The International Hemp Association is a non-profit organization established in 1992 to promote the beneficial uses of hemp products worldwide.  The organization encourages and facilitates the accumulation and exchange of information on Cannabis, sponsors projects in several countries and publishes a journal for its members.  The IHA is supported by memberships and by donations from foundations, corporations and individuals.
Although many IHA members may feel that in light of the great economic potential of Cannabis, the current legal restrictions hampering Cannabis research and hemp cultivation should be reconsidered, the IHA does not endorse a political stance on Cannabis legislation, nor will it serve as a forum for the Cannabis legalization debate.

The IHA has three types of membership; Student (US $25/NLG 40 per year), Individual (US $50/NLG 80 per year) and Sustaining/Business (US $100/NLG 60 or more per year).  Membership participation will be balloted.  Members may order additional or previous issues for US $10 (postpaid), non-members pay US $15 (post-paid).  Members joining after June may join for the next year and purchase the issues of the current year.  Payments may be made by International Postal Money Order, American Express/Thomas Cook Money Order, or via AmEx credit card.

Authors who contribute an accepted article to the journal will receive a year's membership including subscription to the journal.  Sustaining members can direct their contribution toward any specific project they prefer.  A financial audit of income and expenditures is available to sustaining members.

Submission of manuscripts
The IHA Journal publishes original research, literature reviews and news items on hemp.  Preferably, contributions should not exceed 10 double-spaced typed pages (ca. 4000 words).  Longer contributions may be accepted if they can be serialized in two consecutive issues.  Manuscripts can be submitted in triplicate to: IHA Journal, Editorial Office, Postbus 75007, 1070 AA Amsterdam, The Netherlands.  Once a paper is accepted, the preferred medium of submission is on disk (Macintosh or MS-DOS format), preferably MS Word 5.0 or later, with accompanying manuscript.  A guide for authors can be found on page 65 of this issue or can be obtained from the IHA.
