Associate Professor, University of British Columbia, As an Individual

Dr. Zach Walsh

Well that's actually a common side effect of most anxiolytic or anti-anxiety medications—

9:25 a.m.

I understand that.

Associate Professor, University of British Columbia, As an Individual

Dr. Zach Walsh

—so some increasing anxiety is reported by some cannabis users as part of the short-lived withdrawal syndrome. It's more short-lived than withdrawal syndromes associated with benzodiazepines or barbiturates, which are less widely used now.

9:25 a.m.

Conservative

That's true, thank you.

You mentioned for some reason that marijuana users who also smoke cigarettes, or nicotine, actually have better academic performance than those who smoke cigarettes alone.

9:25 a.m.

Associate Professor, University of British Columbia, As an Individual

Dr. Zach Walsh

Yes, that's right.

9:25 a.m.

Conservative

I'm trying to understand why you would raise that. It seems to me you're trying to connect marijuana with better academic performance, which is ludicrous because the primary effects of marijuana are euphoria, memory loss, and apathy. If you want to destroy a student's future, probably the best drug you could give them is marijuana because it ruins their memory; they can't learn anything in school, and it causes apathy and they won't care.

Why are you trying to connect marijuana to better academic performance?

9:25 a.m.

Associate Professor, University of British Columbia, As an Individual

Dr. Zach Walsh

I'm certainly not saying that I would recommend it as an academic enhancer. As an educator, that's certainly not something that I'm interested in doing.

9:25 a.m.

Conservative

Terence Young Conservative Oakville, ON

Okay, it's good to hear that.

9:25 a.m.

Associate Professor, University of British Columbia, As an Individual

Dr. Zach Walsh

Rather, I'm referring to the results of the study that showed that in people who used both cannabis and tobacco, compared to tobacco alone, we see worse outcomes among the tobacco users. It has to do with the increased stigmatization of tobacco use.

9:30 a.m.

Conservative

Terence Young Conservative Oakville, ON

So your position is that it's the lesser of two evils.

9:30 a.m.

Associate Professor, University of British Columbia, As an Individual

Dr. Zach Walsh

Well, not exactly. I think it reflects the confounding effects of people who use one or both.

9:30 a.m.

Conservative

Terence Young Conservative Oakville, ON

You also claim there's no rise in psychotic disorders, which is contradicted by the medical experts and pharmacologists. We heard from them that marijuana can lead to depression, and we know there's been a very significant rise in youth suicide in recent years. Have you studied the relationship between suicide and marijuana?

9:30 a.m.

Associate Professor, University of British Columbia, As an Individual

Dr. Zach Walsh

I don't know of any evidence to suggest that marijuana leads to increased suicide.

9:30 a.m.

Conservative

Terence Young Conservative Oakville, ON

Have you studied it?

9:30 a.m.

Associate Professor, University of British Columbia, As an Individual

9:30 a.m.

Conservative

Terence Young Conservative Oakville, ON

Do you know anyone who has?

9:30 a.m.

Doctoral Candidate, University of Victoria, As an Individual

Philippe Lucas

Yes. There is a study in the U.S. that shows a decrease in suicides in states with medical marijuana. They assume it's because of less suffering and the suffering that's relieved by it.

You also mentioned higher income and academic achievement. In Canadian polling of medical cannabis users, Canadians who use marijuana have higher income levels and higher education levels than those who don't use cannabis.

9:30 a.m.

Conservative

Terence Young Conservative Oakville, ON

Whoa, are you trying to claim that marijuana leads to higher income levels?

9:30 a.m.

Doctoral Candidate, University of Victoria, As an Individual

Philippe Lucas

I'm saying those are the facts according to all polling—

9:30 a.m.

Conservative

Terence Young Conservative Oakville, ON

What a ludicrous connection. Come on, let's be scientific.

9:30 a.m.

Doctoral Candidate, University of Victoria, As an Individual

Philippe Lucas

It's not a ludicrous connection at all.

9:30 a.m.

Conservative

Terence Young Conservative Oakville, ON

I don't believe it for one second, by the way.

9:30 a.m.

Doctoral Candidate, University of Victoria, As an Individual

Philippe Lucas

You don't need to believe it, but those are the stats. Those are the facts. It's not a belief system; it's a fact.

9:30 a.m.

Conservative

Terence Young Conservative Oakville, ON

Say that again for the record.

9:30 a.m.

Doctoral Candidate, University of Victoria, As an Individual

Philippe Lucas

Those are the facts.
