Man I’ll just say this....
If with all the positive things going on H town, people choose to use lean as a cultural staple, then you get what you deserve
I look at it as more of a cultural aesthetic, cuz I never sipped(know plenty who do or did including in my fam, tho) and wouldn't advise anyone to do it.
The color purple, double cuppin, jolly ranchers, sprite, thick syrup etc etc. help make up the overall vibe when you think of the urban culture in the city.
It's like the gang culture in cities like Chicago and LA. They are overall a negative influence, but are a cultural fabric. So you gotta come to a compromise on their place in those cities, cuz you can't just erase it.
