Important advice for first timers:

1. Big lines. No wider then your nostril though.
2. As soon as you feel it wearing off, you have to do more.
3. Feed this urge continuously until your wallet is empty.
4. Fatter lines. Bigger then your nostril is now okay because half of it flies out the hole in your nostril anyway.
5. More lines. More often. This step is important.
6. Go through a full week without being able to do coke.
7. Vow to never touch coke again.
*8. Repeat.

Steps with an asterisk * are optional.
