Cannabis a new beginning!
Tom Chapman
Essential Nutrition Ltd, UK
Cannabis is probably the most researched plant in
the world at the moment and it hasn’t even got a
monograph in a pharmacopoeia. The last time it had a
monograph was in the British Pharmaceutical Codex of
1934 and this was for a tincture which is an alcoholic
dilution of an extract made by immersing cannabis leaves
and seeds in alcohol for a while . It was available on
prescription until 1949. While the monograph cannabis
contained both THC and CBD there are hybrids now
which can produce very high THC with low CBD such
as Dutch Skunk which has 18% THC and similar hybrids
with THC below 0.2% and CBD contents of up to 24% . In
USA cannabis is a recreational drug contains both THC
and CBD whilst in U.K. cannabis with more than 0.2%
THC is illegal but cannabis with only CBD is regulated as
a foodstuff under EU rules. There are many novel dose
forms of CBD , I have seen CBD oil in various strengths
and sublingual sprays which deliver between 10 and
one hundred mg per actuation , I tasted gummy bear
children’s sweets impregnated with 12Mg CBD and
tablets and capsules of various strengths and I believe
a skin patch exists. The serious growers of cannabis are
mainly in the USA in Oregon and California .But there are
growers in Slovakia ,Poland Switzerland and Germany , I
am working with other groups growing cannabis in New
York ,Korea , Mozambique, Vietnam , Laos and U.K.There
are two cannabis products registered and these are
Epidolex and Sativex from GW Pharmaceuticals , one
treats MS and the other Epilepsy and both work in the
cannabinoid receptors.There is great scope for future
licensing of cannabis derived medicines as people use
CBD for pain, rheumatism ,anxiety, depression and even
cancer.They also use it just to feel good , so how many
medicines do that ? Tom Chapman is a Pharmacist who
