Just found this on an irish site........possibly of no interest to anyone but me........ Possession of cannabis and cannabis resin is considered in a different way to other drugs. Possession of cannabis or cannabis resin for personal use is punishable by a fine on first or second conviction. From a third offence onwards, possession for personal use of cannabis or cannabis resin incurs a fine and/or a term of imprisonment up to 1 year, on summary conviction and imprisonment for up to 3 years and/or a fine on conviction on indictment. Possession in any other case incurs a penalty of imprisonment for up to 1 year and/or a fine on summary conviction and up to 7 years imprisonment on conviction on indictment. In practice they aren't even that strict at all.
Could be worse... Do you live in Eire or N Ireland? Also, do you know how much would be considered "for personal consumption"?
Live in Eire, personal consumption can vary a little anything 1/2 ounce or under and your grand, alot of the time you'd get away with anything under an ounce aswell, but anyhting over an ounce they wouldn't regard as for personal consumption.
