In June, the south-east Asian nation took the plant off the banned narcotics list so people could grow, sell and use it for medicinal purposes.
Kitty Chopaka still cannot believe she is allowed to sell real cannabis alongside the cannabis flavoured lollies in her colourful shop in the upmarket Sukhumvit area.
Ms Chopaka admits there was some initial confusion for new dispensaries and curious customers, after the government insisted cannabis was for medicinal and therapeutic use only.
Beer started out in an entirely different direction in life as a child actor in one of Thailand's most popular sitcoms, but after being caught with cannabis he says the stigma ended his acting career.
Government-controlled medicinal cannabis had already been legal for four years, but at the last election in 2019 his party's signature policy was that people could grow and use the plant at home as medicine.
"I think [cannabis was] the thing that stuck out most, some people even called my party the cannabis party," Mr Anutin says.
Within a year they had recouped their $80,000 set up costs and had expanded to grow cannabis in 12 greenhouses with the help of 18 full-time staff.
Out on the land though, others are finding growing cannabis harder than they expected.
The Thai government handed out one million free cannabis seedlings the week cannabis was decriminalised, but for rice farmer Pongsak Maneethun, the dream was over in no time.
"We tried to grow it, we planted the seedling, then when they grew we put them into the soil, but later they withered and died," Mr Pongsak says.
He adds that neither the hot Thailand weather nor the soil in his province in the country's east are suitable for growing cannabis.
"People who have money will want to join this experiment … but grassroots people like us, we wouldn't dare to invest, to take such a risk," he says.
The Dean of Chulalongkorn University's Faculty of Medicine, Dr Chanchai Sittipunt, says there is data suggesting cannabis use among young people can have long-term cognitive effects.
"Even if you are a grown-up man, if you use it long term, I still believe that there might [be] some side effects in the future," Dr Chanchai says.
Dr Chanchai says there is no doubt the world is watching how Thailand's experience with cannabis legalisation unfolds and whether it becomes the Amsterdam of Asia.
"I don't want Thailand to be thought of as that destination, we don't want to be the cannabis haven of the world," Dr Chanchai says.
Public health minister Anutin says his policy "doesn't advocate recreational cannabis use" and the existing public health law is strong enough to clamp down on smoking in public
"Thailand's cannabis policy focuses on medical and health purposes and nothing else," he says
And he has this warning for foreign tourists: "News that it's the land of free cannabis, that you can smoke freely everywhere on our soil, that is fake news and we don't welcome those kind of tourists"
