I concur with my fellow mental health worker Tony Stubb's observations (Letters, Sept 3) about the damage to mental health that can result from cannabis use.

As a worker within the local Community Mental Health Team, I detect similar harmful influences from both religion and families.

However I don't believe the mechanisms of law and its enforcement are either practical or desirable in curtailing these ingrained habits.

Education is the only course which will provide positive and lasting results - part of which will be, of course, open debate within the pages of The Argus.
