Can you ban what you don’t notice?

Effectively, that is, not legally. A technological blow for freedom in the drug wars:

More and more, people are smoking marijuana out of e-cigarettes and vapor pens — right out in the open with little or no fear of getting caught, users and experts say.

“I was on the train from New York to Baltimore and I enjoyed the pen the whole way there and back with no one noticing,” said one life-long marijuana user who asked not to be identified. “I absolutely was thinking ‘This is not bad at all.'”

As Spacebunny commented, the only surprise is that it took pot smokers so long to figure it out. I don’t partake of the herb myself, but I am 100 percent pro-legalization.
