Medical journal says pot law will harm youth

Share

“The bill as it is written should not pass,” says Dr. Diane Kelsall, editor of the Canadian Medical Association Journal. She has authored an editorial expressing her concern that the proposed new law would “increase harm to young people.”

The federal government’s Bill C-45 would legalize the recreational use of marijuana and would make the minimum age for the purchase of pot 18. “We know that brains continue to develop till about the age of 25,” says Kelsall.

‘Why not pick an older age?’

“So, take a developing brain, put marijuana in there and of course you’re more likely to get some of these adverse effects. So, why did they pick 18? Why did they not pick an older age?”

The adverse effects she is talking about are not proven to be caused by marijuana but are associated in those who use it regularly. They include dependency, a stronger likelihood to use other drugs or tobacco, mental illness, depression, psychosis, anxiety.

‘Lifetime achievement will be less’

“We know that it (regular marijuana use) is associated with teenagers not doing well at school, dropping out of school, and in fact, their entire lifetime achievement will be less than those who don’t use marijuana,” says Kelsall.

“And we know that it’s also been associated with impaired neurologic development and a decline in reasoning and thinking.”

Potency not controled

She is also concerned that the proposed law places no limits on marijuana potency and allows people to cultivate four plants each of a maximum of one metre tall. People, she says can seek the most potent plants and grow them horizontally.

The bill would leave certain rules, such as age limits, up to each individual province and territory. Kelsall says this would lead to situations such as exist now with alcohol where youth travel over a bridge from Ottawa, Ontario where the legal drinking age is 18 to Gatineau in the province of Quebec where the legal age is 19.

Bill fails to protect public health, says doctor

Says Kelsall, the federal government said it would pass a marijuana bill that would protect public health, but this version fails to do that.

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.

Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.

One comment on “Medical journal says pot law will harm youth
  1. Avatar James Tripp says:

    It never ceases to amaze me that our medical community can remain so oblivious to the vast array of beneficial medical properties the 100+ phytocannabinoids contained in the cannabis plant can provide to the human Endocannabinoid system thus returning the patient to a much more positive state of physical and mental health! .

    Our prime minister promised to use best practices and best science in the formulation of his party’s cannabis policy but that is not what is happening.

    Our government is being informed by organizations that are pervaded by negative bias against all forms of cannabis use and as a result our legislation we will be full of flaws based on Gross misconceptions regarding how cannabis affects individual human physiology.
