How do people people continually snort drugs without filling their lungs?

Question

I have always wondered, to those that snort drugs (cocaine, tobacco, ketamine, whatever else) how do they keep doing it without it building up in the lungs?

Does it just keep building up in the lungs until you can’t breathe anymore? Do the lungs just fill up with powder? If so, wouldn’t you only be able to use the drug so many times before you literally suffocate?

Thanks to you all in advance, really baffled on this one 🙂

Answer 1

Same way your lungs don’t fill up with any random dust and phlegm. The mucus membranes that cover the inside of of your bronchi are covered with cilia, hairlike projections that constantly waft back and forth and push all the gunk uphill for you to either swallow or spit out.
