These days, CBD - cannabidiol, a chemical derived from cannabis - has been getting a lot of buzz.
But don't expect it to give you an actual buzz.
Countless products containing CBD have cropped up in recent years, touted as natural remedies for ailments ranging from joint pain and seizures to anxiety and insomnia.
"It has a fad appeal," says Robert C. Speth, Ph.D., a professor of pharmaceutical sciences at Nova Southeastern University in Fort Lauderdale. "Everyone is talking about it. It's the supplement du jour."
Because CBD is non-psychoactive and contains no THC, it doesn't produce the high associated with marijuana. That means it's legal in Florida, making it enticing to those who want relief minus mind-altering effects.
"CBD as a therapeutic agent appeals to people of all ages," says Dr. Speth.
You'll find CBD sold in various strengths and forms - including oils, capsules, edibles and topicals - at health food stores, smoke shops, pharmacies and more. People might dab CBD lotion on problematic areas or drizzle CBD oil into their morning coffee. Recently, The Chocolate Spectrum Café and Academy in Jupiter even launched a line of CBD chocolates.
CBD is found in both hemp and marijuana plants. But, because Florida hasn't legalized recreational marijuana, CBD products sold statewide are derived solely from hemp, which is legal. You need a medical marijuana card to buy CBD products derived from marijuana in Florida.
Still, CBD is typically safe and well tolerated. It may cause side effects like sleepiness, diarrhea, rash, decreased appetite and weakness, and it may interact with some medications, like antidepressants. Consult with your doctor before trying it.
"CBD is a drug. Like all drugs, its effects can vary with the dose," says Dr. Speth. "In general, higher doses of drugs will lead to more unanticipated side effects."
