Edible Cannabis Use May Carry Unexpected Risks
Experts warn there could be unexpected health risks from eating foods containing the drug cannabis. Those risks include accidental overdose, children eating them accidentally and unexpected effects in older adults.
The commentary by doctors Lawrence Loh and Jasleen K. Grewaland appeared in the Canadian Medical Association Journal.
Loh is with the Dalla Lana School of Public Health at the University of Toronto. He said, "What we really want the public to know is that legal doesn't mean safe. People need to know that how they react will depend on the manner cannabis is consumed, the amount that is consumed and the person's own metabolism..."
Loh said it can take hours for the cannabis high to take effect if the drug is eaten instead of smoked. So, he said, people might eat more of the cannabis as they wait for the high to happen.
While a cannabis overdose will not kill you, it can be unpleasant, Loh said. He added, "We suggest people start with a low dose and go slow."
Loh and Grewaland also advise older adults be extra careful with edible cannabis. They could be at greater risk for falls and injury, especially those who are not used to the drug's effects.
Loh also warns that adults should be mindful that edible cannabis products might interest children. Loh said the drugs should be stored carefully "to make sure kids can't get into it."
Loh and Grewaland also suggest that doctors add questions about cannabis to those they usually ask a patient, so they can offer education and advice.
A warning such as this one "is really important," said Dr. Michael Lynch. He is medical director of the Pittsburgh Poison Center and with the University of Pittsburgh School of Medicine in Pennsylvania.
Lynch said the risk of dying from an overdose is low. But he added that the risks of medical problems or injury is very real. "The greatest risk is to the young and the old," he said.
Lynch said those who overdose would be at risk for falls, vomiting and weakness.
An increase in heart rate and blood pressure could also be more of a problem for older people, Lynch said.
He added, "People need to be educated about the risk so these outcomes can be avoided."

专家警告称，食用含有大麻的食物可能会带来意想不到的健康风险 。这些风险包括意外过量摄入、儿童误食以及对老年人的意外影响 。
医生劳伦斯·罗(Lawrence Loh)和贾斯林·格雷瓦兰(Jasleen K. Grewaland)的评论发表在《加拿大医学协会杂志》上 。
罗就职于多伦多大学达拉拉纳公共卫生学院 。他说：“我们真正想让公众知道的是，合法并不意味着安全 。人们需要知道，他们的反应将取决于吸食大麻的方式、摄入量以及自身的代谢能力……”
罗表示，如果是食用大麻而不是吸食，大麻兴奋的效果可能需要数小时 。所以，他指出，人们在等待兴奋到来的时候可能会食用更多的大麻 。
罗还指出，虽然过量吸食大麻不会致命，但也会让人不适 。他补充说，“我们建议从低剂量开始，慢慢来 。”
罗和格雷瓦兰还建议，老年人食用大麻时要格外谨慎 。他们摔倒和受伤的风险更大，尤其是那些不适应大麻效力的人 。
罗还警告称，成年人应该注意，可食用的大麻产品可能会引起儿童的兴趣 。罗指出，大麻应该谨慎放置，“以确保孩子们不会接触到 。”
迈克尔·林奇(Michael Lynch)医生指出，这样的警告“真的很重要” 。他是匹兹堡毒药中心的医学主任，并任职于宾夕法尼亚州匹兹堡大学医学院 。
林奇表示，死于服药过量的风险很低 。但他补充说，医疗问题或受伤的风险是非常现实的 。他说，“最大的风险在于年轻人和老年人 。”
