I agree with this, it’s already started.
Yesterday I sent my runner to one of the head shops shown on the map posted on the ‘Coconuts’ website, as I couldn’t get away from work.
I was interested in trying some of their medium range stuff (@ 2,000 Baht per 3.5g).
Also, as I have only smoked brick weed for the past 20 years, I wanted to get 3g of their local Sativa (@ 250 Baht per gram), to see if it was any good as a more affordable long-term smoke.
Got a call from the runner when he got to the shop, he was told that they had sold out of everything in their lower price range and the cheapest available is now 750 Baht per gram.
The prices that are currently being offered, by all shops that I have seen offering, are ridiculously high.
