Properly the most over priced and over rated drug I've ever come across, you don't want to be rocking it up and smoking crack not only is it high;y addictive and the high lasts but a few minutes its really rough on you lungs.
An amphetamine than you can just do orally would give you a much better high at a fraction of the cost, I understand it won't it quite the same as coke so in many ways its not really helping you much in your quest.
I'd have to say the snorting, IME is the best ROA for coke HCL....although has any tried plugging it, it is very water soluble ? can't see why that should work quite well
