Nancy Grace ignores pro-marijuana advocate: 'Obviously you're stoned'

In America's ongoing debate about legalising marijuana, it seems HLN host Nancy Grace has come up with the perfect retort for those in favour of the drug.

Grace appears to now see herself as an expert in the topic (having spoken to rapper 2 Chainz recently) as well as a crusader against a drug she says can cause untold damage.

On Tuesday, she brought up the case from last year of a woman in Colorado being shot and allegedly killed by her husband, who was high on marijuana.

"How can you insist that pot be legalised?" she asked National Organization for the Reform of Marijuana Laws (NORML) chair Norm Kent.

"Your argument is not real because you take isolated instances of aberrant behavior and try to make them standardised for all marijuana users," Kent said. "And once and for all, Nancy, have you no conscience? When will this stop?"

"I was really just looking for an answer to the question, but obviously you're stoned," Grace replied.

Grace is a former special prosecutor in Georgia and debated the issue of marijuana legislation with 2 Chainz a few weeks ago.

Once again, before she began the conversation, she brought up the story of a death allegedly contributed to by the use of marijuana: a three-year-old girl who died in a house fire while he parents were allegedly drinking and smoking the drug.

"From the story I just heard you talk about, they had alcohol included, which we all know causes you to black out, forget things," he said. "They also dealt with irresponsible people. I don't think you could put an umbrella on the whole community off these few incidents that you just named."

It is now over a year since Colorado became the first state in the United States to legalise marijuana. Since then, Washington, Alaska and Oregon have voted in favour of similar legalisation. Votes in Washington, D.C. also voted in favour in November, with the legislation now under review in Congress.

Cannabis remains a Class B drug in the UK, carrying a prison sentence for possession of up to five years.
