Here’s some “stoner superstitions” from Leafly. I’ve never heard of the “white lighter” one:
Smoking cannabis with one carries extremely negative vibes. The bad juju can lead to broken bongs, getting busted, or even having your grow ruined by weather. Avoid using a white lighter to smoke cannabis at all costs or suffer certain catastrophe.
When I was in high school, people said that some color lighter meant you were gay. I don’t remember which color (maybe red?). Anyway, this just seems like fleeting rumor, not a real superstition. But we shall see whether people are still talking about it in a few years.
Also, the idea that you should punch people who cough on a hit is stupid. Aside from being mean and needlessly violent, coughing is a good thing; it gets you higher. No one should be punished for that.
