Pot's health effects
Since 1970, marijuana has been classified by the federal government as a Schedule I controlled substance, meaning it has no recognized medical uses and a high potential for abuse, placing it in the same category as heroin and LSD.
Many medical authorities, including the American Medical Association and the National Association for Public Health Policy, scoff at pot's Schedule I designation. So do legions of people who openly buy the drug at pot dispensaries in the dozens of states and countries that allow medical use of marijuana.
