these people don't really know what lean is, so let me help you out OP.
Lean is cough syrup ( promethazine + codeine, and the brand is usually actavis) + sprite (hence the name dirty sprite) + jolly ranchers ( giving it it's OG look)
lean will definetly get you high, but that high isn't for everyone. Some people like booze, others like kush, and some people like a mixture of both. I say do whatever tf you want as long as you stay off the hard drugs.
