Faced with evidence of adverse and potentially fatal health effects, Quebec's Health Ministry is contemplating a ban on the sale of caffeinated energy drinks to people under the age of 16.

The province is looking closely at that option amid recommendations from medical groups and a report by Radio-Canada's investigative program Enquête that revealed the undesirable effects of the beverages..

"It's a product that should not be drunk by kids or teens," said Dr. Alexandra Bwenge, a spokesperson for Quebec's association of sports physicians.

"Unfortunately, they're the target market. They're the ones who drink the most. They are the ones who are most sensitive to the harmful effects. And they often drink it in a context of sports activity. "

An unknown condition, a deadly combination

At least seven Canadians have died after consuming an energy drink, according to information compiled by Radio-Canada.

One of them was Zachary Mitchell, 21. He was athletic, active and in excellent physical health.

But in the summer of 2016, he drowned in a lake in the Outaouais region after diving into the water the same way he had countless times before.

"He didn't jump with the same finesse as usual," his mother Heather recounted. He was holding his left side, she said, and he resurfaced and joked around with his friend. But then he slipped back underwater.

Mitchell had brought some cans of Red Bull to the lake, and Quebec Coroner Pascale Boulay said the autopsy showed caffeine in Mitchell's blood "that was compatible with at least, I would say, a minimum of two" cans.

Unbeknownst to anyone at the time, Mitchell had a genetic condition that predisposed him to arrhythmia.

When Boulay got the results of Mitchell's toxicology and molecular analyses, she concluded there was a more than probable link between the cardiac arrhythmia that caused Mitchell to lose consciousness, his physical activity and the consumption of an energy drink.

"All the evidence supports the fact that the energy drinks ... still contributed," Boulay said. "They aren't the cause of death, but they contributed to an arrhythmia. And the fact that Zachary was in the water, well, he went under and drowned."

Ill effects well-documented

Deaths related to energy drinks may be extreme cases. But the adverse effects associated with these products are numerous and well-documented among young people aged 12 to 24.

The most recent Canadian study, by University of Waterloo researcher David Hammond in 2015, surveyed 2,048 people in that age group.

"Nearly half of those who had consumed energy drinks said they had experienced an adverse reaction, such as palpitations, vomiting or convulsions," Hammond said.

But in 2013, energy drinks were categorized as simple foods rather than natural health products. Under that categorization, it's up to the industry itself to report adverse effects to consumers, instead of Health Canada.

If a Red Bull consumer has a health problem, they need to report it to the company, which in turn is responsible for reporting the incident to Health Canada.
