Dispute over study’s cannabis and IQ link

See on Scoop.itDrugs, Society, Human Rights & Justice

A widely-praised Dunedin, NZ study found people who started smoking cannabis in their teenage years, and kept using it for years afterwards, showed an average decline in IQ of eight points, however, a new study challenges this claim and suggests young teens who smoke cannabis may not be stunting their intellect.

Julian Buchanan‘s insight:

Like studies seeking to ‘prove’ links between cannabis and schizophrenia, the link with lower IQ is likely to have much more association with cultural and environmental factors (which can’t easily be factored out the equation) – rather than demonstrate any casual connection with cannabis.
