We have much better data on the impact of exposure during pregnancy for alcohol and tobacco, for sure, but we have emerging data for the impact of cannabis exposure.
I have to say, though, that all the research in that area is very difficult to conduct, just for ethical reasons. Obviously you cannot expose a woman and do a controlled placebo study, but the data we have now—from the human study from Brain Bank, for example, but also from animal models—show that cannabis can have some impact on brain development for the fetus and also in the long term. Obviously, as I said, the younger the exposure, including during the fetal life, the more important the long-term consequences can be.
Again, that research field is at its beginning, and it's a very difficult one to study for ethical reasons.
