Welcome back to The Week in Weed, your Friday look at what’s happening in the world of legalized marijuana.

We’re about six weeks away from the legalization of marijuana in Canada, but Canadian marijuana stocks are already on the New York Stock Exchange.

Canopy Growth late Wednesday said it expects to begin trading on the NYSE tomorrow, making it one of two Canadian pure-play marijuana stocks to list on a major U.S. exchange.

The only pureplay marijuana stock with any shot at being added to the S&P 500 anytime soon is Canadian-based Canopy Growth Corp.

In Florida, a circuit court judge has ruled a medical marijuana smoking ban unconstitutional.

A Florida judge has ruled the state’s ban on smoking medical cannabis unconstitutional, calling the Legislature-approved ban “invalid and unenforceable.”

In a move that could potentially provide an even bigger boost to growers and retailers in one of the country’s fastest-growing markets, a Florida judge ruled the state’s ban on smokable medical marijuana is unconstitutional.

Cannabis is apparently not immune from the laws of supply and demand, as proven by the situation in Oregon.

When Oregon lawmakers created the state’s legal marijuana program, they had one goal in mind above all else: to convince illicit pot growers to leave the black market.

State regulators say Oregon produced enough recreational cannabis last year to supply every adult resident with more than 5 ounces (140 grams) of legal marijuana.

And finally, birthday greetings to Tommy Chong, who, believe it or not, recently turned 80.

Yeah man, Tommy Chong says he always knew he’d live to see the day marijuana legalization would be sweeping the country.
