Hampton Sides (surely a pseudonym?) investigates the science behind marijuana’s magnificent properties, for National Geographic:
There’s nothing new about cannabis, of course. It’s been around humankind pretty much forever.
In Siberia charred seeds have been found inside burial mounds dating back to 3000 B.C. The Chinese were using cannabis as a medicine thousands of years ago. Marijuana is deeply American too—as American as George Washington, who grew hemp at Mount Vernon. For most of the country’s history, cannabis was legal, commonly found in tinctures and extracts.
Then came Reefer Madness. Marijuana, the Assassin of Youth. The Killer Weed. The Gateway Drug. For nearly 70 years the plant went into hiding, and medical research largely stopped. In 1970 the federal government made it even harder to study marijuana, classifying it as a Schedule I drug—a dangerous substance with no valid medical purpose and a high potential for abuse, in the same category as heroin. In America most people expanding knowledge about cannabis were by definition criminals.
But now, as more and more people are turning to the drug to treat ailments, the science of cannabis is experiencing a rebirth. We’re finding surprises, and possibly miracles, concealed inside this once forbidden plant. Although marijuana is still classified as a Schedule I drug, Vivek Murthy, the U.S. surgeon general, recently expressed interest in what science will learn about marijuana, noting that preliminary data show that “for certain medical conditions and symptoms” it can be “helpful.”
In 23 states and the District of Columbia cannabis is legal for some medical uses, and a majority of Americans favor legalization for recreational use. Other countries are rethinking their relationship to pot too. Uruguay has voted to legalize it. Portugal has decriminalized it. Israel, Canada, and the Netherlands have medical marijuana programs, and in recent years numerous countries have liberalized possession laws.
Ganja is simply around us more, its unmistakable but increasingly unremarkable smell hanging in the air. Yes, smoking it may lead to temporary laughing sickness, intense shoe-gazing, amnesia about what happened two seconds ago, and a ravenous yearning for Cheez Doodles. Though there’s never been a death reported from an overdose, marijuana—especially today’s stout iterations—is also a powerful and in some circumstances harmful drug.
Still, for many, cannabis has become a tonic to dull pain, aid sleep, stimulate appetite, buffer life’s thumps and shocks…
