“…Benson and Holmberg assessed the validity in the Gothenburg part of the same national conscription survey and found that conscripts generally gave correct information concerning drug use and abuse. 19 Rydelius compared data on alcohol consumption obtained by structured in depth interviews of 1004 18 year olds and data obtained anonymously from the same group in the conscription survey during the same year and found a good correlation.20 The strong association between the reported alcohol consumption at conscription and the incidence of treatment for alcoholism during follow up lends further support to the assumption that the selfreported level ofalcohol consumption in this cohort was reliable.…”

The association between alcohol consumption and 15 year mortality was studied in a cohort of 49 464 Swedish conscripts, mostly aged 18-19. A strong association was found. The relative risk of death among conscripts with a high consumption of alcohol (>250 g/week) was 3-0 (95% confidence interval (2.3 to 4-1) compared with those with moderate consumption (1-100 g/ week). After adjustment for social background variables the relative risk was reduced to 2-1 (95% confidence interval 1*4 to 3-2). Among causes of death a strong predominance was found for violent death, suicide or probable suicide being the leading single cause and accounting for 236 (36%) of all deaths. The reported U shaped curve for total mortality was not confirmed, though when violent deaths were excluded a U shaped curve was suggested for other causes of death.These findings provide important epidemiological data on the drinking habits of young people and the consequences for mortality.

“…Under-reporting of problematic alcohol and cannabis use could lead to underestimation of relative risks for adult alcohol and drug abuse. Although Benson & Holmberg found that conscripts generally gave correct information concerning problematic alcohol and cannabis use [44], we still do not know how representative are the habits reported at conscription for the follow-up period. In this study, the habits at a young age have to be regarded as predictors for the longitudinal perspective.…”

Drug and Alcohol Review

The aim of this longitudinal study was to investigate the problematic use of alcohol, cannabis or both in adolescence, identifying various risk factors for adult alcohol and drug abuse. The study included 7,577 18-year-old men conscripted in 1969-70. At enrollment, they completed two questionnaires about alcohol and drug use, social background, behavioural factors and health conditions. Data on adult alcohol and substance abuse were obtained from official registers up to 1996. A combination of problematic alcohol use and cannabis use in adolescence (>10 times) was associated more strongly with both adult alcohol abuse (RR=6.56, 95% CI 4.24-9.83) and drug abuse (RR=19.37, 95% CI 11.16-32.30) than adolescent use of cannabis or alcohol alone. When stratifying for different risk factors, the combination of both problematic alcohol use and cannabis use had higher relative risks of both outcomes than alcohol or cannabis use alone. In multivariate analyses, tobacco smoking was associated most strongly (RR=2.26, 1.58-3.24) with adult alcohol abuse, and a combination of problematic alcohol use and cannabis use (<10 times) in adolescence was associated most strongly with adult drug abuse (RR=5.60, 95% CI 2.92-10.75). Adolescent use of both cannabis and alcohol seems to be a more serious problem than adolescent use of either alcohol or cannabis alone with regard to escalation to adult alcohol and drug abuse. This is important knowledge for prevention of adult abuse. Special effort should be made to reach those who mix risky alcohol use and cannabis use in late adolescence.

“…28 Consequently, self-reported cannabis use is likely subject to under-reporting. On the contrary, studies of the same group of Swedish conscripts have shown that the young men generally gave correct information on their drug use, 29 suggesting that the material is valid for epidemiological analysis. Because this study only included men in Sweden born around 1950, the generalizability is limited.…”

Background and Purpose-Current knowledge on cannabis use in relation to stroke is based almost exclusively on clinical reports. By using a population-based cohort, we aimed to find out whether there was an association between cannabis use and early-onset stroke, when accounting for the use of tobacco and alcohol. Methods-The cohort comprises 49 321 Swedish men, born between 1949 and 1951, who were conscripted into compulsory military service between the ages of 18 and 20. All men answered 2 detailed questionnaires at conscription and were subject to examinations of physical aptitude, psychological functioning, and medical status. Information on stroke events up to ≈60 years of age was obtained from national databases; this includes strokes experienced before 45 years of age. Results-No associations between cannabis use in young adulthood and strokes experienced ≤45 years of age or beyond were found in multivariable models: cannabis use >50 times, hazard ratios=0.93 (95% confidence interval [CI], 0.34-2.57) and 0.95 (95% CI, 0.59-1.53). Although an almost doubled risk of ischemic stroke was observed in those with cannabis use >50 times, this risk was attenuated when adjusted for tobacco usage: hazards ratio=1.47 (95% CI, 0.83-2.56). Smoking ≥20 cigarettes per day was clearly associated both with strokes before 45 years of age, hazards ratio=5.04 (95% CI, 2.80-9.06), and with strokes throughout the follow-up, hazards ratio=2.15 (95% CI, 1.61-2.88). Conclusions-We found no evident association between cannabis use in young adulthood and stroke, including strokes before 45 years of age. Tobacco smoking, however, showed a clear, dose-response shaped association with stroke.
