None the less order 1 mg arimidex with visa, the widely reported eff- cacy of herbal cannabis relative to standard prescribed drugs for a large number of individuals with chronic illnesses order 1 mg arimidex with amex, who do not ft the bill as stereotyped drug users generic arimidex 1 mg fast delivery, has forced the issue. Thirteen states now allow the use of medical cannabis—they are Alaska, California, Colorado, Hawaii, Maine, Maryland, Montana, Nevada, New Mexico, Oregon, Rhode Island, Vermont, and Washington. As a result, there have been a series of unpleasant enforcement incidents, with federal police closing down medical production and dispensaries that were offcially sanctioned by state governments. These patients have been provided with medical cannabis for between 11 and 27 years. Material is shipped to the Research Triangle Institute in North Carolina where it is chopped and rolled on modifed tobacco cigarette machines, then stored partially dehydrated and frozen. Legal cannabis production in Canada A similar scenario has played out in Canada where, in 2001, medical use of cannabis was legalised in restricted circumstances through the 180 Canadian Department of Health’s Medical Marihuana Access Division. According to their Marihuana Medical Access Regulations, individuals can get licences to produce their own supply of cannabis, or a licence can be given to another designated individual to grow on their behalf. In 2000 Canada’s department of health, Health Canada, contracted Prairie Plant Systems, on behalf of the federal government, to grow cannabis in an underground mine at Flin Flon Manitoba for research purposes, and in 2003 to distribute to the expanding number of medical users in the 180 Health Canada website: 210 www. Along with the estimated 600 users of the Prairie Plant Systems 183 cannabis there are over 11,000 users of ‘compassion clubs’ in Canada. These clubs act as medical cannabis dispensaries, supplying cannabis for therapeutic use upon a valid recommendation or confrmation of 184 diagnosis from a licensed health care practitioner. Whilst the Senate 185 Special Committee on Illegal Drugs and other government bodies have recommended that these organisations be licensed and legally recogn- ised, currently they are operating without legal sanction. They set clearly defned standards, including demands that a variety of strains be offered 181 Health Canada’s Medical Marihuana Access Division website: www. Report of the Senate Special Committee on Illegal Drugs’, Summary Report, September 2002, page 20. Cultivators must also protect the cannabis from yeasts, moulds, mildews and fungi. Whilst small scale cultivation for personal use is tolerated (as elsewhere in Europe), larger scale production or importation for supplying the coffee shops is not, and has been the subject of an increasing enforcement effort over the last few years. In previous decades Dutch criminal enterprises were more closely involved in European and international cannabis trafficking but an enforce- ment push in the late 1990s dismantled much of this activity and coincided with the expansion of domestic illicit production, both in the Netherlands and elsewhere. Domestic production of herbal cannabis now constitutes 75–80% of coffee shop sales, and whilst it is unregulated in terms of strength and contamination it is considered to be of generally good quality. There is no reliable data available, however, a substantial proportion of domestic Dutch production is still thought to be for export to neighbouring countries. The exported cannabis is rumoured to be of lower quality, and thus not acceptable in the coffee shops—it is supplied as vacuum sealed product more easily bulked up with non-cannabis materials. Most hash/resin form cannabis in the coffee shops is still imported from Morocco, through established illicit routes. It is associated with one of the main Hindu gods—Shiva—and is also used openly during tradi- tional annual festivals, most commonly the spring festival of Holi. Government bhang shops were, and in some cases still are, prevalent throughout large parts of India. Under the 1961 Single Convention they, like many other countries who had what was described as ‘traditional use’ of scheduled drugs, were obliged to end the use of such substances within 25 years. In a similar fashion to the traditional use of the coca leaf in the Andes this has, perhaps unsurprisingly, not happened (the 25 year window perhaps being a signal that it was never likely to either). There are still ‘official’ government bhang shops in some cities such as Varanasi and Puri (and others across Rajasthan), and it is still widely used during religious festivals, as well as on a more regular basis by a small number of holy men or Sadhus. Production of the bhang, which is relatively low potency and most commonly eaten or in a beverage, is essentially unregulated, operating much like production of herbs and spices. These cannot be legally restricted or controlled as they have a wide range of other legitimate uses. Given this reality, small scale domestic produc- tion has become increasingly popular and widespread, supported by a burgeoning industry in growing guides and literature, technology and paraphernalia. This development has been facilitated by the diffculty in legislating against the distribution of cannabis seeds, which do not 186 themselves contain the active drugs.
