The worst litter of all...

...with Tim Horton's coffee cups coming in a close second.

Seriously, though. Most smokers would not even think about tossing their coffee cups or food wrappers onto the ground, but mindlessly throw their cigarette butts all over the place. CityNews just posted this story about the problem. Here's a quote from the article:

To put things in a national context, an estimated 52 million cigarettes are tossed onto Canadian streets each year. In global terms, there are those that suggest they're the world's most littered item, a claim with shocking implications given that it takes a single butt an average of 25 years to break down.

25 years! And not to mention that before the butts even break down, all the chemicals get washed into our waterways or find their way into our soil.

How about making portable ashtrays like these or these fashionable smoker accessories?
