Cannabis linked to school drop outs

A new study of cannabis use has found that those who use the drug before the age of 17 are 2/3s more likely to drop out of school. It was also found that suicide attempts among cannabis users are 7 times more likely.

The study was carried out by a team of Australian and New Zealand researchers.
It involved an analysis of data from more than 3,700 cannabis users.

The study shows cannabis users are more likely to become dependent on cannabis later in life.
Other long term effects can result in memory loss ,psychosis & or depression. And Has also found that users are 18 times more likely to become addicted to cannabis and or harder drugs

Cannabis has many different effects on different users , depending on what strain or THC levels
its really a mystery as to how it affects each of us, as each human has different immune systems.
Leading to different reactions.

I remember many moons ago, i took a puff of cannabis for first time ever time, without eating breakfast or anything,  I collapsed before passing that doobie on the left hand side.

Summary

Background

Debate continues about the consequences of adolescent cannabis use. Existing data are limited in statistical power to examine rarer outcomes and less common, heavier patterns of cannabis use than those already investigated; furthermore, evidence has a piecemeal approach to reporting of young adult sequelae. We aimed to provide a broad picture of the psychosocial sequelae of adolescent cannabis use.

Methods

We integrated participant-level data from three large, long-running longitudinal studies from Australia and New Zealand: the Australian Temperament Project, the Christchurch Health and Development Study, and the Victorian Adolescent Health Cohort Study. We investigated the association between the maximum frequency of cannabis use before age 17 years (never, less than monthly, monthly or more, weekly or more, or daily) and seven developmental outcomes assessed up to age 30 years (high-school completion, attainment of university degree, cannabis dependence, use of other illicit drugs, suicide attempt, depression, and welfare dependence). The number of participants varied by outcome (N=2537 to N=3765).

Findings

We recorded clear and consistent associations and dose-response relations between the frequency of adolescent cannabis use and all adverse young adult outcomes. After covariate adjustment, compared with individuals who had never used cannabis, those who were daily users before age 17 years had clear reductions in the odds of high-school completion (adjusted odds ratio 0·37, 95% CI 0·20—0·66) and degree attainment (0·38, 0·22—0·66), and substantially increased odds of later cannabis dependence (17·95, 9·44—34·12), use of other illicit drugs (7·80, 4·46—13·63), and suicide attempt (6·83, 2·04—22·90).
