CBD will be placed it in the same category as heroin, cocaine, methamphetamine and more than 200 other substances deemed as "dangerous drugs," with users facing a hefty jail term.

The move is expected to wipe out businesses in the city that had, until now, been able to sell CBD-infused products including beer, coffee and health supplements.

The Dangerous Drugs Ordinance (Amendment of First Schedule) and the Control of Chemicals Ordinance (Amendment of Schedule 2) will be published today.

The two amended laws will be vetted at the Legislative Council on Wednesday. They are expected to take effect on December 16, while the control on CBD will take effect on February 1 next year.

"CBD products should be disposed of as soon as possible to avoid violating the law," a government spokesperson said.

Disposal boxes for CBD products will be arranged from Thursday to January 30 at 10 government premises across the city. After the deadline, anyone who possesses or consumes CBD faces up to seven years in jail and fines of up to HK$1 million.

CBD is one of the active ingredients of cannabis but does not have psychoactive properties.

Users touted its relaxing and pain-relieving properties, but Hong Kong's Security Bureau dismissed such claims. CBD is legal in the United States and parts of Europe, as well as in some Asian nations including Japan and Thailand.

China last year banned the use of CBD in cosmetic products.
