Truly open 24 hours every day. At the time of writing this, Plukpa did not carry distillates, infusions, or edibles. However, their selection of cultivated flower was quite varied and ranged in prices from 300-500 Baht/g. You can use bongs provided by the shop in their smoking lounge or purchase pipes from the shelf. They have free wifi and outlets accessible to patrons for charging phones. They carried drinks, including local craft brews. Perfect place to wait for your flight, as it is located across the street from Don Mueang International Airport. However, I would recommend leaving whatever you do not consume at the dispensary as laws vary from country to country, and while it is legal in Thialand, it may not be in your destination country.
Side note to the proprietor: send me a Bitcoin (Lightning prefered) address so I can donate some Sats for new guitar strings 😉 (on site guitar is available to the public)
