The real issue is the import restriction of CBDs of foreign producers. Although they can be purchased online, it is illegal to possess the highly regulated and well known CBD oils of America (Boots in the UK sells these brands indicating their quality and safety, since Boots is a highly trusted health products seller). 

 

This is clearly a trade advantage ploy disguised as a health & safety issue: blocking foreign imports to assist domestic producers, who have dodgy safety practices. It will be interesting to see how long this lasts. 

 

As to the issue of THC in cookies and sweeties. A simple stroll down Khao San will disabuse you of any thoughts as to their rarity. They are everywhere. Start with the cannabis "clinics" in the vicinity of the now-closed Burger King on the east end of the road. 

I have seen quite a few websites now describing their bakery products as being THC or even made with butter made with THC extract which seems illegal, although that is the common recipe for edibles and probably most use it. One website said they used full spectrum cannabis without specifying estimated proportions of THC and CBD. That could imply they just decarb the weed, grind it up and throw it in the mix.  If merely heating weed is not considered a form of extraction, then these products might be theoretically legal. 

 

I imagine there will be a shake out in the edibles business before long.  A few incidents of newbie tourists eating brownies clearly labelled as CBD, eating the whole thing and ending up in psychotic comas could trigger it.  At any rate there will no doubt be more clarity at some point as to what constitutes an extract. 

Wow.

 

This topic morphed from a question about CBD oil into a discussion about edibles.

 

How about answering the OP's question?
