Dr. McCara states, "If legalised, snus might be taken up by people, especially the young, who might never have smoked tobacco but who may then progress to doing so."
Let us examine two questions concerning the risk: 1. Is this fear justified? 2. If so, can anything be done to mitigate the risk?
The National Survey on Drug Use and Health (NSDUH) Report (sponsored by the Substance Abuse and Mental Health Services Administration, an agency of the U.S. Public Health Service) March 5, 2009: Smokeless Tobacco Use, Initiation, and Relationship to Cigarette Smoking: 2002 to 2007, states that 65.5% of smokeless tobacco users started using cigarettes first.
Therefore, many more Americans are reducing their risk by switching to smokeless than are increasing their risks by switching to smoking.
Now let's examine why, according to the NSDUH report, 31.8% did progress to smoking.
Only 15% of the U.S. population realizes that smoking presents vastly greater health risks than using smokeless tobacco. One of the required warning labels on smokeless products is "This product is not a safe substitute for smoking." Obviously, the majority of people have interepreted this message "smokeless tobacco is no safer than smoking."
Given the message that "you might as well smoke," many people did just that.
If Americans had been provided with complete, accurate information, it is probable that very few would have progressed to the more dangerous form of tobacco use.
So providing accurate information to everyone is one way of mitigating the risk. Other ways of mitigating the risks to the young non- tobacco user is to step up programs aimed at tobacco prevention, and to call upon parents to do their part to protect their children.
This same fear-for-the-children is being used as justification to ban another harm-reduction tool that might prove to be even safer than snus, since it contains no tobacco: the electronic cigarette.
Finally, let us examine a different risk, not mentioned in Dr. McCara's article: If harm reduction products are not made available, they will not be taken up by people who are unable to quit smoking. Millions will sicken and die horrible, painful deaths.
