The marijuana plant has chemicals that can help with some health problems. More states are making it legal to use the plant as medicine for certain illnesses. But there isn’t enough research to show that the whole plant works to treat or cure these conditions. Also, the U.S. government still doesn't think of marijuana as medicine, so it's still illegal at the national level.
A few medicines have been made as pills and oils. These medicines have chemicals that are like the ones in the marijuana plant, but are not the same type that people usually smoke. They can:
- treat nausea if you have cancer
- make you hungry if you have AIDS and don’t feel like eating
Smoking medical marijuana can also hurt your lungs. These and other effects on the brain and body could make marijuana medicine more harmful than helpful.
Another problem with marijuana as a medicine is that the ingredients aren't exactly the same from plant to plant. There's no way to know what you're getting.
Scientists are trying to find ways to make safe medicines from marijuana.
