It's an excellent question. Obviously you know the field. There are many components within the THC plant, and we need to study it very carefully. If you study the effects of marijuana, you will know that one strain is not the same as the other because there are different components. THC and CBD are the two active ingredients with different properties, and we don't really understand exactly the advantages and disadvantages of the different components. It would be very interesting to get studies that look at the different kinds of mixes in a known amount so that you would know what you were dealing with. If you open it up to its just being a marijuana study, the question is whether a marijuana species here would be the same as the one that you're going to get in Toronto or Vancouver, and the findings might not be transferrable. Therefore, it's very important to initially do a study in which you're looking at the actual components in a titrated way just as you would give a drug treatment, so that you would know what you're dealing with. Once you have clear answers, you can match up the strains of marijuana with the specific kind of profile that you want.
