Actress Whoopi Goldberg has launched her own line of medical marijuana products to treat period pains.

The product will solely be on sale to those with medical permission to take the drug.

The Hollywood star said"For me, I feel like if you don't want to get high, this is specifically to get rid of discomfort."Smoking a joint is fine, but most people can't smoke a joint and go to work."

She added: "You can put the rub on your lower stomach and lower back at work, and then when you get home you can get in the tub for a soak or make tea, and it allows you to continue to work throughout the day."

Whoopi, 60, is not the first high-profile figure to launch business ventures related to marijuana.

Rapper Snoop Dogg launched 'Leafs by Snoop', his own brand of marijuana, in November 2015, after the drug was decriminalised in a number of states.
