Legislatures across the country are legalizing medical marijuana, but the nation's physicians aren't requesting these laws. The American Academy of Pediatrics and the American Society of Addiction Medicine are both against medical marijuana laws. The American Medical Association doesn't support them either.

Groups representing patients aren't behind these laws. The American Cancer Society hasn't demanded them, and the Glaucoma Foundation even warns patients against using the drug.

Instead, the demand comes from groups like the Drug Policy Alliance and Marijuana Policy Project. These are not medical organizations. They are part of a pro-legalization lobby supported by pro-marijuana billionaires. And they've apparently convinced state legislators to ignore some very serious problems.

The biggest problem is that medical marijuana laws are responsible for most of the growth in adolescent use. According to the University of Michigan's Monitoring the Future survey, teen use in the U.S. surged between 2005 and 2011. But it didn't surge equally in all states.

Data from the National Survey on Drug Use and Health show that the number of teens who smoked pot over the past month increased by 33 percent in medical marijuana states, but by only 6 percent in the rest of the country. In 2005, only about 20 percent of the U.S. population lived in medical marijuana states, yet those states accounted for more than two-thirds of the increase in adolescent use between 2005 and 2011. If it weren't for states with medical marijuana laws, teen use would have barely increased at all.

There's also evidence that even among adults, nearly all of the "medical" marijuana goes to drug abuse. The largest survey of medical marijuana patients, published in 2014 in the Journal of Global Drug Policy and Practice, found that only 6 percent reported using marijuana for cancer, AIDS, glaucoma, Alzheimer's, Crohn's, hepatitis C, or amyotrophic lateral sclerosis, also known as Lou Gehrig's disease. The vast majority — 91 percent — got their marijuana for pain.

Research shows that most chronic pain patients are women. In 2001, the journal Pain published a study by researchers who interviewed more than 17,000 people and found that 54 percent of those with chronic pain were female. On the other hand, five years of data from the NSDUH showed that adult marijuana abusers were 69 percent male. So if the pain patients using medical marijuana are genuine, they should be mostly female. If they're substance abusers faking or exaggerating pain just to get high, they should be about 69 percent male.

Between 2011 and 2013, I contacted all of the state medical marijuana programs and got data from seven. In all but one of the states, 64 to 74 percent of the pain patients were male.

These numbers are nowhere near what we would expect from a cross-section of legitimate pain patients. Instead, they're clustered around the result we would see if the patients were all substance abusers. So while not every medical marijuana patient is misusing the law just to get high, the great majority probably are.

A 2011 study from the Journal of Drug Policy Analysis found similar results. The researchers surveyed 1,655 consecutive patients from nine medical marijuana clinics in California and found that the average patient was a 32-year-old man who started smoking pot as a teenager.

Not only are these laws harmful, but they're completely unnecessary. While some seriously ill patients are helped by marijuana, there are four prescription cannabinoid medications that are just as helpful. So there's no reason to use marijuana itself as medicine.

Two of these medicines, Marinol and Cesamet, are available in the U.S. by prescription. A third, Epidiolex, or pure cannabidiol, is available for children with seizures through a special Food and Drug Administration program. The fourth, Sativex, is in the last stages of approval.

Some of these medicines have fewer side effects than marijuana and are longer-acting, which means they are better for genuine patients who don't want to be stoned all the time. However, the biggest advantage of prescription cannabinoids is that they're much less likely to be abused or diverted to teenage use than medical marijuana is.

Legislators should ignore the pro-marijuana lobbyists and instead listen to the American Medical Association, the American Academy of Pediatrics and the American Society of Addiction Medicine. If we want to rein in teenage marijuana use and prevent widespread abuse of the drug, instead of passing new state medical marijuana laws, we should get rid of the ones we already have.
