I've smoked mainly bongs most days for a few years, and my lungs are starting to feel it. Back in the day the dumb hicks I went to high school with smoked poppers, which is basically a water bottle with some water and a (preferably glass or metal) tube as a stem through the side. Simple makeshift plastic bong. Then they'd rip off entire chunks of cigarettes, I saw one kid do an entire cig once, and shove it in the tube. Then they pack a little kush on top and light it up, eventually sucking the cig into the water and inhaling.
It was the dirtiest dirt **** I've ever seen, and I still tried it a few times. Overdoing that filterless plastic cancer smoke feels like heroin withdrawal lmao. Long story short, I think I perma-****ed my lungs. I'd be willing to look into a vape if anyone has good recommendations.
