I think there’s a missed chance to have mint and other “cooling” herbs on the outer rim

To paraphrase Zizek: “You can’t change people, but you can change the system, so that people aren’t pished to do certain things.”

In general, people have historically always acted within a historical-material framework that influenced their actions and thoughts. Only changing the framework changes people’s actions down the line.

The thought, that it all depends on people being “better” is part of an ideological distortion, in service of the status quo. As is the thought, that you would have to change the people instead of the dynamics of production and property. Ideology presents the former as hope and the latter as impossible, when it is precisely the other way around.

Usually, I would squat down, press it against the concrete to put it out, then wait for a few seconds to make sure it’s not glimmering any more, then put it in my back pants pocket.

EDIT: And to give an actual answer - thankfully, it never happened, but I guess there is a very small but technically non-zero risk :D

When I was still smoking, I always forgot my little portable ashtray, so I did this a lot. My pants were abysmally smelly - but I can’t stand cigarette littering.
