And then as it's absorbed, it goes through the liver, which the purpose of the liver is to detoxify drugs and get them ready to be eliminated. So by inhaling these drugs, you're able to bypass some of those other processes. And again, it's a very effective way to deliver substances, especially something that has been cut into the heroin that you're taking right to the brain.

And if it already has a possibility to cross the blood-brain barrier, or is known to cause problems, neurotoxic-type problems, it can promote those.

There could have been something, that he didn't realize, because he was high, that mimicked TL early. And then maybe that dose and whatever it was in it or not in it kind of just pushed him over the edge. So it is kind of impossible to be able to tell. The other thing to remember is that humans as a whole have a very diverse way of responding to odors and tastes.

Some people are super tasters, super smellers. Some people are not. The older you get, the less you're generally able to have functioning neurons in your nose that help facilitate the detection of odors. So it really depends on a lot of factors.

The route of exposure can be really important. Several years ago, there was a popcorn factory in Texas, and this popcorn factory made those microwave popcorn bags. And so they made all different kinds of popcorn. And one of the kinds was the theater butter type popcorn. You know, everything's going fine. The public loves this popcorn.

But as it turns out, some of the lab workers started to get sick with lung related diseases. And what was happening is that these lab workers, they were in quality control. So they go down to the line and they'd have to pick maybe 15 or 20 bags off of the line, take them back to the lab, make microwave popcorn, open them up.

pour them out and count how many unpopped kernels there was because there's a standard in the industry that says you know for good quality if your popcorn pops and you only get two kernels bad batch these workers when they would open the bag there would be a puff of the butter flavor and as it turns out that substance diacetyl was severely damaging their lungs

to the point where some of them needed lung transplants and resulting in permanent damage. So this idea that, hey, wait, diacetal is generally recognized as safe for its use as a butter flavor. Yes, if you eat it. But these lab workers were being exposed to really high levels and inhaling diacetyl right into their lungs. So why is this important in today's society?

Well, there's an awful lot of vaping materials that smell like bubble gum. Or maybe they smell like buttered popcorn or mint or whatever cotton candy you want it to smell like. And they say, oh, I can put these substances in there because, look, they're safe. You know, I can eat them in my cotton candy. I can put them on my popcorn.

But when you deliver them by an alternate route, that's when you have to be really careful. There are some common substances that become lethal even in small amounts. And a good example is the substance visine. Visine is an eyedrop that you put when your eyes are really red and it causes blood vessel constriction.
