I want to just interject, if I may. Last week, we had Dr. Harold Kalant here from the University of Toronto, who both of you probably know. He said the following:
There is no such thing as a harmless drug. Everything with pharmacological action has the ability to produce harm, depending on the amount used, how often, for how long, by whom, and under what circumstances. Not surprisingly, the harmful effects of marijuana are most often found in heavier users and those with greater vulnerability.
Among those who begin to use marijuana as adults, the most common adverse effects include chronic inflammatory changes in the respiratory system, poor memory, poor work performance in activities requiring mental and physical skills, driving accidents, and addiction. The physical and mental effects usually recover on cessation of use.
But he went on to say:
...adolescents and young adult users of marijuana greatly outnumber mature adult users. Young beginners, those who begin use as early as 12 or 13 years, are much more vulnerable to harmful effects....
I want you to talk about that for a bit. We've talked about the medical use, but let's talk about the adolescents and the youth who come into this at age 12 or 13. How do we deal with them? How do we convince them that this is not to be used as a recreational drug as opposed to what you two are talking about with regard to the medical use? There are far different reaches there.
