At a conference at GW Pharmaceutical's headquarters in Porton Down, Wiltshire, Professor H.P. Hartung, Chair of Neurology at Heinrich-Heine University, Dusseldorf, Germany announced that Sativex, the super strong, concentrated cannabis medicine has "...limited relevant adverse effects and - particularly reassuring - the drug does not appear to lead to withdrawal effects if patients suddenly stop using it." Full details here.
Sativex is made from high-THC skunk cannabis blended with a high-CBD variety and concentrated into a super strength solution that can be used to treat MS , chronic pain and, scientists believe , many more previously unrelieved conditions.
Super strong, concentrated cannabis is safe. It's not addictive. It doesn't cause psychosis. There are virtually no side effects.
