Last year, the California Department of Correction and Rehabilitation banned all smoking in its prisons. Like narcotics, tobacco has become illegal in prisons. And, like narcotics, black-market tobacco is plentiful but expensive in prisons. For folks who want to continue their habit, they'll have to pass through the nose. The alternative is to quit.
There are many people who were able to quit their addictions of narcotics and tobacco. When there are fewer resources for access, people are forced to quit their habits. When people are able to take advantage of their confinement to overcome their addictions, it's a blessing in disguise.
