I'll give my two cents on this one.
On 1 July recreational use of marijuana will be legal in Canada.
To be honest, I happen to agree that it should be. I'm sitting here drinking beers, so why would I decry and condemn another person's choice of drug. That would be hypocritical.
Do I believe weed is harmless. No, not for one second. I don't care what you've found after spending an afternoon of intensive study at Google University's School of Medicine. It's a drug, and it will have an effect. I laugh at the people who proclaim that marijuana will cure all ailments. So will 'Dr. McCullcaides Medicinal Elixir. Made with ancient herbs from the far East" (Red Dead Redemption, patent medicines).
I digress.
The Trudeau government's decision to legalize marijuana has been a subject of national debate. Not as to whether it should be legal, but how it should be controlled. Unless you want me to launch into a discussion of the division of powers as defined under s.91 and s.92 of the Constitution Act 1867 (which I can do), accept what I'm about to say.
Criminal Law is the preserve of the Federal Government. All they have to do is, by act of Parliament, declare that marijuana is no longer subject to the Controlled Drugs and Substances Act (which is part of the Criminal Code of Canada).
However, regulations as to the sale and control of alcohol and tobacco, of which marijuana will fall, is subject to provincial jurisdiction. I know that some provinces have decided to sell marijuana via agency stores. Namely Quebec (SAQ), Alberta (AGLC), and Ontario (LCBO), others have chosen to sell via privatized dispensaries, others have gone for a mix.
As Lys correctly pointed out, in regards to business. There are numerous employers struggling to determine how to deal with the legalization of marijuana. There are millions of Canadians who work in high risk occupations, that you wouldn't necessarily want stoned out of their gourd who while performing their duties. Under s.8 of the Constitution Act 1982, we are protected from unreasonable search or seizure. The courts have upheld that right and have determined that employers cannot perform drug testing, unless they have reasonable cause to suspect that the majority of their employees are under the influence. Randomized is fine, as long as it is anonymous.
I've noticed that some of you have said, "legalize it and tax the hell out of it."
That defeats the purpose. The idea is to take the sale of marijuana out of the hands of criminals. If it's taxed to high, why would the end user choose to patronize a pot store over "the guy", he/she has always gone to?
Case in point, cigarettes are highly taxed in Canada. A pack of 25 Pall Mall Regs costs $9.80 in Quebec. It can get as high as $16.00 in some provinces for Players, DuMaurier, or RJR MacDonald. There is a thriving black market for smokes.
After the last round of Federal/Provincial debates the tax rate for marijuana was set at $1.00 per gram ($0.75 to the province, $0.25 to the Federal). The various level of governments have stated that the sale of marijuana will not be a revenue stream. Revenue will be lost because of the increased costs of Addiction Awareness, Education, Health Care, Police Training, and etc.
