Oil, real estate, marijuana.  

If you smell cigarette smoke, marijuana smoke, or something else burning, track it to the source.

Lots of marijuana grows in the area.

@Omni Casey...your offer to help Jonny Flores close on his 1st deal to me is amazing and therapeutic on so many levels.

Is it OK to smoke medicinal marijuana outside the unit?

Although oil plays a very large role in the Alberta economy, the main cities of Calgary and Edmonton have been doing a lot of work to try and diversify their economy via attracting tech companies, the booming marijuana sector, as well as health care, post-secondary education etc.

They implemented this when marijuana was legalized and they say growing cycles are 3-months and they want to ensure they are not happening in the properties.

No blinds, get ready for all kinds of original window coverings, including cardboard, Communist guerilla hero flags, sports flags, and my personal favorite to date, a printed banner with a marijuana leaf and "STAY TRIPPY" printed on it.

Do you think it is due to the new legalization and wide acceptance of marijuana? 

Even if marijuana is legal in your state, you should have a policy against smoking indoors and a "right to quiet enjoyment" clause that essentially tells them to be good neighbors.I would give the smokers a written warning that their smoking is bothering the neighbors.
