You're full of baloney  **** Stephen Harper just look at Justin he's not brain dead yet!

Harper's claim pot is 'infinitely worse' than tobacco contains 'a lot of baloney'

OTTAWA — "Tobacco is a product that does a lot of damage. Marijuana is infinitely worse and it's something that we do not want to encourage." — Conservative Leader Stephen Harper.

Canadians have one of the highest rates of cannabis use in the world, and a relaxation of marijuana laws is now an election issue.

It's a path Conservative Leader Stephen Harper vehemently opposes, using it to drive a wedge between him and Liberal Leader Justin Trudeau, who wants to legalize marijuana. After Harper clashed with Trudeau over the issue last week, the prime minister was asked Saturday why he was so opposed.
"There's just overwhelming and growing scientific and medical evidence about the bad, long-term effects of marijuana. We've spent a couple of generations trying to reduce the usage of tobacco in Canada with a lot of success," Harper said.

"Tobacco is a product that does a lot of damage. Marijuana is infinitely worse and it's something that we do not want to encourage."

So, is cannabis "infinitely worse" than tobacco?

Spoiler alert: The Canadian Press Baloney Meter is a dispassionate examination of political statements culminating in a ranking of accuracy on a scale of “no baloney” to “full of baloney” (complete methodology below).

Marijuana does carry health risks and there is growing medical evidence about long-term health effects, but there is "a lot of baloney" when it comes to marijuana being "infinitely worse" than tobacco.

Let's sort through the haze.

THE FACTS

While there is about 20 years' worth of research on the health effects of marijuana, the science is still evolving about how the level of usage and the potency of strains affect health.

A report from the Centre for Mental Health and Addiction in Toronto, citing multiple research studies, said that daily or near-daily use of marijuana can affect cognitive and psychomotor functioning by slowing down how quickly one thinks and acts. The report also ties regular, long-term cannabis smoking to respiratory problems with links to bronchitis and cancer.

Frequent marijuana use could also exacerbate pre-existing mental health issues, although that link is not well understood.

There are also concerns about addiction. About one in every 10 cannabis users risks becoming dependent. The rate for tobacco users is much higher at 68 per cent.

Each year, about 37,000 Canadians die as a result of smoking tobacco. Tobacco use costs the health care system an estimated $4.4 billion.

The Canadian Cancer Society says that tobacco smoke contains more than 4,000 chemicals, with more than 70 per cent of those chemicals being carcinogens. Among the four leading causes of death in Canada — cancer, heart disease, stroke and lung disease — smoking tobacco is a main risk factor.

The society says that smoking tobacco is estimated to be responsible for almost one-third of all cancer deaths, and 85 per cent of all lung cancer cases.

THE EXPERTS

Research has shown that about four per cent of marijuana users report some sort of health, legal or financial trouble, said David Hammond, the CIHR Applied Chair in Public Health at the University of Waterloo. The amount for tobacco is higher: anywhere between 30 and 50 per cent, Hammond said, suggesting that tobacco use carries more health concerns than marijuana use.

Heavy, long-term use of marijuana by teens has been linked to an increased risk of schizophrenia-related mental health disorders in early adulthood, said Steven Laviolette from Western University’s Schulich School of Medicine & Dentistry, who researches the effects on the brain of nicotine and THC, the psychoactive chemical in marijuana. However, Laviolette said, those teenagers are using marijuana with a heavy amount of THC. (One potent strain has 18 per cent THC; medical marijuana in Canada tops out at about five per cent.)

Research has also shown these teens may have a genetic predisposition to developing mental health disorders, he said, blurring links between smoking marijuana and mental health issues. As well, a chemical in marijuana, known as CBD, has been shown to be an anti-psychotic that counteracts THC, Laviolette said, creating a debate with more subtleties than political sound bites allow.

The Canadian Cancer Society says research linking marijuana smoking to increased cancer risks "is not as strong or comprehensive as the evidence that links tobacco use and cancer." Part of the problem is that marijuana smokers also use tobacco and sometimes mix the two substances.

With mental health issues, the science isn't conclusive because marijuana use may exacerbate underlying issues.

"We certainly know enough to know that there are important risks," Hammond said.

"We don't know exactly the level of some of those risks and the direction of causality — is it just people who are already struggling that start using marijuana? — but we certainly know enough to know that youth should be discouraged from using this. Pregnant mothers should be absolutely discouraged from using this."

THE VERDICT

Marijuana does carry some health concerns — of that there is little debate. Saying it is "infinitely worse" than tobacco is "a lot of baloney" on the CP scale. The data on marijuana use and the links to health appear to be focused on heavy use of high-potency strains by teenagers and pregnant women, with fewer side effects found in casual, adult marijuana users.

"In terms of the statement that marijuana is infinitely more harmful than tobacco, there's simply no evidence at all to suggest that's true either in terms of health care costs, or in terms of relative health dangers," Laviolette said. "The cancers and other source of pulmonary diseases associated with smoking — to use the word infinitely — are infinitely more serious than what we would ever encounter with smoking marijuana and that's well-established."

Hammond said both substances carry harms and risks to users, "but the harms and risks from smoking are significantly greater than marijuana use."

METHODOLOGY

The Baloney Meter is a project of The Canadian Press that examines the level of accuracy in statements made by politicians. Each claim is researched and assigned a rating based on the following scale:

No baloney — the statement is completely accurate
A little baloney — the statement is mostly accurate but more information is required
Some baloney — the statement is partly accurate but important details are missing

A lot of baloney — the statement is mostly inaccurate but contains elements of truth

Full of baloney — the statement is completely inaccurate
