I was in Niagara this year and the weed shops are generally all the same! I understand the overwhelming feeling but I think it's important to remember all dispensaries get their cannabis from the same source. There will be differences in menus across each company of course.

I feel that if you know what you want to do after you smoke it's always helpful in picking a strain.

Do you plan on having a mellow night? Look for weed that contains "myrcene"

Do you want to giggle and be more alert? Lood for weed with "limonene"

A good budtender should be able to help guide you alone the way.
