Alright, you're probably familiar with the things. And, you can probably agree that the people using them have quit smoking-on a technicality. As there's nothing actually burning, it's true that no smoke is produced. However, many of these people still crave nicotine. This craving is satisfied by filters and vaporizing solutions of varying concentration, from 0 up to 36 mg of the stimulant. Is it hard to stop a nicotine habit when you're hooked? Of course. It's been likened to quitting heroine or crack. Nicotine is far more deadly than either of those things, though. Let's look at the average dose capable of killing at least 50% of those who take it regarding the three substances; Crack= 1.2 grams Heroine= 200-500 milligrams Nicotine= 30-60 milligrams Because tobacco is still such a huge part of modern culture, people don't really know how deadly nicotine can be; though that's not why this thread was made.
