Medical cannabis

The medicinal use of cannabis is not new, as until the 1930s cannabis was a regular component in the chemist's arsenal against pain. At about that time cannabis use was essentially banned in the USA, and eventually throughout the world. Things have now changed, and there has been a general relaxation of the law, particularly in the USA and Canada. Australia and New Zealand are likely to follow the general worldwide trend, but how best to grow the crop for medical purposes has yet to be determined. In this presentation I will provide an introduction to the various types of cannabis, examine some of their different medical properties, suggest how they might be best grown for medical purposes, and consider possible methods by which the cannabinoids are ingested.
