The cultivation of cannabis in Ireland is on the increase and home grown versions of the drug appear to have a higher potency than imported versions, a new study has revealed.
The aim of the research, which was carried out on behalf of the National Advisory Committee on Drugs (NACD), was to establish the THC content of cannabis available in Ireland.
THC (tetrahydrocannabinol) is the main psychoactive part of cannabis - in other words, the part that affects a person's mind or behaviour the most. According to NACD chairperson, Dr Des Corrigan, ‘there is growing concern about rising THC levels particularly in herbal cannabis of the ‘skunk' or ‘weed' variety'.
