Legalising cannabis can have major benefits for all citizens. If carried out correctly, everyone will benefit from less crime and stronger rule of law. Legalising the drug will especially help protect young people and may even lower their consumption of the drug. It is also a way of raising taxes for the state, instead of fuelling criminal organisations, which currently control the illegal market.
These benefits are increasingly recognised by the public. Crucial to seeing these benefits come about, is the way legalising cannabis is done and how the drug is priced once it is made legal. There must be a combination of getting the price level right and cracking down on illegal activities to reach the right balance between reducing criminality and avoiding increases in cannabis consumption following legalisation.
To fight the black market, the price of legal cannabis has to be relatively low. For example, it could be set around or slightly below the current illegal price. This will attract current users of the drug away from their existing dealers. But if nothing else is done, this will not be enough to eradicate the black market. Dealers will simply lower their prices to attract customers back. They are able to do this because there is currently a high markup in the illegal market.
There is a large range of prices and cannabis products sold illegally but the average price of high-quality cannabis is roughly US$300 per ounce in London, according to the crowd-sourced website priceofweed.com. This is up to three times as high as production costs based on evidence from the US market.
