    Spice is an herb that is supposed to be used for incense. It can be bought in smoke shops, or at least it used to be possible to buy it in smoke shops. But at some point, people started trying to smoke it to get high. It has marijuana-type properties, plus there are other things in it. The Food and Drug Administration (FDA) has been trying to figure out what's in it and how it works.

    It does contain psychoactive substances that cause people to have fairly severe hallucinations. The people I have seen who have smoked spice claim it's not a pleasant experience. They vomit and feel uncomfortable. And all of them, without exception, have said they’ll never do it again, because it was so unpleasant.

    Pack years for smokers are the number of packs smoked per day multiplied by the number of years a person has been smoking. For example, if someone has been smoking 2 packs of cigarettes per day for 40 years, that would be equal to 2 x 40 = 80 pack-years. The more pack years, the higher the risk of complications for a smoker such as heart disease, chronic obstructive pulmonary disease, and lung disease.

    E-cigarettes are relatively new, and not very much is known about how harmful they are to your heart. E-cigarettes are often advertised as a safer alternative to regular cigarettes.  E-cigarettes are currently not regulated, and therefore, we do not know what chemicals or toxins may be present. Due to this, many medical societies recommend caution with use of e-cigarettes until more is known about their safety.

    Although effective new strategies have increased the success rates among people attempting to quit, those rates are still only about 20 percent. But a relapse shouldn’t be seen as a sign that trying to quit is futile. “If you’ve tried before, statistics show you actually have a better chance of being successful,” UCLA internist Mark S. McGowan, M.D., says.
