Why does smoking make you lose weight?

The metabolic effect of smoking could explain the lower body weight found in smokers.

Does nicotine affect Xanax?
Lately, misuse of prescription benzodiazepines (such as alprazolam or Xanax, and diazepam or Valium) has also been linked to nicotine use. These connections have all been statistically derived — researchers did not directly study human interaction with these drugs.
