Crack cocaine is a drug which has become increasingly popular in the UK in recent times. A few years ago the police described it as a "crack epidemic". Along with this, there was also a rise in the use of normal cocaine, the difference being that crack is cocaine which has been washed back and allowed to crystalize. The difference between the effects of cocaine and crack cocaine is huge! The high from smoking crack is extremely intense, so intense that the first time you try it you will probably be sick... followed by an intense euphoric high and an instant craving for more. Crack is highly highly addictive and is definitely more addictive than smoking heroin.
