Medical marijuana legislation to be continued...

Update 13 December 2018: Two of the cannabis bills have been approved in Parliament.

These are the Medical Marijuana Industry bill and the Medical Marijuana Amnesty Bill.
The third Bill “Permitted Use of Cannabis for Religious Purposes Bill 2018”, was withdrawn after members of the Rastafarian community told the government that a law could not give them permission to use marijuana, which they consider a sacrament. Jah Mon.

10 December 2018: The draft bill about legalization of medicinal cannabis in St. Vincent and the Grenadines still has not been debated in Parliament. Several experts have been clarifying and explaining legal and economical issues that legalization would involve. The debate is scheduled to start December 10th, we'll keep you updated.
By now it is clear that the governments main aim is (as it should be) that by legalizing medical marijuana the local stakeholders benefit.
This would especially happen if investors with specialized extracting and processing knowledge stepped in to prepare the products suitable for the export market and by doing that get everybody to make more money, less worries.
