The growth in the trade in cigarettes via the internet is also supported by Cohen and Sarabia, et al. (2001). Cohen and Sarabia, et al. (2001) point out that, in the view of the tobacco industry, internet is a marketplace that they cannot miss. Especially, they believe that it is very difficult for any individual nation to launch regulated policy to control this area successfully. Furthermore, Tobaccofreekids (2005) also shows that, during 2000 to 2002, the number of people who purchased cigarettes via the internet had risen from 1.1 percent to 6.7 percent. This is also similar to the study of Goolsbee and Slemrod (2004) which argued that the internet increases the opportunity for smokers to buy cigarettes.
