The Condom Access Project allows youth between the ages of 12 and 19 to order a package of 10 condoms, lube and health brochures online at TeenSource.org, a website run by the nonprofit California Family Health Council. The package will be mailed to them in a nondescript yellow envelope.
Supporters, including state health officials, say the program will help young people who can't afford to buy condoms, or who are too embarrassed to get them at clinics.
But critics say this may not go over well with parents, many of whom see it as approval of teen sex.
The program is being paid for with federal funds.
Teens will be limited to one package of condoms per month.
