Thank you very much, Madam Chair.
My colleague, Dr. Lunney, mentioned the study conducted by scientist Andra Smith, to whom I referred a bit earlier. As far as I understand, you were not familiar with that longitudinal and perinatal study.
I will give you some information related to my question. The study consisted of a 10-person subject group and a 14-person control group. I thought it was peculiar that three young individuals from the control group said they had consumed marijuana one to four times in the previous year.
I think discussions on marijuana do not make enough of a distinction between
heavy users, light users, and occasional users.
Mr. Lucas, you said in your presentation that about 40% of Canadians have consumed marijuana in the past. That's a fairly high percentage.
Can you tell us what portion of those people have consumed marijuana a few times in their life? What percentage of people consume it regularly, a few times a month? What percentage do heavy users account for?
I don't know what the criteria or categories are, or where the limit is. I would like to hear what you have to say about this, since 40% represents a lot of people.
