To the Editor: I would like to point out 2
defects in the study of Dr Solowij et al. First, it does not control for age-related
differences in cognitive function, which could potentially cause the differences
between the long- and shorter-term user groups. Second, cannabinoids are present
for many days after ingestion. Age-related differences in excretion may also
explain the apparent difference in function between long- and shorter-term
users of marijuana.
