Concern at growing number of domestic cannabis factories

The EU drugs agency has expressed concern at the massive rise in the number of domestic cannabis factories across the continent, including Ireland.

Experts are worried at the increased health risk to users, particularly young people, from more potent herbal cannabis and at the sudden surge in violence associated with the trade.

While surveys show that overall consumption levels of cannabis have stabilised across Europe, and fallen here, authorities are concerned that this progress may be reversed by the sharp rise in the supply of domestically produced herbal cannabis.
