Education Law, Article 132, section 6551(3), states that chiropractors licensed in this State may not "prescribe, administer, dispense or use in his practice drugs or medicines." Such durable medical equipment as cervical collars, cervical pillows, traction kits, support belts, whirlpool equipment, orthotic and other non-electrical devices are not "drugs or medicines." Consequently, such items may be purchased without prescription, and, thus, may be ordered or recommended by chiropractors for their patients within the definition of chiropractic practice in Article 132.
