Antony Alexander (letter, 6 March) fears the demotivating and dispiriting
effect of cannabis on regular users.

He couldn't be more wrong.

A year ago I had the pleasure of living for a time with a Moroccan farmer
and his family. He and his co-workers smoked dope from dawn till dusk and
had done so for years. They showed no lack of motivation and were great
fun to get to know.
