Re "Cannabis 'obvious' threat to health, agency says" (Feb 20).

The World Health Organization is now backtracking after a leak
of its own report showed that marijuana is not the demon weed
everyone has been fooled into thinking it is.

Now WHO narcotic drugs head Tokuo Yoshida says that cannabis
"must not be used because it changes your judgement and thinking."

Alcohol changes your judgement and thinking, as does post-secondary
education, spirituality and, as Parliament has been making clear to us
with their silence on the marijuana issue, election to public office.
Should we ban those things as well?
