12. CBD has been tested in open and placebo-controlled trials. Wide doses of up to 1500 mg/day showed no major changes to vitals, mood or central nervous system.
13. Industrial hemp is sourced from the cannabis sativa plant and is classified by law as containing less than 0.3 percent of THC.
14. Marijuana contains 0.3 percent or more of THC.
