One study found that placebos sometimes work even when the subject knows it’s a placebo. Another, using that same public speaking setup that CBD studies have used, found that anxiety treatments are particularly susceptible to the placebo effect, with 40 percent of placebo-treated patients showing a decrease in anxiety symptoms while tasked with speaking to a crowd.
If you’re taking the oil in liquid form, one dropperful of a low concentration product (100 mg CBD per fluid ounce) will provide about 3 mg of CBD per dropperful — not enough to notice any significant effects. A dropperful of the medium grade product (500 mg of CBD per fluid ounce) will deliver about 15 mg of CBD — a good starting dose. And a dropperful of a high concentration product (1500 mg CBD per fluid ounce) will provide about 50 mg of CBD per dropperful.
The mosaic of laws that govern CBD legality across the globe varies just as much as the legislation across the US. Generally, CBD extract is legal in most countries, but what makes it illegal is where and what it’s extracted from. Most Group of 20 (G20) countries allow CBD extracted from industrial hemp, but not CBD extracted from whole-plant marijuana. Note, however, the differences between the two. Legislation regarding international travel with CBD also varies among countries. For the foreseeable future, the best practice would be to search online, or contact the respective embassies or consulates, before traveling to determine whether your CBD is safe and legal.
