A policeman who passed cannabis oil to Scotland for his son epileptic is the subject of a police investigation

A former policewoman who smuggled cannabis oil in Scotland for her son's epileptic is currently under investigation by police.

38-year-old Lisa Quarrell is taking the Bedrolite-based Netherlands to treat crippling seizures of six-year-old Cole since March.

The Scottish police said last night that she might be forced to explain her actions to police officers after her story was featured in a BBC documentary on Wednesday.

A spokeswoman added: "No complaints have been made about this.

"However, we are currently examining the circumstances surrounding this situation after the media coverage to badess crime."

Cannabis oil for medical purposes contains less than 1% of THC – the psychoactive that gives the feeling of being "high".

But Lisa can not have it prescribed to Cole by the NHS Scotland.

She spent thousands of pounds on flights to and from the Netherlands to buy Bedrolite, which costs £ 160 a bottle. In the BBC documentary, Lisa talked about breaking the law.

The mother, from East Kilbride, said, "I just crossed the airport and saw police officers with whom I worked.

"All the while, I know I'm about to recover my luggage containing illegal drugs."

Lisa was a police officer for 10 years before leaving the police when Cole was a baby.

The schoolboy can suffer up to 16 paralyzing seizures a day.

Lisa added: "He convulses, he slams his mouth, his eyes roll back, he falls to the ground without notice."

"It's the most heartbreaking thing to watch."

Lisa raised funds and went to the Netherlands with Karen Gray, 44, from Edinburgh.

Karen has also brought Bedrolite back to her six year old son Murray, who is suffering from severe epilepsy.

Like Cole, Murray can have up to 12 seizures a day.

The Edinburgh Police Division has not yet clarified whether an investigation would also open on Karen. Tracey Gillies, Medical Director of the NHS Lothian, said: "The hospital must take steps to ensure that the child is kept as safe as possible and to discuss it with others who have a relevant interest to protect children. "

According to the Home Office, it is illegal to bring Bedrolite into the country without an import license.

Last week, Cole received a private prescription for the drug at the Portland Portland Hospital.
