I'm going to make a very short comment on that.
The potential toxicity, acute toxicity, of nicotine versus the toxicity of propylene glycol is completely different. What we're concerned about right now is the nicotine sulphate.
I'm not saying that it's impossible for young people, teenagers or young adults, to find creative ways of misusing the propylene glycol. Believe me, this is something that I deal with on a daily basis. They always seem to find a new way to get into trouble. However, if you compare the two, I mean, clearly the danger here is nicotine sulphate.
