Industrial hemp growers in New South Wales are flouting the law to produce medical cannabis products for the black market, according to the head of Australia's largest hemp seed food producer.

Purchasing this item on the black market brings risks such as the unknown contents of the CBD products,  Mr Cochrane says, "They don't know what's in it, they don't know how it's grown, they don't know if it's got mould, they don't know if it's got pesticides, heavy metals — the list just goes on,"
