Smoking in hospital room

Hey all. So im currently gonna be hospitalized for the next week or so and I brought my cart along. I normally just suck it up when I have to stay in the hospital (since I do pretty often) but I decided I would actually like to get some rest for once during my stay lol. In other words, I need my cart to sleep.

The bathroom doesnt have a fan/air vent so I was wondering if anyone has some ideas on how to not get caught. Can I blow the vapor down the sink and turn the water on?

Promise I dont need a lecture, I know this is a shit Idea. Cant tell my doctors I need medicinal marijuana either because they will make a fuss out of it (trust me, I know this hospital well). Any tips would help.

UPDATE: Thank you all for the replies!! I was successful in blowing it into a flushing toilet with baby hits 👍
