Chatham-Kent's Medical Officer of Health is cautioning children about drinking too many caffeinated energy drinks.
However, he admits restricting their sale to young people would be impossible.
Doctor David Colby says it very difficult to impose legislation that is impossible to enforce.
Colby says energy drinks are tricky to control because different brands have different levels of caffeine.
"Kids are probably drinking too many caffeinated beverages and there's no doubt that caffeine can be toxic in high doses but what is a high dose," says Colby.
There's a push underway from the Sudbury Health Unit to prohibit the sale of caffeinated energy drinks to children and youth.
That health unit says energy drink sales in Canada have jumped by 638% between 2004 and 2015.
Colby says energy drinks have been blamed for some deaths but he cautions people about that.
"Europeans caffeinate themselves to a much higher degree than we do and there hasn't been a lot of mortality that has been attributed to that," Colby says.
Colby says energy drinks are harmful but they're unlikely to kill you.
"They're smaller people and they're not used to this. So, the idea of getting into a toxicity situation is certainly greater but has this been reflected as a general problem of significant cause of lethality in the population, not really," says Colby.
