Thank you fredrik29. You don't smoke powdered cocaine. If you did, you would be inhaling all of the cut the dealer put in it, plus the chemicals used to process the Coke. I did enough of this stuff as a 20 something kid to fill a tanker. Cocaine is processed with Hydro-Chloric Acid. Liquefying the base product yields a yellowish rock substance. This on the street is known as 'Crack'.
Smoking cocaine, or freebasing, as it was known then is nothing that a coke-head would waste rolling into tobacco. One time and you never want to put it down. The euphoria felt while under the influence of base cocaine is something you never want to start. That's why crackheads will kill, rob and do whatever it takes to get their next rock.
