Someone wrote an article online, mentioned the first state had acupuncture legislation was California, actually this is a wrong information. The first state should be Nevada. Maryland and Oregon were in the same year (1973) immediate after Nevada. Washington DC was in 1989. Virginia in 1993.
Below is a list from American Association of Acupuncture and Oriental medicine(AAAOM).
State Legislative Initiatives: The first practice act legislation was enacted in 1973 in Nevada Maryland and Oregon. Today, 44 States (PDF), plus the District of Columbia have enacted practice acts.
1973-Maryland, Nevada & Oregon
1974-Hawaii, Montana, South Carolina
1975-Louisiana, New York(I think), and California
1981-Florida & New Mexico
1983-New Jersey & Utah
1989-Colorado, District of Columbia, Wisconsin
1991-New York(I think this should be the year for re-publishing the sate law)
1993-Iowa, North Carolina, Texas, Virginia
1997-Arkansas, Illinois, New Hampshire
2000-Georgia, Ohio, Tennessee
