So if the reason for your termination is not illegal under the laws of your state, then yes, your employer can fire you for what you do on your own time, outside of work. A new trend is increasingly taking hold, where companies looking to reduce their health care costs have established not just a "no smoking" policy, but a "no smokers" policy.
These companies not only refuse to hire smokers, but some are even taking the drastic step of terminating current employees who smoke.
Can I be fired for smoking on the evenings and weekends, even if I have never violated their policy at work? Can my employer restrict me from working for someone else when it doesn't interfere with my work? My company has a policy which requires employees to report to the company if they're dating co-workers. This means the employer has the right to terminate your employment at any time, for any reason, for no reason at all, or for a bad reason, so long as the reason is not illegal--even if your performance has been outstanding.
In some states, if you write about political matters, you may have protection under laws that make it illegal to discriminate against you for engaging in political activity.
A handful of states have laws restricting an employer's ability to fire you for "lawful conduct outside of work," which might offer some protection.
If you value your job and truly want to quit smoking, you may want to take advantage of these additional incentives, or you may want to look for a new job without such restrictive policies.

Also, you should never conduct any business related to your second job while working for the first employer, which includes phone calls, e-mails, and use of your primary employer's supplies or business contacts.
Some companies concerned about sexual harassment have instituted strict "anti-nepotism" or dating policies which seek to prevent workers from dating certain or all coworkers.
This issue can sometimes fall into a gray area, but the answer is probably yes, your employer can restrict you from moonlighting, whether through its personnel policy or by requiring that you sign a non-compete agreement that limits the type of work you can do for anyone other than your current employer.
Most states do not have laws protecting your right to work for another employer, and in the absence of any legal protection, you are most likely employed at will, meaning you can be terminated at any time for any reason.
Generally, an employer can fire you for having a personal website or blog that it deems inappropriate, with very limited exceptions.
