Cannabis users are exposing themselves to "higher risks of psychosis" by smoking super-strong homegrown herbal cannabis.
Research shows that herbal cannabis grown in factories here imposes a double whammy on users through a combination of high potency and the lack of protective chemicals typically found in cannabis resin.
Resin dominated the Irish cannabis market for decades, but there has been a shift to the herbal variety over the past five years. This switch has been particularly dramatic in the past three years, as the number of cannabis factories has soared.
A report conducted by the Forensic Science Laboratory (FSL), on behalf of the National Advisory Committee on Drugs (NACD), found that herbal cannabis seized here tended to be around three times the strength of resin.
