Charlotte Caldwell attempted to bring in medicinal cannabis oil to the United Kingdom for her 12-year-old son Billy but it was confiscated at Heathrow airport on Monday after a flight from Canada.
He said: "I genuinely don't understand why we see. medicinal cannabis through the prism of the 1971 Misuse of Drugs legislation, when actually this is a medical issue, it's not a prohibition of drugs issue, and that's what's got to change".
On Saturday after a very public week-long struggle, Home Secretary Sajid Javid used "an exceptional power" to grant treatment for the young boy, using one of the bottles of cannabis oil confiscated by airport officials.
"We have been in close contact with Billy's medical team overnight and my decision is based on the advice of senior clinicians who have made clear this is a medical emergency".
Speaking after the Home Secretary revealed he had granted a licence for Billy, she said: "History has been made today".
"I truly believe that somewhere in the Home Office there's someone with a heart and I truly believe that Billy was pulling on their heart strings", she said.
Iran beat Morocco with 95th-minute own goal
Morocco will next take on Portugal on June 20 before ending their group fixtures against 2010 champions Spain on June 25. Portuguese Queiroz takes Iran to Kazan to face Spain next time out and admits a different approach is required.
Billy's oil contains a small amount of THC, the psychoactive compound in cannabis which is banned in the United Kingdom, but taking an entire bottle's 100 doses would not create any kind of psychedelic effect, so low is the concentration.
Authorities seized it from Charlotte Caldwell, the boy's mother, when she tried to bring it into the country on Monday.
Ms Caldwell credits the oil with keeping her son's seizures at bay, saying he was seizure-free for more than 300 days while using it, but it contains tetrahydrocannabinol (THC), which is restricted in the UK.
Billy, who is also autistic, with pronounced communication difficulties, has suffered a "sudden increase in frequency and intensity of seizures" since the medication was confiscated at Heathrow airport on Monday, the statement said.
The oil has since been delivered to Chelsea and Westminster Hospital where Billy is being treated, but may not be taken home.
The young boy went 19 months without a seizure while he was using the cannabis to treat his condition.

He became the first person in the United Kingdom to receive a prescription after his local GP in Northern Ireland, Brendan O'Hare, began writing scripts.

She said her son was too ill to travel to Canada to get his medication.
Charlotte said that the Home Office would be responsible for for Billy's death.
