Although many states have legalized the use of medical Marijuana, they have also adopted regulations to control the use of the drug. For example, in 2003 California passed Senate Bill 420,which imposes limits on the amount of Marijuana patients are allowed to posses and grow. The bill also protects the state's dispensaries , or designated stores that sell medical Marijuana, from criminal sanctions.
As more and more states legalized the use of medical Marijuana, the industry began to rapidly expand. Hundreds of dispensaries began opening in the States that legalized the drug. By 2011 more than 1,500 dispensaries and growing operations were being run in the country, and nearly twenty-five million Americans were permitted to use medical Marijuana.
Opponents of medical marijuana argue that it is too dangerous to use, lacks FDA-approval, and that various legal drugs make marijuana use unnecessary. They say marijuana is addictive, leads to harder drug use, interferes with fertility, impairs driving ability, and injures the lungs, immune system, and brain. They say that medical marijuana is a front for drug legalization and recreational use.
Proponents of medical marijuana argue that it can be a safe and effective treatment for the symptoms of cancer, AIDS, multiple sclerosis, pain, glaucoma, epilepsy, and other conditions. They cite dozens of peer-reviewed studies, prominent medical organizations, major government reports, and the use of marijuana as medicine throughout world history.
