    The only thing I would add is that the measures were not standard IQ tests but rather tests of attention, memory, and executive (frontal lobe) function.

    The Dunedin data found no evidence of any relationship between adult cannabis consumption and cognitive function, but identified adolescent use as a risk factor for lower adult cognitive function. The authors offered up a critical period hypothesis to account for the effects. It is a bit like exposure to mercury or lead during neonatal development has profound effects on neurological function in later life. The problem with failing to adjust for socioeconomic status is that many factors known to impair neurological development during the critical period are associated with SES, including nutrition, toxic exposures, stress, and addictive substance abuse.

    Be radical in your compassion.
