I can understand it.

Drug addiction means the craving overtakes all other concerns. This is why less available drugs such as crack lead to the addicts resorting to crime to feed their habit.

Cigarettes are more available, that's all. The selfishness that comes from feeding your habit is there to be seen. Have a look at the awful website Forest, funded by the global drug pushers such as BAT, that lobbies to overturn public health measures in the interest of perpetuating addiction and lining the pockets of shareholders.

I too was rather shocked to hear Mike's experience.
