Do not let it get too hot-- swirl the lighter around and keep it a short distance from the spoon--- when oyu see it bubble a little bit take the lighter away, than put it back. Cocaine is about 4% average street purity, to cook with bicarb add 30% bicarb to mixture and wash this will result in a crack rock of about 2.5% purity, this is why people think crack is shit these days, two years ago an average crack rock would be at least double this.

It’s been commonly accepted that crack is more addictive than other drugs, but addictions researchers and drug counsellors say it’s hard to compare the addictiveness of specific substances because drug-taking is a highly individual experience. Is it possible to smoke crack once and walk away?

Robin Haslam, director of operations and procedures for Addiction Canada, says that he has never met someone who can “just casually smoke crack.” However, people have different thresholds of addiction. “I know people who have used crack once, and never touched it again. I also know people who smoked marijuana once, and became very impaired,” he says. Carl Hart, author of High Price: A Neuroscientist's Journey of Self-Discovery That Challenges Everything You Know About Drugs and Society, told CBC Radio’s that crack “is not uniquely addictive, or it’s not something that is special, as we have all been taught.” Hart said that the percentage of people that become addicted to crack is lower than most think.

“For example, 10 to 20 per cent of people will become addicted — that means that 80 to 90 per cent of people won’t become addicted.” • Crack emerged as a concern in the 1980s Crack is a smokeable form of cocaine that is typically prepared by condensing cocaine and baking soda into a “rock.” It first emerged in large U.S. Cities in the early 1980s. In 1986, Time magazine called crack “an inexpensive yet highly potent, highly addictive form of cocaine” that was rapidly spreading across America. This contributed to crack’s reputation as being among the most addictive drugs. Police say each packaged tablet of crack cocaine sells at about $10 on the street.
