After trying cocaine, I found it to be the biggest waste of time/money ever. I seriously got similar effects from taking like 6 or so caffeine pills, sans the constant running nose, disgusting drip, and ruined nasal passages. The stuff is so addicting, and makes you depend on it. To feel halfway normal the next day you have to do more. My advice to coke heads- try a psychedelic drug and compare the experience to coke. You won't look back.
