Thailand is trying to rein in its free-wheeling marijuana market.

The government has approved new measures, which will soon restrict consumption of the drug to those with a doctor's prescription - in the hope that this will help regulate an industry some describe as out of control.

The public health minister has also said that consumption of marijuana will be criminalised again, although it's unclear when that could happen.

Ever since the drug was decriminalised in 2022, there has been a frenzy of investment.

There are now around 11,000 registered cannabis dispensaries in Thailand. In parts of the capital Bangkok it is impossible to escape the lurid green glare of their neon signs and the constant smell of people smoking their products.
