Madam Speaker, I am pleased to speak again to Bill C-45 now that it is at the report stage, having previously commented on certain aspects of the bill at the second reading stage. I will not go over that again, but I would like to address certain elements that were changed in committee, especially the 100-centimetre limit on plant height, which seemed a bit arbitrary to me. I could not understand where that number had come from.
In committee, experts told us this limit might actually backfire, because shorter plants tend to have higher concentrations of THC, producing stronger psychoactive effects. The 100-centimetre limit was therefore removed, which was a good thing.
In committee, it also became clear that the Liberal government is not interested in getting the best bill possible. It was so partisan that when the NDP proposed an amendment to eliminate the 100-centimetre limit, the Liberals insisted on voting it down and proposing their own version a few minutes later saying the exact same thing, just because they did not want us to beat them to the punch. That may not be the best way to treat such a serious issue. I am disappointed.
Initially, we did not plan for edible products to be allowed, but this has changed. We will allow them but only in one year. I would like to speak to this particular issue, which I believe is quite important.
Dried cannabis has to be smoked, which is toxic for the lungs. Any inhaled smoke has a certain degree of pulmonary toxicity, whether it comes from a cattail or a cigarette. However, according to the studies I have read, cannabis smoke is apparently 10 times more toxic for the lungs than tobacco smoke. Let me be clear: I am not telling people to smoke cigarettes. All I am saying is that cannabis is highly toxic for the lungs when it is inhaled.
Thus, by allowing that substance to be included in food, we would at least eliminate the issue of pulmonary toxicity. In spite of that, it was decided to allow people to smoke cannabis before allowing them to eat it, which is illogical. Many people in my riding did not understand why people were being encouraged not to smoke tobacco just about everywhere, while at the same time, smoking another substance would become legal. I can see why people might be confused.
Furthermore, when cannabis is ingested in its edible form, be it as a syrup or lozenge, it is much easier to determine accurately the concentration of its two active ingredients. I would like to say a few words about these two ingredients, because they are important. These studies have yielded some interesting results.
First, cannabis contains two cannabinoids: THC and CBD, also called tetrahydrocannabinol and cannabidiol. These two substances seem to have a different effect on our body's endocannabinoid system. THC is the psychoactive ingredient, and it is believed to act on the immune system in such a way as to reduce inflammation, alleviate pain, enhance the mood, trigger euphoria, increase appetite, relax the muscles, reduce certain types of seizures and relieve nausea.
We must not forget that it is also the substance that produces euphoria.
Cannabidiol does not produce a euphoric effect. It is used much more for pain relief, reducing nausea and anxiety, controlling epilepsy, immunosuppression, and muscle relaxation. It is also an anti-psychotic, it reduces inflammation and insomnia, and it is calming.
The reason I wanted to take the time to explain this is that many studies have shown the pot available on the streets has increasingly high concentrations of THC and lower and lower concentrations of cannabidiol. That is why we are seeing more and more episodes of toxic psychosis: cannabidiol tends to neutralize the more psychotic effects that may occur.
The product on the streets has higher levels of THC, which means that it is becoming riskier.
The reason I wanted to explain this is because it would make it possible to have edible products in which all chemical substances could be carefully controlled. It would also make it possible to prevent some of the side effects that are common with the increasingly stronger strains of street drugs. One way to better control side effects and psychosis is to increase cannabidiol and reduce THC.
When it comes to dried herb products, it is really hard to control the concentration of substance in each product. What that means is that we are about to legalize a product that is much more difficult to control, but we are waiting to legislate on edible products, even though they would be much easier to control and it would be easier to limit THC and cannabidiol concentrations.
I find that a little strange. It would have made a lot more sense to legalize edibles right away, while imposing limits on the various substances, such as THC and CBD, to determine how much of each substance could go in the products.
The other reason it might be particularly useful to allow edible products and to be able to control each chemical is for the purposes of research and improving our understanding of this substance. Even though medical pot has been in use for a decade or so, the fact remains that knowledge of its effects on the human body is often based on anecdotal evidence. Essentially, this means someone started taking it on their own and found that it helped with a condition they had. Our knowledge is not based on conventional clinical research, but on personal experiences compiled over time. Since some discoveries were based on anecdotal medical evidence, the results are not 100% reliable.
It is important to bear in mind that even though we are talking about recreational use, many people still take cannabis for medical purposes. Even though they do not have a prescription, they decide to try cannabis and find that it helps with their insomnia or other health problems.
Singling out recreational use and completely ignoring those who use cannabis for self-medication is not right. We need more information so we can better educate people on the actual effects of cannabis.
One of the problems is that we currently do not have that information, and many people who might decide to take cannabis could be endangering their health, because they do not fully understand the substance or the circumstances in which it might be useful or dangerous.
This bill should have placed more emphasis on health and the prevention of side effects. I also sincerely believe that not allowing edible products, only dried herb products, is somewhat illogical.
