What is medical marijuana and is it legal?
Medical marijuana is the use of this drug to help treat symptoms like pain, nausea, vomiting, and lack of appetite. It's often used by people with cancer, AIDS, multiple sclerosis, epilepsy, and other conditions.
It's against federal law to possess, sell, give away, or grow marijuana for any purpose. It's also against federal law for doctors to prescribe this drug. But more than a dozen states have passed state laws that allow people with certain health problems to buy or grow a limited amount of marijuana for their own use. Some states also allow or license people to provide medical marijuana to those who need it.
If you use medical marijuana to treat approved medical conditions, the federal government might not prosecute you. But there's no guarantee that they won't.
Medical marijuana laws are different from state to state. If you think you might want to try medical marijuana, talk to your doctor. You can also call your state department of health or health services to learn more about the laws in your state.

Are there alternatives to medical marijuana?
Nabilone is used to relieve nausea and vomiting caused by cancer chemotherapy. Dronabinol can relieve this kind of nausea and vomiting too. It may also improve the appetite of people who have AIDS. Both drugs come in pill form.

Is synthetic marijuana safe?
Synthetic marijuana, or synthetic cannabinoids, are sold as substances having effects like those of marijuana. These drugs, sold in the form of bath salts or incense, are made in labs and have many names, such as K2 or Spice. Even though they are labeled "not for human consumption," people are more likely to try them since they are easily bought in stores and online and can't be detected by drug screenings. Also, people think they will feel the same as when they use marijuana. But these drugs are stronger than marijuana, and they are not safer than marijuana.
