Nevertheless, it should be pointed out

'intermediate drug' chemotype, selected for
their particularly high Δ-9-THC content, are
easily recognized morphologically. This is
because they present hypertrophied resin-
secreting hairs on their flowering or fruiting
heads.
has allowed a selection programme to be imple-
mented based on agronomic and chemical
criteria.
The different stages in the selection pro-
cess conducted in France over the past 15 years
is based on chemical criteria and has allowed
Δ
-9-THC-free varieties (Santhica 23 and
Santhica 27) to be offered to the user indus-
tries. This work is ongoing and it is reasonable
to think that it will be possible to produce, in
the not too distant future, new varieties that
contain no cannabinoids.
Despite the positive results obtained from
chemotype selection, the significant similarities
that exist between the different chemical types
mean that we must remain vigilant. Any crop
of hemp can, after all, conceal another…

In France, agroindustry cultivates hemp for
fibre while carefully abiding by current
French and European laws. A thorough
