Smoking itself isn’t great for health and irresponsibly throwing cigarette butts can have drastic consequences which are hard to anticipate. Some smokers don’t go forward with the effort to dispose of cigarette butts appropriately, and sewer holes seem like a great idea.
A video from Tehran shows a similar incident where a man can be seen throwing a cigarette butt in a sewer hole. Moments later the hole blows up with high intensity and the man is thrown on the ground as dust and ash cover the screen.
The video has been viewed over a million times and while the reason is unknown netizens pointed out gas leak or methane build up as possible causes.
