Jamaica's Cabinet has approved new laws to decriminalise possession of small amounts of pot and pave the way for a legal medical marijuana industry on the Caribbean island.

Justice minister Mark Golding said he expects to introduce the much-anticipated legislation in the Senate by the end of this week.

Debate could start before the end of the month in the pot-steeped country where the drug, known popularly as "ganja," has long been culturally entrenched but illegal.

Mr Golding said the bill would establish a "cannabis licensing authority" to deal with the various regulations needed to cultivate, sell and distribute marijuana for medical, scientific and therapeutic purposes.

"We need to position ourselves to take advantage of the significant economic opportunities offered by this emerging industry," the minister said.

It would make possession of 2 oz or less a ticketable offence that would not result in a criminal record. Cultivation of five or fewer plants on any premises would be permitted.

Rastafarians who use marijuana as a sacrament could also legally use cannabis for religious purposes for the first time in Jamaica, where the spiritual movement was founded in the 1930s.

For decades, debate has raged in Jamaica over relaxing laws prohibiting ganja. But now, with a number of countries and US states relaxing their marijuana laws the Jamaican government is advancing reform plans.

Mr Golding stressed that the government will not soften its stance on transnational drug trafficking and it intends to use a portion of revenues from its new licensing authority to support a public education campaign to discourage pot smoking by youngsters and mitigate public health consequences.
