Better alcohol than the 'alien' cannabis drug
John Rentoul (DebateNI, January 9) is right to question the decriminalisation of cannabis here, following Colorado's decision to do so. Our failure to control its consumption does not mean it should be legalised.
Our national drug, alcohol, although harmful to some, is well-understood and plays an important role in society: from the toasting of great events, to the celebration of the Eucharist. It is unlikely that Western civilisation could have evolved without it.
Cannabis, on the other hand, is an alien drug not fully understood. Better the drug you know.
