Sounds somewhat similar, but not sure how oxy would help with bronchitis. Although I think they do use codeine in cough syrup as a cough suppressant. But oxy is a lot more heavy duty. I had back problems for years and had taken vicodin whenever things got bad and I couldn’t walk. The oxy felt like I had taken a whole handful of vicodin, it was lot stronger.
Since we’re on the topic, you should watch the doc OxyContin Express. It’s about when it was less regulated and people abused the shit out of it (in Florida of course). Scary stuff really, not much different than shooting heroin they way people were snorting and smoking it.
