Yes, there are data. As I said, actually, it is quite clear, as Dr. Wood mentioned in some way.... The data for now shows that in general and for the general population the risk associated with cannabis actually is relatively minor in some ways, when someone is not vulnerable, but there are clearly some factors that would put people more at risk. As I mentioned, there's genetics, but clearly the age and youth....
One of the data we have now is about the cumulative consequences of exposure to cannabis. One of the factors that will actually increase the risk of having cognitive problems associated with cannabis is the age of exposure. Some studies that have been conducted are basically saying that when the exposure occurs before 15 or 16 years of age, the effect on cognition can be much more important and much more long term than when the exposure occurs at an older age, let's say, or in adulthood, for example.
