Experts also stress that recent regulation will resolve many of the historic problems.
Under the terms of the most commonly issued “low THC industrial hemp licence” farmers are only allowed to harvest the stems and seeds of the hemp plant (a type of cannabis).
In a 15-acre field he might expect to make around £12,000 profit from hemp products. But if he was allowed to cultivate CBD it would rise to nearly £100,000.

“I wish it would come from a UK supplier,” he said, adding that it would “lower the CO2 emissions, (with) the distance, the cost, including paperwork etc”. It would also “bring jobs to the UK”, and enable standards to be set here, he said.

Some CBD products may contain unwanted surprises. Forensic toxicologists at Virginia Commonwealth University examined nine e-liquids advertised as being 100 percent natural CBD extracts. They found one with dextromethorphan, or DXM, used in over-the counter cough medications and considered addictive when abused; and four with a synthetic cannabinoid, sometimes called Spice, that can cause anxiety, psychosis, tachycardia and death, according to a study last year in Forensic Science International.
A recent chart review of 72 psychiatric patients treated with CBD found that anxiety improved, but not sleep. “Over all, we did not find that it panned out as a useful treatment for sleep,” said Dr. Scott Shannon, assistant clinical professor of psychiatry at the University of Colorado, Denver and the lead author of the review in The Permanente Journal.
