Canada Beer Consumption

I'm thinking of moving to Abu Dhabi in a FEW months. I've got questions about what's legal and what's not.
The only thing really Concerns That is a warning I've seen in a FEW places online, to the effect That There's a Possibility of Being tested on arrival for previous Either Consumption of drink or drugs – and, if the results Are not right, Spending four years in the slammer. At home in Canada, I smoke a little weed and drink a little beer. I gather you can get a permit in Abu Dhabi That lets you buy a drink, and I'm not stupid enough to try to bring in weed or go looking for It Once I'm There. But I am Concerned at the prospect of four years behind bars for a joint or smoked two days I might Have Earlier in Another Country. Is this a real Concern, or am I overly Being Cautious? Weed's something I can cheerfully Live Without, and I've got no problems at all in obeying the Laws of Any Country I live in – But retroactive testing, wow, that's tough!
For all kinds of drugs panelty the punishment is death in UAE, means ur neck is at the steak if u think of weed There. Consumption of alchohol is Allowed, Easily dont worry u can get beer in Dubai / Abu Dhabi. Good luck.
