University of British Columbia professor and researcher for the B.C. Centre on Substance Use, M-J Milloy says the link between cannabis and brain development is still merely by association. There a great number of scientists worldwide working on this issue, but there’s been no smoking gun, Milloy said.
Zach Walsh, another UBC researcher specializing in cannabis, concurs.The evidence is weaker than the rhetoric; According to Walsh, there appears to be a link between schizophrenia and other psychosis and marijuana use, but this could just be an association rather than causal. He notes that there’s been a dramatic increase in cannabis use in recent years, especially in Canada, but schizophrenia levels have stayed stagnant. www.vancourier.com/news/4-19-pot-panel-wants-to-clear-the-air-regarding-cannabis-and-youth-1.23270407

Our data show that daily cannabis users had no greater risk than non-users (control group) to experience serious adverse events,’’ explains Dr. Aline Boulanger, director of the pain clinic at the Centre hospitalier de l’Université de Montréal. ‘’We found no evidence of harmful effects on cognitive function, or blood tests among cannabis consumers and we observed a significant improvement in their levels of pain, symptom distress, mood and quality of life compared to controls. www.ncbi.nlm.nih.gov/pubmed/26385201

Harvard University study
Evidenced that teen cannabis consumption is not lead to the development of schizophrenia later in life. The study compared families with a history of schizophrenia to those without. The study also examined non-psychotic cannabis consumers and non-consuming participant controls. The results of the current study suggest that having an increased familial morbid risk for schizophrenia may be the underlying basis for schizophrenia in cannabis users and not cannabis use by itself. www.ncbi.nlm.nih.gov/pmc/articles/PMC4319545
September 2002 “The Senate Special Committee on Illegal Drug Use” studied the cannabis issue extensively.
Senator Pierre Claude Nolin, Chair of the Senate Special Committee on Illegal Drugs. Their unanimous recommendation was that cannabis be legalized in a regulatory framework similar to alcohol.
“Scientific evidence overwhelmingly indicates that cannabis is substantially less harmful than alcohol and should be treated not as a criminal issue but as a social and public health issue” www.SenateReport.ca

The idea isn’t being welcomed by Keith Fagin of the cannabis advocacy group Calgary420. He says cannabis users deserve somewhere public where they can gather to smoke, vape or eat the drug.

Cannabis and driving studies

Crash Fatality Rates After Recreational Marijuana Legalization in Washington and Colorado. Evaluate motor vehicle crash fatality rates in the first 2 states and compare them with motor vehicle crash fatality rates in similar states without recreational marijuana legalization.
Automobile crash fatality rates in Washington and Colorado were no different from comparable states without legal recreational cannabis. http://ajph.aphapublications.org/doi/abs/10.2105/AJPH.2017.303848
The U.S. Department of Transportation report suggests that while cannabis could potentially impair driving skills, its findings in other research suggest drivers under the influence of cannabis are actually more cautious. “Subjects in most of the simulator and instrumented-vehicle studies on marijuana are driving typically drive slower, follow other cars at greater distances and take fewer risks than when sober,” the report said. http://www.nhtsa.gov/staticfiles/nti/pdf/812117-Drug_and_Alcohol_Crash_Risk.pdf

Drivers under the influence of cannabis are acutely aware of their impairment. They consciously try to drive more cautiously, by slowing down, focusing their attention and avoiding risks.
Cannabis addiction Business Insider – We took a scientific look at whether weed or alcohol is worse for you, deaths and addiction

There have been zero documented deaths from marijuana use alone.
Marijuana appears to be significantly less addictive than alcohol.” http://www.businessinsider.com/alcohol-marijuana-which-worse-health-2017-11
Philippe Lucas, VP at Tilray, a research scholar with the University of Victoria’s Centre for Addictions Research of BC, said cannabis dependency isn’t as severe as some make it out to be. Normally, people are able to give up cannabis on their own, compared to severe drugs,
Lucas, the lead author in a September 2015 study in the “International Journal of Drug Policy”, a peer-reviewed publication found medical cannabis can be a safe and successful substitution for other addictions to alcohol 25% reduction, 32% for opiates, 12% tobacco, and more. The study has been updated and published August 2017, “Rationale for cannabis-based interventions in the opioid overdose crisis” in the Harm Reduction Journal.
Organized crime Canadian Drug Policy Coalition– Organized crime in the cannabis market:- Evidence and Implications
“2. Unsubstantiated media and police reports portray the cannabis industry as dominated by organized crime.”
“3. Evidence suggests a very low involvement of organized crime in the cannabis industry in Canada; the majority of those in the industry tend to be non-violent and have minimal, if any, involvement with other criminal activities

November 2017 Dr. Elaine Hyshka, “There are also people who claim that cannabis is going to basically damage your brain when you use it, especially if you’re young, and that it’s going to contribute to the intellectual downfall of a generation. And that’s also not true,” she said.

Boyd is a member of Liberal government “Task Force on Marijuana Legalization and Regulation”
The Government of Canada has committed to legalizing, strictly regulating, and restricting access to cannabis. In April 2017, the government introduced Bill C-45, the proposed Cannabis Act. Subject to the approval of Parliament, the Government of Canada intends to bring the proposed Cannabis Act into force no later than July 2018.
