs by 29 years, according to country and age cohort. Results are based on discrete time survival models with person-year as the unit of analyses. Person-year and sex are used as a control. Analysis was omitted due to zero or too few outcomes that model could not converge. Other illicit drugs include cocaine and other drugs. Estimated prevalence of violations to the gateway sequence among drug users in each of the 17 countries is presented in Table 4 and Supplementary Tables 1 and 2. Cannabis users in South Africa, a country with the lowest rates of both alcohol and tobacco use, showed the highest rate of violating the typical gateway sequence, with Among other illicit drug users, Japan had the highest rate of violating the gateway sequence, with Nigeria had the second highest rate, with Percent of those using other illicit drugs 4 by age 29 years who had NOT already used cannabis before beginning other illicit drug 4 use, by country and age at interview. Cannabis was rarely used before other illicit drugs by most other illicit substance users in countries where cannabis use was rare Japan In countries where rates of cannabis use were highest, violations to the gateway sequence were uncommon U. Rather, it was the number of drugs used, and an earlier onset of exposure to drugs overall , that predicted transition to dependence Table 5 , Supplementary Table 3a.

This is a time-varying covariate and refers to the number of illicit drugs grouped as cannabis, cocaine, prescription drugs or other drugs the person had used by a given year. The present paper examined the extent and ordering of licit and illicit drug use across 17 disparate countries worldwide. This comparison, using surveys conducted with representative samples of the general population in these countries, and assessment involving comparable instruments, allowed for the first assessment of the extent to which initiation of drug use follows a consistent pattern across countries. Previous studies, concentrated in high income countries with relatively high levels of cannabis use, have documented: a common temporal ordering of drug initiation; an increased risk of initiating use of a drug later in the sequence once having initiated an earlier one; and the persistence of the association following controlling for possibly confounding factors Kandel et al. The present study supported the existence of other factors influencing the ordering and progression of drug use because 1 other illicit drug use was more prevalent than cannabis use in some countries, e. This finding is contrary to the assumption that initiation reflects a universally ordered sequence in which rates of drug use later in the sequence must necessarily be lower than those earlier in the sequence Kandel, This has not previously been reported as research has been traditionally conducted in countries where use of tobacco, alcohol and cannabis is relatively common. Thus, while previous studies have consistently documented that the use of an earlier substance in the gateway sequence predicts progression to use of later substances Grau et al. The most common gateway violation was that of other illicit drug use before cannabis. Higher levels of other illicit drug use before cannabis were related to lower levels of cannabis use in these countries Japan and Nigeria. Similarly, first use of other illicit drugs before alcohol and tobacco was found to be most prevalent in Japan and Nigeria, countries with relatively low rates of alcohol and tobacco use compared to other WMHS countries Degenhardt et al. In contrast, use of cannabis before alcohol and tobacco was extremely rare in countries with some of the highest rates of cannabis use, such as the US and New Zealand. Cannabis users in the US were also much more likely to progress to other illicit drug use than those in the Netherlands. Taken together, cross-country differences in drug use prevalence corresponded remarkably well with differences in the prevalence of gateway violations. What are the implications of these findings for our understanding of the relationship between the initiation of drug use and potential adverse drug-related outcomes later in life? First, consistent with other discussions of early onset drug use Iacono et al. Rather, consistent with a number of lines of observational evidence, many involving prospective study designs see Iacono et al. This was lent support in this study through the finding that the number of early onset mental disorders prior to age 15 years was an important moderator of risk for developing dependence. The finding that adolescents with externalising and internalising disorders were at elevated risk of developing drug dependence is consistent with prospective cohort studies, which have found that early onset drug use and mental health problems are risk factors for later dependent drug use Toumbourou et al. It also suggests that, rather than focusing on specific patterns of initiation, or on the use of particular drugs in order to prevent transitions to other specific drug use or dependence, prevention efforts are probably better targeted at all types of drug use, particularly among young people who are already dealing with other challenges or risk behaviours, since it may be this group that is most at risk of developing problems later on. As with all cross-sectional survey research it needs to be noted that the WMHS surveys were not explicitly designed to answer the current research question , there are several limitations that should be considered. First, this study found cohort differences in substance use within various countries as well as cohort differences in the order of onset of use. Although this may reflect actual cohort differences, they may also reflect response biases. Retrospective reporting of age of first substance use is subject to error, given that respondents are being asked about events that, for older persons, may have occurred decades ago. Longitudinal studies have found that estimates of the age of first use do tend to increase upon repeat assessment i. There might be differential social stigma and legal practices in each country affecting self-reported drug use. Attempts were made to ensure truthful, honest answers were provided by participants in these surveys in four major ways. First, pilot testing in each country was carried out to determine the best way to describe study purposes and auspices in order to maximize willingness to respond honestly and accurately. Second, in countries that do not have a tradition of public opinion research, and where the notions of anonymity and confidentiality are unfamiliar, we contacted community leaders in sample sites to explain the study, obtain formal endorsement, and have the leaders announce the study to community members and encourage participation. The announcements were most typically made by religious leaders as part of their weekly sermons, although there are other cases, such as the formal community leaders in each neighbourhood in Beijing and Shanghai, where secular community leaders who were given presents by the study organizers made formal announcements and encouraged members of their neighbourhood to participate in the survey. Third, interviewers were centrally trained in the use of non-directive probing, a method designed to encourage thoughtful honest responding. Finally, especially sensitive questions were asked in a self-report format rather than an interviewer-report format, although this could be done only for respondents who could read. These methods were doubtlessly not completely effective in removing cross-national differences in willingness to report, though, so it is important to recognise the possible existence of remaining differences of this sort in interpreting cross-national differences in results. It needs to be noted that the comparisons used in this paper were very conservative for several reasons. Different countries are comprised of differing ethnic, religious and other social groupings, which are highly likely to affect the prevalence of drug use. We were not able to directly control for these groupings in a consistent way across countries. Future research might examine whether some of the differences in the levels of use and possibly in the order of initiation might be related to ethnicity and religious affiliation. The second reason reflects the measurement of drug use. We selected any use of a drug as the prior exposure variable when considering the gateway sequence of initiation. Future work might examine the relationship between onset of regular use to examine whether the same relationships still hold as observed in the analyses presented here. A more focused approach could also be used to study one place and interval of time to measure explicitly a single instrumental variable, such as a change in cigarette taxation rates, to estimate the effects of cigarette use on later substance use. The next step in this line of research should consequently be to undertake focused analyses. Despite these limitations, the present study is the first to describe cross-national associations between substances in the order of initiation of drug use, based on largely comparable sampling strategies and assessment tools. The most notable advantage of the WMHS is that these surveys represents 17 large, nationally representative and regionally diverse samples, and cover a wide range of ages and hence birth cohorts, over a period of changing drug markets and country specific social norms related to drug use. The present study provided suggestive evidence to suggest that drug use initiation is not constant across contexts and cultures. Although cannabis is most often the first illicit drug used, and its use is typically preceded by tobacco and alcohol use, the variability seen across countries, which is related to the background prevalence of such drug use, provides evidence to suggest that this sequence is not immutable. Violations of this sequence are not associated with the development of dependence; rather, it seems to be the age of onset and degree of exposure to any drugs that are more important predictors.
