I smoke cigarettes.Is it bad to take a multi vitamin and mineral supplement that contains 2500iu of vitamin A and beta carotine.?

"According to NYU Langone Medical Center, cigarette smokers may lack sufficient levels of the following:

Vitamin C

Vitamin E

Zinc

Calcium

Folate

Omega 3 and 6 fatty acids

Lycopene

Beta-Carotene*

*It should be noted that a large double-blind study indicated that heavy smokers who supplement with beta-carotene could increase their risk of lung cancer. For this reason, you may want to avoid such supplements until after you’ve successfully quit smoking, or look for a multivitamin with a lower dosage of beta-carotene/Vitamin A."

"Q. I’m a former smoker and have an occasional cigarette socially. You’ve warned that beta carotene increases the risk of lung cancer in smokers. My multivitamin lists “vitamin A 2,500 IU, 40% as beta carotene.” Should I stop taking it?

A. You shouldn’t worry about the beta carotene, but rather your occasional smoking.

The four large studies from the 1990s showing that beta carotene pills increase the risk of lung cancer in smokers (by about 24 percent) used doses at least 40 times higher than that in your multi. Plus, they focused on fairly heavy smokers; former smokers did not seem to be at risk. No one knows the safe dose of beta carotene for smokers. Still, your low dose and your light smoking would presumably greatly reduce the risks posed by the interaction."

Smoking while taking any type of vitamins does not work because the nicotine kill, s it wouldn't work and you would be wasting your money on them.
