Teenagers who smoke marijuana regularly achieve poorer grades at school and risk their chances of going to university, according to a major new scientific study.
A longitudinal study of more than 26,400 pupils in Canada found those who started using marijuana at least once a month were around half as likely to achieve high grades as they were before taking up the habit, and were ultimately less likely to pursue university ambitions.
Marijuana users were also four times more likely to skip classes and two-to-four times less likely to complete their homework and value getting good grades.
Proof cannabis DOES lead teenagers to harder drugs: Study finds users are 26 times more likely to turn to other substances by the age of 21
Teenagers who regularly smoke cannabis are 26 times more likely to turn to other drugs by the age of 21.
The study of the lives of more than 5,000 teenagers produced the first resounding evidence that cannabis is a gateway to cocaine, amphetamines, hallucinogens and heroin.
It also discovered that teenage cannabis smokers are 37 times more likely to be hooked on nicotine and three times more likely to be problem drinkers than non-users of the drug. The findings from Bristol University provide authoritative support for those warning against the liberalisation of drugs laws.

Ateenage rugby player cut off his own penis and stabbed his mother while high on skunk, his father has revealed, as he called for the drug to be reclassified.
The father, named only as Nick because he wants to remain anonymous as his son is rebuilding his life, is backing Lord Nicholas Monson's campaign to have skunk reclassified from a class B to a class A drug and for the traditional weaker form of cannabis to be decriminalised.
Lord Monson launched his call following the suicide of his 21-year-old son Rupert, who was addicted to skunk.
