But just like cough syrup .... All the 'good' stuff (1,1,1-Trichloriethane) has been taken out of it. In this case it was the solvent which made it so good at gently cleaning a surface. Knuckleheads were probably 'sniffing' it for a high as they will do with many things. I have half a tiny bottle left which I use for 'special' cases.
