As far as the comedown goes, it's not very enjoyable like weed, or how ecstasy was alright my first (and only) time. The effects of coke last about 45 minutes or so for a good sized line, and good quality coke. As soon as you start coming down, I experienced an intense craving to snort some more, which lasted for an hour or so. After this duration I felt alright, but maybe a little bit bummed out...as if I just stubbed my toe as I dropped a brand new hamburger onto the ground. There isn't a physical element to the comedown, just a strong psychological desire to take some more. Would I recommend trying coke? Yes, and no. Buy a gram and make sure you use it all up that night, don't use a little 'every now and then' or else there's a chance that it may develop into a habit. If you have any kind of heart problems then don't do it either, because your going to have a shitload of energy and your heart rate is going to rise. As long as you have a strong sense (at least 7 out of 10) of self control, then experimenting with coke is a great idea in my opinion, it's a completely fantastic drug when you don't let it become a habit.

While powder cocaine can be smoked to some effect (despite common belief otherwise), it is a very inefficient method of ingestion. Because of the high temperatures present when smoking, powder cocaine tends to burn rather than vaporizing. For this reason, freebase cocaine, also known as crack, is created from powder cocaine for smoking. Freebase cocaine vaporizes at smoking temperatures providing more effect with less material, as well as faster onset and a more intense high than powder cocaine..
Effects--- Alot like speed, but "cleaner" and not as long-lasting. Basically it gives a person lots of energy, makes them more alert and more sharp mentally, gives people a "euphoria" thats difficult to explain--- it's sort of a feeling of invincibility with a simultaneous feeling that all is right in the world. Some people say that it's like ecstasy but you love yourself instead of others. Cocaine also has a pleasurable numbing effect (on gums, lips, etc).
Unfortunately, the drug only lasts ~40 min at the most and the crash is very, very bad, with intense cravings, depression, and paranoia. Addiction soon after experimental use is not uncommon.
Basically--- stay away from the devil's dandruff.
