在加州，大麻成份中的大麻二酚（Cannabidiol，簡稱CBD），被指副作用較輕，而且監管寬鬆，被生產商大舉吹捧，以糖果、蛋糕、按摩油、護膚品等姿態流入市面，捲起一股「CBD」熱潮。但州政府指，食品內含有「CBD」成份屬違法，且安全成疑，更有地方政府採取行動，警告起訴出售食物內含有「CBD」的餐廳。
加州衛生局7月份發出公告，強調政府立場對其安全存疑：「在另行通知前，漢麻油（Hemp Oil）或大麻二酚製品（CBD），均未被加州認證對人類和動物安全，不是被批准的食物成分、添加劑或膳食補充劑。」局方補充，服用「CBD」會導致嗜睡，食慾減退，腹瀉，疲勞等問題。在加州相對保守的地區橘郡（Orange County），郡政府日前採取行動，扣留生產含有「CBD」成份咖啡的Coffee Dose存貨，警告負責人若繼續出售該產品，將面臨民事檢控。
大麻二酚（CBD）和四氫大麻酚（THC），為大麻內兩大主要成份，目前在多個州份已合法化的大麻葉（marijuana），含高濃度精神活性成分「THC」，是服用者「致嗨」主因，且容易成癮。不過，同屬大麻類的漢麻（Hemp）（指大麻根、莖），則含有「高CBD、低THC」比例，在提取「CBD」時候，被認為成癮性較低，甚至有助抗焦慮和思緒紊亂等藥效。
今年6月，美國食品藥物管理局（FDA）破天荒承認一款含有「CBD」成效的口服藥物「Epidiolex」，該藥用以治療兩種嚴重兒童癲癇症。這款第一次獲FDA批准的大麻處方藥，由英國藥廠GW Pharmaceuticals生產，一年藥費約3.2萬美元，不含使人興奮的「THC」效果。就此，當局正考慮把與大麻和海洛英並列為一級管制毒品的「CBD」，放寬下調至第二級至第五級藥物。
連結：FAQ – Industrial Hemp and Cannabidiol (CBD) in Food Products（California Department of Public Health，CDPH 美國加州公共健康部公告）
California Department of Public Health (CDPH), Food and Drug Branch (FDB) has received numerous inquiries from food processors and retailers who are interested in using industrial hemp-derived cannabidiol (CBD) oil or CBD products in food since the legalization of medicinal and adult-use marijuana (cannabis) in California.
In California, the CDPH Manufactured Cannabis Safety Branch (MCSB) regulates medicinal and adultuse manufactured cannabis products. However, food products derived from industrial hemp are not covered by MCSB regulations. Instead, these products fall under the jurisdiction of CDPH-FDB.
California defines “food” as follows:
(a) Any article used or intended for use for food, drink, confection, condiment, or chewing gum by man or other animal.
(b) Any article used or intended for use as a component of any article designated in subdivision (a).1
The definition of food includes pet food, but does not include products containing cannabis (which are, instead, cannabis edibles). Meat, dairy, poultry or eggs are regulated by the California Department of Food and Agriculture (CDFA).
The federal Agricultural Act of 2014, also known as the Farm Bill, only legalized the growing or cultivating of industrial hemp by state departments of agriculture and institutions of higher education (as defined in Title 20 of the United States Code section 1001) for purposes of research under a state pilot program or other agricultural or academic research.
In addition, growing or cultivation is only permitted under the Farm Bill if growing or cultivating is allowed under the laws of the State in which such state department or institution is located and such research occurs. In California, the cultivation of industrial hemp is regulated by the CDFA.
