" if you can figure out how to get the taste of pot out of a cookie, I could use that recipe, please!"

I personally take my cooking herbs, put them in a coffee grinder, then sautee it in butter and a small amount of brown sugar until it becomes slightly crispy...grind the herbs again (I use a mortar and pestal) The you have a good base for sweet baking and cooking that has no fiberous texture and has very little if no taste in the finished baked good, saying you didn't use 5 grams per cookie

As for proper ventalation, You need to be able to completely exchange the air in your cabinet in 5 minutes or less. So calculate the cubic feet if your cabinet (L x W x H) and divide it by 5 and your number is the minumum cfm needed to vent your cabinet. As for hiding smells, ionizers work well as do carbon or charcoal filters, but by far the best way is to have a closed circulation system so no air escapes to the outside.
